+``pplib``
+=========
+
+``pplib`` is a library for raw PDF access. It parses PDF documents and provides an interface to access document structures in C.
+
+C-API
+=====
+
+Types
+-----
+
+``pplib`` defines several C-types to represent PDF types:
+
+- ``ppint`` - signed integer (``int64_t``)
+- ``ppnum`` - real number (double)
+- ``ppname`` - PDF name
+- ``ppstring`` - PDF string
+- ``pparray`` - PDF array
+- ``ppdict`` - PDF dict
+- ``ppstream`` - PDF stream
+- ``ppref`` - PDF indirect reference
+- ``ppobj`` - a container of all above
+
+Among ``ppint`` and ``ppnum``, we also use ``ppuint`` - unsigned integer (machine word, alias to ``size_t``).
+
+Other API types:
+
+- ``ppdoc`` - PDF document
+- ``ppxref`` - cross-references table
+- ``ppcontext`` - ... later
+- ``pprect`` - rectangle
+- ``ppmatrix`` - matrix
+
+Integer, number, name and string are treated as simple types.
+Names and strings are actually C-structures, but exposed to API as typedefs to ``const char *``.
+Other types (array, dict, stream, reference, object container, xref, PDF) are C-structures,
+and you operate it their pointers. So when you declare a simple type variable you say::
+
+ ppuint u;
+ ppnum n;
+ ppname name;
+ ppstring string;
+ ...
+
+And when you declare a compound type you operate on pointers::
+
+ ppobj *obj;
+ pparray *array;
+ ppdict *dict;
+ ppstream *stream;
+ ppref *ref;
+ ppdoc *pdf;
+
+Some of those C-types are defined in library header ``ppapi.h`` (complete types). Some others are incomplete
+(eg. you can't say ``sizeof(ppdoc)`` or ``sizeof(ppxref)``). This is to avoid unnecesary dependencies in
+the header. [At some points it's not clear to me what to hide and what to expose, will see.] The library itself
+uses ``pplib.h`` but for auxilary applications including a standalone ``ppapi.h`` header should be enough.
+
+``pplib`` was designed having **read-only** PDF access in mind. Even if some structure is completelly exposed,
+so that you can directly access its members, you should treat them as read-only. I don't make them ``const`` because
+then all variable declarations would need to be ``const``, which is annoying, and I'd need some trickery in the library
+internals to unconst. Besides, nothing is really const for C type casts.
+
+Object
+------
+
+A common container for all elementary PDF object types is ``ppobj`` structure. ``ppobj`` has a type identifier
+(integer) and union of values::
+
+ struct ppobj {
+ ppobjtp type;
+ union {
+ ppint integer;
+ ppnum number;
+ ppname name;
+ ppstring string;
+ pparray *array;
+ ppdict *dict;
+ ppstream *stream;
+ ppref *ref;
+ void *any;
+ };
+ };
+
+Object type is one of constants (enum)::
+
+ PPNONE
+ PPNULL
+ PPBOOL
+ PPINT
+ PPNUM
+ PPNAME
+ PPSTRING
+ PPARRAY
+ PPDICT
+ PPSTREAM
+ PPREF
+
+The type determines the structure member you're allowed to access::
+
+ ppobj *obj;
+ ...
+ switch (obj->type)
+ {
+ case PPNONE: // shouldn't actually happen, indicates some failure
+ break;
+ case PPNULL: // valid PDF null object, no value
+ break;
+ case PPBOOL: // do something with obj->integer (ppint), value 0 or 1
+ break;
+ case PPINT: // do something with obj->integer (ppint)
+ break;
+ case PPNUM: // do something with obj->number (ppnum)
+ break;
+ case PPNAME: // do something with obj->name (ppname)
+ break;
+ case PPSTRING: // do something with obj->string (ppstring)
+ break;
+ case PPARRAY: // do something with obj->array (pparray *)
+ break;
+ case PPDICT: // do something with obj->dict (ppdict *)
+ break;
+ case PPSTREAM: // do something with obj->stream (ppstream *)
+ break;
+ case PPREF: // do something with obj->ref (ppref *)
+ break;
+ }
+
+More often then not you know exactly what type of object value is expected, in which case
+you may use one of the following macros::
+
+ // returns 1 if o->type is PPNULL
+ int ppobj_get_null(o) \
+
+ // if o->type is PPBOOL, sets int v to 0 or 1 and returns 1, 0 otherwise
+ int ppobj_get_bool(o, v)
+
+ // if o->type is PPINT, sets ppint v and returns 1, 0 otherwise
+ int ppobj_get_int(o, v)
+
+ // if o->type is PPINT and >= 0, sets ppuint v and returns 1, 0 otherwise
+ int ppobj_get_uint(o, v)
+
+ // if o->type is PPNUM or PPINT, sets ppnum v and returns 1, 0 otherwise
+ int ppobj_get_num(o, v)
+
+ // if o->type is PPNAME returns the name, NULL otherwise
+ ppname ppobj_get_name(o)
+
+ // if o->type is PPSTRING returns the string, NULL otherwise
+ ppstring ppobj_get_string(o)
+
+ // if o->type is PPARRAY returns the array, NULL otherwise
+ pparray * ppobj_get_array(o)
+
+ // if o->type is PPDICT returns the dict, NULL otherwise
+ ppdict * ppobj_get_dict(o)
+
+ // if o->type is PPSTREAM returns the stream, NULL otherwise
+ ppstream * ppobj_get_stream(o)
+
+ // if o->type is PPREF returns the reference, NULL otherwise
+ ppref * ppobj_get_ref(o)
+
+Note the coercion from integer to real number, but not reverse. In practise, whenever you expect a real number,
+you should also handle integer (eg. '1' used instead of '1.0').
+
+It is a common case that the object is given as an indirect reference, but what you actually
+want is not the reference, but the object referred by it. Here is a helper for it::
+
+ // if o->type is PPREF, returns what the reference points, otherwise returns o
+ ppobj * ppobj_rget_obj(o)
+
+Also every ``ppobj_get_*`` macro has ``ppobj_rget_*`` counterpart that makes a check
+for the expected type, but if the object is PPREF, it jumps to the target object.
+So for example ``ppobj_rget_dict(obj)`` will return dict if ``obj`` is of type PPDICT
+or if it is of type PPREF and ``obj->ref`` hosts an object of type PPDICT.
+
+Names
+-----
+
+PDF names are represented as ``ppname``.
+I find it convenient to have ``ppname`` type pretending ``const char *``. This allows to use ``ppname``
+in all C-style string functions like ``printf("%s", name)``.
+
+Be aware, however, that ``ppname`` is actually a C-structure. It is perfectly ok to cast ``ppname`` to ``const char *``::
+
+ ppname name;
+ ...
+ (const char *)name;
+
+But reverse is forbidden::
+
+ const char *cstr = "cstring";
+ ...
+ (ppname)cstr; // expect segmentation fault soon
+
+For convenient use in C, names are ``'\0'`` terminated. But to get the length of name better always use
+``ppname_size()`` macro. ``ppname`` object knows its size, don't use ``strlen()``::
+
+ size_t ppname_size(ppname name); // macro, returns length of name in bytes
+
+In current implementation names are not hashed anyhow, so name-to-name comparison is not smarter than ``memcmp()``.
+Use macros::
+
+ int ppname_is(ppname name, "literal"); // to compare ppname with C-literal string
+ int ppname_eq(ppname name, ppname other); // to compare ppname with a different name
+
+If you'll use ``pplib`` to parse contents streams, you may need to distinguish names from operators
+(more precisely executable names). Names in PDF are preceeded by '/', executable names aren't. In both
+cases PDF parser will produce ``ppname`` but can be distingushed with::
+
+ int ppname_exec(ppname name); // returns non-zero if name is executable
+
+Names are kept in their raw form, with possible PDF specific escapes (in text below we call it **encoded** form).
+Leading '/' is omitted, though. One may need a decoded name, with no PDF escapes.
+A pair of functions provides a simple interface to switch between those two forms::
+
+ ppname ppname_decoded (ppname name); // returns decoded (unescaped) form of the name
+ ppname ppname_encoded (ppname name); // returns encoded (escaped) form of the name
+
+In pretty most cases PDF names contains only letters (no special characters, no escapes), so decoded and encoded forms are identical.
+In that case both functions simply return the argument. It is ok to call ``ppname_decoded()`` on already decoded form
+and ``ppname_encoded()`` on already encoded form. Both forms are produced by PDF objects parser, so accessing ``ppname`` alter ego
+in whatever direction needs no extra decoding or allocation costs.
+
+String
+------
+
+PDF strings have the same internal construction as names, so most of names description above applies to strings as well.
+``ppstring`` is a typedef of ``const char *``, roughly ``'\0'`` terminiated C-string. To get the size of the string::
+
+ size_t ppstring_size(ppstring string); // macro, returns the length of the string in bytes
+
+Strings are provided in their raw form, preserving PDF specific escapes, but with no
+``()`` or ``<>`` delims. To distinguish plain strings from hex strings::
+
+ int ppstring_hex(ppstring string); // macro, returns non zero if hex string
+
+Or if you prefer::
+
+ switch (ppstring_type(string))
+ {
+ case PPSTRING_PLAIN: // literal string, surrounded by ``(`` and ``)`` in PDF
+ break;
+ case PPSTRING_BASE16: // hex string, surrounded by ``<`` and ``>`` in PDF
+ break;
+ case PPSTRING_BASE85: // base85 string surrounded by ``<~`` and ``~>`` in PDF
+ break;
+ }
+
+The last is actually Postscript specific, not used in PDF, but I think it might appear in contents streams...
+No matter how the string is given in PDF (plain or hex), here are two functions to
+switch between encoded and decoded strings forms::
+
+ ppstring ppstring_decoded (ppstring string); // returns decoded string possibly with PDF escapes
+ ppstring ppstring_encoded (ppstring string); // returns encoded string with no PDF escapes
+
+For hex strings, encoded form contains hex digits, while decoded form contains arbitrary bytes (the result of hex decoding).
+Plain strings usually contains printable ASCII characters, but they might contain any binary data.
+As with names, objects parser produces both forms. The raw form with PDF escapes (or raw hex form) is considered the main one.
+Eg. when you access ``obj->string`` you always get the encoded form. At any moment you can switch to its alter ego.
+
+No matter if the string is plain or hex, if its first two bytes (decoded) are UTF16 BOM, the string
+is considered unicode. ``ppstring`` object *knows* it is unicode or not::
+
+ switch (ppstring_utf(string))
+ {
+ case PPSTRING_UTF16LE: // unicode string, utf16le
+ break;
+ case PPSTRING_UTF16BE: // unicode string, utf16be
+ break;
+ default: // no unicode
+ }
+
+Or simply::
+
+ if (ppstring_utf(string) != 0) {
+ // handle unicode string
+ }
+
+If the string is unicode, BOM remains the part of the string -- ``pplib`` parser does not strip it.
+Unicode or not, encoded or decoded, strings are always C-arrays of bytes and ``ppstring_size()``
+always returns the size in bytes.
+
+Array
+-----
+
+PDF arrays are represented as ``pparray`` type, which is C-array of ``ppobj`` structures.
+To get the size::
+
+ size_t pparray_size(pparray *array) // macro, returns the number of array items
+
+To get ``ppobj *`` at a given index::
+
+ ppobj * pparray_at(array, index) // macro, returns ppobj * (no index check)
+ ppobj * pparray_get(array, index) // macro, returns ppobj * or NULL (with index check)
+ ppobj * pparray_get_obj (pparray *array, size_t index); // function equiv to pparray_get()
+
+Iterating over array elements::
+
+ pparray *array;
+ size_t index, size;
+ ppobj *obj;
+ for (size = pparray_size(array), pparray_first(array, index, obj); index < size; pparray_next(index, obj))
+ {
+ // do something with index and obj
+ }
+
+There is no magic first/next macros, just iteration over pointers. One could also use something like::
+
+ for (index = 0, size = array->size; index < size; ++index)
+ {
+ obj = pparray_at(array, index);
+ // do something with index and obj
+ }
+
+When getting values from array and expecting a result of known type, use one of the following::
+
+ int pparray_get_bool (pparray *array, size_t index, int *v); // get boolean value
+ int pparray_get_int (pparray *array, size_t index, ppint *v); // get ppint value
+ int pparray_get_uint (pparray *array, size_t index, ppuint *v); // get ppuint value
+ int pparray_get_num (pparray *array, size_t index, ppnum *v); // get ppnum value
+ ppname pparray_get_name (pparray *array, size_t index); // get ppname value
+ ppstring pparray_get_string (pparray *array, size_t index); // get ppstring value
+ pparray * pparray_get_array (pparray *array, size_t index); // get pparray * value
+ ppdict * pparray_get_dict (pparray *array, size_t index); // get ppdict * value
+ ppref * pparray_get_ref (pparray *array, size_t index); // get ppref * value
+
+As with ``ppobj_get_*`` suite, numeric types getters set the value of a given type and returns 1, if the type matches.
+Otherwise sets nothing and returns 0. Other getters return the value if the type matches, or NULL.
+
+Every function from ``pparray_get_*`` suite have its ``pparray_rget_*`` counterpart that
+that dereferences indirect objects (as explained for ``ppobj_rget_*`` getters). Note that
+there is no ``pparray_get_stream()`` function, as streams in PDF are always indirect.
+To get the stream from array use::
+
+ ppstream * pparray_rget_stream (pparray *array, size_t index);
+
+Dict
+----
+
+PDF dicts are represented as ``ppdict`` structure, which is C-array of ``ppobj`` with parallel
+C-array of ``ppname`` pointers. To get the size of a dict::
+
+ size_t ppdict_size(ppdict *dict) // macro, returns the number of key-val pairs
+
+To get the value at a given index (integer)::
+
+ ppobj * ppdict_at(ppdict *dict, index) // macro, no index check
+
+To get the name (key) at a given index::
+
+ ppname ppdict_key(ppdict *dict, index) // macro, no index check
+
+To iterate over dict key-val pairs::
+
+ ppdict *dict;
+ ppname *pkey;
+ ppobj *obj;
+
+ for (ppdict_first(dict, pkey, obj); *pkey != NULL; ppdict_next(pkey, obj))
+ {
+ // do something with *pkey and obj
+ }
+
+There is no magic in first/next macros, just iteration through keys and values lists pointers.
+For convenient iteration, a list of keys is terminated with NULL, so in the code above ``*pkey != NULL``
+is used as the loop condition. One may also iterate via indices::
+
+ ppdict *dict;
+ size_t index, size;
+ ppname key;
+ ppobj *obj;
+ for (index = 0, size = ppdict_size(dict); index < size; ++index)
+ {
+ key = ppdict_key(dict, index);
+ obj = ppdict_at(dict, index);
+ // do something with key and obj
+ }
+
+To get the object associated with a given name, use one of the following::
+
+ ppobj * ppdict_get_obj (ppdict *dict, const char *name);
+ int ppdict_get_bool (ppdict *dict, const char *name, int *v);
+ int ppdict_get_int (ppdict *dict, const char *name, ppint *v);
+ int ppdict_get_uint (ppdict *dict, const char *name, ppuint *v);
+ int ppdict_get_num (ppdict *dict, const char *name, ppnum *v);
+ ppname ppdict_get_name (ppdict *dict, const char *name);
+ ppstring ppdict_get_string (ppdict *dict, const char *name);
+ pparray * ppdict_get_array (ppdict *dict, const char *name);
+ ppdict * ppdict_get_dict (ppdict *dict, const char *name);
+ ppref * ppdict_get_ref (ppdict *dict, const char *name);
+
+Note that all getters accepts ``const char *`` as key, so it is ok to say::
+
+ ppdict_rget_dict(dict, "Resources");
+
+as well as::
+
+ ppdic_rget_dict(dict, name); // ppname name
+
+Every ``ppdict_get_*`` getter has ``ppdict_rget_*`` counterpart that dereferences
+indirect objects if necessary. Note that there is no ``ppdict_get_stream()`` function,
+but there is::
+
+ ppstream * ppdict_rget_stream (ppdict *dict, const char *name);
+
+So far dicts comes with no names mapping, so by-name dict accessors perform a linear search
+through the keys list. PDF dicts are usually small, so it is fast enough.
+Building names lookup for every dict in PDF makes no sense I think, as ``pplib`` applications
+will query just several dicts I guess.. However, some apps may extensively query
+resources, which may refer to hundreds of objects (eg. images). So some mapping for dicts
+is still considered.
+
+Stream
+------
+
+PDF streams are represented as ``ppstream`` objects. To get the stream dict::
+
+ ppdict * ppstream_dict(ppstream *stream) // macro
+
+To read the stream data::
+
+ uint8_t * ppstream_first (ppstream *stream, size_t *size, int decode);
+ uint8_t * ppstream_next (ppstream *stream, size_t *size);
+ void ppstream_done (ppstream *stream);
+
+Both ``first` and ``next`` functions return a chunk of stream data and sets the ``size`` of the chunk.
+``decode`` parameter tell the reader to decompress the stream (1) or return raw (0). A call to ``ppstream_next()``
+must be preceeded by ``ppstream_first()``. Once you're done with the stream, you have to call ``ppstream_done()``,
+no matter if the stream has been read to the end or not. The stream data iterator in use::
+
+ uint8_t *data;
+ size_t size;
+ ppstream *stream;
+ int decode = 1; // 1 - get decompressed, 0 - get raw
+
+ for (data = ppstream_first(stream, &size, decode); data != NULL; data = ppstream_next(stream, &size))
+ {
+ // do something with data and its size
+ }
+ ppstream_done(stream);
+
+Every subsequent iterator call invalidates the previous reader output, so you have to utilize the returned chunk
+of data just after you ot that. So the following is wrong::
+
+ data1 = ppstream_first(stream, &size, 1);
+ data2 = ppstream_next(stream, &size);
+ data3 = ppstream_next(stream, &size);
+ some_output(data1, size);
+ some_output(data2, size);
+
+The reader calls usually return the same pointer to internal buffer, just filled with a different data.
+``pplib`` allocates reasonably large buffer and fills that buffer on subsequent calls to the reader.
+
+If the source stream has no compression, using both ``decode == 1`` and ``decode == 0`` should give the same result.
+You can check if the stream is actually compressed with::
+
+ ppstream_compressed(stream) // macro, returns non zero if /Filter is present
+
+It might be necessary to load the entire stream data at once::
+
+ uint8_t * ppstream_all (ppstream *stream, size_t *size, int decode);
+
+If the initial buffer size is insufficient, it grows until the entire stream data is loaded. You must call
+``ppstream_done(stream)`` after using returned data.
+
+``ppstream_done()`` doesn't invalidate the stream object, it just closes its internal reader.
+The stream itself remains a valid object (eg. one can read it again if necessary),
+but the reader buffer is released. It is actually not freed but kept for future the reuse with that on some other stream,
+but you still need to mark it ready for reuse to avoid allocating a separate buffer for every stream you're going to read.
+
+Stream data readers will return ``NULL`` if you haven't close the previous reader process with ``ppstream_done()``. All below is wrong::
+
+ data1 = ppstream_all(stream, &size, 1);
+ data2 = ppstream_all(stream, &size, 1); // data2 == NULL
+ // or
+ data1 = ppstream_first(stream, &size, 1);
+ data2 = ppstream_first(stream, &size, 1); // data2 == NULL
+ // or
+ data1 = ppstream_first(stream, &size, 1);
+ data2 = ppstream_all(stream, &size, 1); // data2 == NULL
+
+To avoid unnecessary dependencies, ``pplib`` does not support image filters (``/DCT``, ``/JPX``, ``/JBIG``, ``/CCITT``).
+But it is ok to read the stream with ``decode`` set to 1 on such streams. ``pplib`` assumes that the image is the
+final/target stream form and just returns it as-is. Eg. in the case of JPEG (``/DCT`` filtered) image both calls should
+give the same results::
+
+ ppstream_all(jpegstream, &jpegsize, 0); // don't decode, return what's there
+ ppstream_all(jpegstream, &jpegsize, 1); // decode but found image filter, effectively the same
+
+A bit more about streams memory. As mentioned, ``pplib`` allocates buffers for stream readers. After ``ppstream_done()``,
+the stream no longer *owns* the buffer space. But the buffer may remain allocated, to be reused with future readers.
+``pplib`` keeps a pool of several buffers. This means, that when you use stream readers, ``pplib`` eats
+some memory (1MB or so) that is not freed, even if no streams are used. And even if you free all objects.
+If you suffer from this, you can optionally use a pair of functions::
+
+ void ppstream_init_buffers (void);
+ void ppstream_free_buffers (void);
+
+The first initializes buffers pool, unless done so far. Currently ``pplib`` cares of it before opening every stream reader,
+so it is not obligatory. The second frees a pool of buffers. The intended use is to call ``ppstream_init_buffers()`` once
+as kind of library initializer and to call ``ppstream_free_buffers()`` once, as the library finalizer.
+
+Filters
+-------
+
+In version v1.00 (20190916) ``ppstream`` API has been extended with filters information.
+``ppstream`` knows its filter(s) and keps it as ``stream->filter``::
+
+ // ppstream *stream;
+ ppstream_filter *info = &stream->filter;
+
+``ppstream_filter`` is the following structure::
+
+ typedef struct {
+ ppstreamtp *filters; // c-array of filter identifiers (enum integers)
+ ppdict **params; // c-array of ppdict pointers
+ size_t count; // number of filters, length of the arrays (typically 1)
+ } ppstream_filter;
+
+If ``count > 0`` then ``filters`` member is not NULL. Filters array keeps integer constants::
+
+ PPSTREAM_BASE16 /* /ASCIIHexDecode */
+ PPSTREAM_BASE85 /* /ASCII85Decode */
+ PPSTREAM_RUNLENGTH /* /RunLengthDecode */
+ PPSTREAM_FLATE /* /FlateDecode */
+ PPSTREAM_LZW /* /LZWDecode */
+ PPSTREAM_CCITT /* /CCITTFaxDecode */
+ PPSTREAM_DCT /* /DCTDecode */
+ PPSTREAM_JBIG2 /* /JBIG2Decode */
+ PPSTREAM_JPX /* /JPXDecode */
+ PPSTREAM_CRYPT /* /Crypt */
+
+Params array keeps corresponding filter parameters (``/DecodeParms``) if present. ``params`` member is not NULL
+if ``count > 0`` and the stream dict has ``/DecodeParms`` entry. Even if ``params`` is there,
+for every N-th filter, ``params[N]`` may be NULL (corresponding to PDF ``null``).
+
+``stream->filter`` keeps the source stream filter information, which may not correspond to the result of stream readers
+(``ppstream_first()``, ``ppstream_next()``, ``ppstream_all()``). The get the filters info relevant to the result from readers::
+
+ void ppstream_filter_info (ppstream *stream, ppstream_filter *info, int decode);
+
+The function fills ``ppstream_filter`` structure according to the expected result from stream readers (example 3 shows
+how to use it to reconstruct ``/Filter`` and ``/DecodeParms`` when copying the stream to some other PDF).
+
+To convert filter identifier (``ppstreamtp``) to a corresponding PDF filter name::
+
+ const char * ppstream_filter_name[];
+
+To covert ``ppname`` to filter identifier::
+
+ int ppstream_filter_type (ppname filtername, ppstreamtp *filtertype);
+ // returns 1 and sets filtertype if filtername is the proper filter name
+
+Additional information about the stream can be fetched from macros::
+
+ ppstream_compressed(stream) /* stream->flags & (PPSTREAM_FILTER|PPSTREAM_IMAGE) */
+ ppstream_filtered(stream) /* stream->flags & PPSTREAM_FILTER */
+ ppstream_image(stream) /* stream->flags * PPSTREAM_IMAGE */
+
+``stream->flags`` is a binary sum of the following::
+
+ PPSTREAM_FILTER /* set iff the stream filters list has one of: BASE16, BASE85, RUNLENGTH, FLATE, LZW */
+ PPSTREAM_IMAGE /* set iff the stream filters list has one of: CCITT, DCT, JBIG2, JPX */
+ PPSTREAM_ENCRYPTED /* set iff the stream is encrypted */
+ PPSTREAM_ENCRYPTED_OWN /* set iff the stream has own CRYPT filter */
+
+Note that ``PPSTREAM_COMPRESSED`` is not there any longer, use ``ppstream_compressed()`` instead.
+And there is some more, see ``ppapi.h``.
+
+Ref
+---
+
+Indirect objects are represented as ``ppref`` structure. To get the object that the
+reference refers to::
+
+ ppobj * ppref_obj(ppref *ref) // macro
+
+``ppref`` structure also keeps the reference number and version, a pointer to cross reference table it belongs
+to and others, but I guess you won't need anything but the referenced object. ``pplib`` parser resolves references
+on-fly. So if there is a dict with indirect objects::
+
+ <<
+ /Type /Page
+ /Resources 123 0 R
+ ...
+ >>
+
+the parser will produce ``ppdict`` with ``Resources`` key pointing the proper ``ppref *`` value.
+If you need more, access ``ppref`` members::
+
+ struct ppref {
+ ppobj object; // target object
+ ppuint number, version; // identifiers
+ size_t offset; // file offset (useless for you, may be zero for compressed objects)
+ ppuint length; // the length of the original object data
+ ppxref *xref; // cross reference table it belongs to
+ };
+
+
+XRef
+----
+
+Cross reference table is exposed as ``ppxref`` (incomplete type, you can only oprate on its pointer).
+To get top document xref::
+
+ ppxref * ppdoc_xref (ppdoc *pdf);
+
+To get previous (older) xref::
+
+ ppxref * ppxref_prev (ppxref *xref);
+
+To find an object of a given refnumber::
+
+ ppref * ppxref_find (ppxref *xref, ppuint refnumber);
+
+[Note: since pplib v0.98 in case of documents with incremental update, ``ppxref_find()`` returns
+the newest available version of a given object rather than the object in a given body.]
+
+PDF
+---
+
+PDF document is represented as ``ppdoc`` structure (incomplete type, you can only operate on its pointer).
+To load a document from file::
+
+ ppdoc * ppdoc_load (const char *filename);
+
+To load a document from memory data::
+
+ ppdoc * ppdoc_mem (const void *data, size_t size);
+
+The data is assumed to be a buffer allocated with ``malloc`` - it is freed when destroying ``ppdoc``.
+
+Both loaders returns ``NULL`` on failure.
+
+To free ``ppdoc`` and all objects it refers to::
+
+ void ppdoc_free (ppdoc *pdf);
+
+So far we haven't mention about any explicit object reclaimers. There are no dedicated ``free`` functions
+for other objects. You don't allocate or free objects yourself. ``ppdoc`` object is an owner of all
+beings it refers to. It also means that every object described so far is alive as long as the containing
+``ppdoc`` is alive.
+
+To access main PDF dicts::
+
+ ppdict * ppdoc_trailer(ppdoc *pdf); // returns top xref trailer dict
+ ppdict * ppdoc_catalog(ppdoc *pdf); // returns catalog referred from the trailer
+ ppdict * ppdoc_info(ppdoc *pdf); // returns info dict referred from the trailer
+
+To get the PDF version::
+
+ const char * ppdoc_version_string (ppdoc *pdf); // version string
+ int ppdoc_version_number (ppdoc *pdf, int *minor); // minor and major numbers
+
+To get the file size of the source PDF document::
+
+ size_t ppdoc_file_size (ppdoc *pdf);
+
+To get the number of objects in all xrefs::
+
+ ppuint ppdoc_objects (ppdoc *pdf);
+
+To get the approx usage of memory::
+
+ size_t ppdoc_memory (ppdoc *pdf, size_t *waste);
+
+Encryption
+----------
+
+``pplib`` handles encrypted (password protected) documents. If a document is encrypted, most of strings and streams are ciphered.
+In that form they are unreadable and rather useless, you can't even rewrite such strings/streams as-is to a different PDF output.
+It is a common practise to *protect* documents with an empty password. Such documents remain readable in Acrobat (just opens them without prompting
+for a password), but some features (eg. printing) may restricted by the application.
+
+When ``pplib`` detects encryption, it follows Acrobat approach and first tries an empty password. If it succeeds, ``pplib`` proceeeds normally, providing
+an access to decrypted strings and streams, as if they weren't ciphered. If the document is protected with non-empty password, ``pplib`` gives
+a way to provide a password and proceed. Until you provide a password, ``ppdoc`` object returned by ``ppdoc_load()`` function has all object wntries
+set to ``null``.
+
+After loading a document you should check encryption status with::
+
+ ppcrypt_status ppdoc_crypt_status (ppdoc *pdf);
+
+``ppcrypt_status`` (integer) may have the following values:
+
+ ``PPCRYPT_NONE`` - no encryption, go ahead
+ ``PPCRYPT_DONE`` - encryption present but password succeeded, go ahead
+ ``PPCRYPT_PASS`` - encryption present, need non-empty password
+ ``PPCRYPT_FAIL`` - invalid or unsupported encryption (eg. undocumented in pdf spec)
+
+If a password is needed, you can provide one with::
+
+ ppcrypt_status ppdoc_crypt_pass (ppdoc *pdf, const void *userpass, size_t userpasslength,
+ const void *ownerpass, size_t ownerpasslength);
+
+Well, yes, there are actually two passwords in encrypted documents. Relation between them is obscure to me, but enough
+to know that having one of them is enough to decrypt the document. If you know the password, you probably mean
+``userpass``, in which case you should put ``NULL`` as ``ownerpass``. The function returns ``PPCRYPT_DONE`` if the password
+succeeds and the previous status otherwise. Your custom loader function may look like that::
+
+ ppdoc *pdf;
+ pdf = ppdoc_load("file.pdf");
+ if (pdf == NULL)
+ return NULL;
+ switch (ppdoc_crypt_status(pdf))
+ {
+ case PPCRYPT_NONE:
+ case PPCRYPT_DONE:
+ return pdf;
+ case PPCRYPT_PASS:
+ if (ppdoc_crypt_pass(pdf, "dummy", 5, NULL, 0) == PPCRYPT_DONE ||
+ ppdoc_crypt_pass(pdf, NULL, 0, "dummy", 5) == PPCRYPT_DONE)
+ return pdf;
+ printf("sorry, password needed\n");
+ ppdoc_free(pdf);
+ return NULL;
+ case PPCRYPT_FAIL:
+ printf("sorry, encryption failed\n");
+ ppdoc_free(pdf);
+ return NULL;
+ }
+
+[If you get ``PPCRYPT_FAIL`` it might mean *I failed*, so treat as a bug.]
+
+If you'd like to know what permissions are given/restricted to encrypted document::
+
+ ppint ppdoc_permissions (ppdoc *pdf);
+
+Returned value can be queried with the following binary flags (you can verify with Acrobat *File -> Properties -> Security* tab)::
+
+ PPDOC_ALLOW_PRINT // printing
+ PPDOC_ALLOW_MODIFY // filling form fields, signing, creating template pages
+ PPDOC_ALLOW_COPY // copying, copying for accessibility
+ PPDOC_ALLOW_ANNOTS // filling form fields, copying, signing
+ PPDOC_ALLOW_EXTRACT // contents copying for accessibility
+ PPDOC_ALLOW_ASSEMBLY // (no effect)
+ PPDOC_ALLOW_PRINT_HIRES // (no effect)
+
+``pplib`` does absolutelly nothing with permissions, it cares only to decrypt the document. As mentioned, encryption applies to strings
+and streams. ``pplib`` decrypt strings when parsing document objects, so the result you get is *normal* (not ciphered).
+Streams are decrypted whenever you access them. Even if you ask for a raw stream data, you'll get a raw (compressed) stream, but decrypted.
+So except the check to ``ppdoc_crypt_status()``, you shouldn't bother about encryption.
+
+In encrypted documents most of streams are encrypted. To check if a given stream is encrypted::
+
+ ppstream_encrypted(stream) // macro, returns non-zero if encrypted
+
+Encryption is independent from compression, don't confuse with ``ppstream_compressed()``
+
+Pages
+-----
+
+Several helpers to deal with pages. To get the number of pages::
+
+ ppuint ppdoc_page_count (ppdoc *pdf);
+
+To access the root pages tree node::
+
+ ppref * ppdoc_pages(ppdoc *pdf);
+
+To get the page reference at a given index::
+
+ ppref * ppdoc_page (ppdoc *pdf, ppuint index);
+
+``index`` is a page number. First page has number 1. For index out of bounds ``ppdoc_page()`` returns NULL.
+Iterating over pages using index from 1 to ``ppdoc_page_count()`` and calling ``ppdoc_page()`` on each iteration
+would be suboptimal. Here is a dedicted iterator for this::
+
+ ppref * ppdoc_first_page (ppdoc *pdf);
+ ppref * ppdoc_next_page (ppdoc *pdf);
+
+The iterator in use::
+
+ ppdoc *pdf;
+ ppref *ref;
+ ppdict *dict;
+ int pageno;
+
+ pdf = ppdoc_load("file.pdf");
+ for (ref = ppdoc_first_page(pdf), pageno = 1; ref != NULL; ref = ppdoc_next_page(pdf), ++pageno)
+ {
+ dict = ppref_obj(obj)->dict; // take for granted it is a dict
+ // do something with the page dict
+ }
+
+Functions related to pages return ``ppref *`` ensured to contain dict object, so you don't need sanity
+type checks here.
+
+Contents
+--------
+
+PDF page contents can be given as a stream or array of streams. Here is a convenience iterator over page
+contents streams::
+
+ ppstream * ppcontents_first (ppdict *dict);
+ ppstream * ppcontents_next (ppdict *dict, ppstream *stream);
+
+A complete example of contents stream parser use is given below (example 2).
+But before we get there, we need to introduce ``ppcontext`` object. Conceptually,
+``ppcontext`` is an owner (memory handler) of objects created on demand (beyond the ``ppdoc``).
+So far used only with contents stream parser, which might produce quite some data that we want
+to release just after used. To create a new context::
+
+ pcontext * ppcontext_new (void);
+
+It initializes a new context and its internal memory heap, taking about 64kB on start. After that,
+the context is ready to produce objects (contents parsing functions below). Once objects produced
+from a given context are no longer needed::
+
+ void ppcontext_done (ppcontext *context);
+
+It restores the context to its initial state, as after ``ppcontext_new()``. It means that the context
+is ready to produce another bunch of beings (in the example below, all objects from the next page contents).
+Once the context is not needed anymore::
+
+ void ppcontext_free (ppcontext *context);
+
+Now, contents stream parser functions take the context as an argument. Iterator form of contents stream parser
+that allows to process the contents operator by operator::
+
+ ppobj * ppcontents_first_op (ppcontext *context, ppstream *stream, size_t *psize, ppname *pname);
+ ppobj * ppcontents_next_op (ppcontext *context, ppstream *stream, size_t *psize, ppname *pname);
+
+Returned ``ppobj *`` is a pointer to operands list. ``*psize`` is the number of operands on stack.
+The operator itself is stored as ``*pname``.
+
+To parse the entire contents stream at once with no stop at every operator::
+
+ ppobj * ppcontents_parse (ppcontext *context, ppstream *stream, size_t *psize);
+
+Returns probably quite long list of all parsed objects (operands and operatos) in one piece.
+The number of objects is stored to ``*psize``.
+
+[Contents may contain so called inline images, that breaks a simple scheme of operands / operator syntax::
+
+ BI <keyval pairs> ID <binary image data> EI
+
+Contents parser treats this genuine triplet as a single piece, producing two operands (dict and string)
+followed by ``EI`` operator name.]
+
+Boxes
+-----
+
+Boxes (rectangles) in PDF are roughly 4-number arrays, but with a special intent.
+``pplib`` provides a basic interface for these special arrays::
+
+ typedef struct {
+ ppnum lx, ly, rx, ry;
+ } pprect;
+
+This type is used only by helper functions - PDF parser is not aware of the rectangle type.
+To convert ``pparray`` to ``pprect``::
+
+ pprect * pparray_to_rect (pparray *array, pprect *rect); // returns rect or NULL
+
+In example::
+
+ pprect rect;
+ if (pparray_to_rect(array, &rect) != NULL)
+ ; // do something with rect
+
+To get some image bounding box::
+
+ pprect * ppdict_get_rect (ppdict *dict, const char *name, pprect *rect);
+ // eg. ppdict_get_rect(imagedict, "BBox", &rect)
+
+To get some page box::
+
+ pprect * ppdict_get_box (ppdict *dict, const char *name, pprect *rect);
+ // eg. ppdict_get_box(pagedict, "MediaBox", &rect)
+
+The later not only checks the pagedict, but also goes through parent page nodes.
+
+Transforms
+----------
+
+Transformations are given as 6-number arrays, but with a special intent.
+``pplib`` provides a basic interface for these special arrays::
+
+ typedef struct {
+ ppnum xx, xy, yx, yy, x, y;
+ } ppmatrix;
+
+This type is used only by helper functions - PDF parser is not aware of the matrix type.
+To convert ``pparray`` to ``ppmatrix``::
+
+ ppmatrix * pparray_to_matrix (pparray *array, ppmatrix *matrix);
+
+In example::
+
+ ppmatrix matrix;
+ if (pparray_to_matrix(array, &matrix) != NULL)
+ ; // do something with matrix
+
+To get the matrix from dict::
+
+ ppmatrix * ppdict_get_matrix (ppdict *dict, const char *name, ppmatrix *matrix);
+ // eg. ppdict_get_matrix(imagedict, "Matrix", &matrix)
+
+Errors handling
+---------------
+
+``pplib`` is not verbose, but might happen that it needs to log some error message, eg. when parsing
+of some PDF boject fails due to invalid offsets. By default, ``pplib`` prints the message to stdout, eg.::
+
+ invalid 123 0 R object at offset 123123
+
+To replace the default logger, you can provide your own::
+
+ void pplog_callback (pplogger_callback logger, void *alien);
+
+``pplogger_callback`` is a function::
+
+ void your_callback (const char *message, void *alien);
+
+In example, to redirect messages to stderr you may define a function::
+
+ void your_callback (const char *message, void *alien)
+ {
+ fprintf((FILE *)alien, "\nooops: %s\n", message);
+ }
+
+Then set the callback somewhere before loading documents::
+
+ pplog_callback(your_callback, stderr);
+
+(example 2 uses that).
+
+To set the default log messages prefix, eg. ``pplib:``, use::
+
+ int pplog_prefix (const char *prefix)
+
+Default is empty. The function succeeds if provided prefix is reasonably short (less then 32 bytes).

+<p><code class="docutils literal notranslate"><span class="pre">pplib</span></code> is a library for raw PDF access. It parses PDF documents and provides an interface to access document structures in C.</p>

+<h2>Types<a class="headerlink" href="#types" title="Permalink to this headline">¶</a></h2>
+<p><code class="docutils literal notranslate"><span class="pre">pplib</span></code> defines several C-types to represent PDF types:</p>
+<ul class="simple">
+<li><code class="docutils literal notranslate"><span class="pre">ppint</span></code> - signed integer (<code class="docutils literal notranslate"><span class="pre">int64_t</span></code>)</li>
+<li><code class="docutils literal notranslate"><span class="pre">ppnum</span></code> - real number (double)</li>
+<li><code class="docutils literal notranslate"><span class="pre">ppname</span></code> - PDF name</li>
+<li><code class="docutils literal notranslate"><span class="pre">ppstring</span></code> - PDF string</li>
+<li><code class="docutils literal notranslate"><span class="pre">pparray</span></code> - PDF array</li>
+<li><code class="docutils literal notranslate"><span class="pre">ppdict</span></code> - PDF dict</li>
+<li><code class="docutils literal notranslate"><span class="pre">ppstream</span></code> - PDF stream</li>
+<li><code class="docutils literal notranslate"><span class="pre">ppref</span></code> - PDF indirect reference</li>
+<li><code class="docutils literal notranslate"><span class="pre">ppobj</span></code> - a container of all above</li>
+</ul>
+<p>Among <code class="docutils literal notranslate"><span class="pre">ppint</span></code> and <code class="docutils literal notranslate"><span class="pre">ppnum</span></code>, we also use <code class="docutils literal notranslate"><span class="pre">ppuint</span></code> - unsigned integer (machine word, alias to <code class="docutils literal notranslate"><span class="pre">size_t</span></code>).</p>
+<p>Other API types:</p>
+<ul class="simple">
+<li><code class="docutils literal notranslate"><span class="pre">ppdoc</span></code> - PDF document</li>
+<li><code class="docutils literal notranslate"><span class="pre">ppxref</span></code> - cross-references table</li>
+<li><code class="docutils literal notranslate"><span class="pre">ppcontext</span></code> - … later</li>
+<li><code class="docutils literal notranslate"><span class="pre">pprect</span></code> - rectangle</li>
+<li><code class="docutils literal notranslate"><span class="pre">ppmatrix</span></code> - matrix</li>
+</ul>
+<p>Integer, number, name and string are treated as simple types.
+Names and strings are actually C-structures, but exposed to API as typedefs to <code class="docutils literal notranslate"><span class="pre">const</span> <span class="pre">char</span> <span class="pre">*</span></code>.
+Other types (array, dict, stream, reference, object container, xref, PDF) are C-structures,
+and you operate it their pointers. So when you declare a simple type variable you say:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">ppuint</span> <span class="n">u</span><span class="p">;</span>
+<span class="n">ppnum</span> <span class="n">n</span><span class="p">;</span>
+<span class="n">ppname</span> <span class="n">name</span><span class="p">;</span>
+<span class="n">ppstring</span> <span class="n">string</span><span class="p">;</span>
+<span class="o">...</span>
+</pre></div>
+</div>
+<p>And when you declare a compound type you operate on pointers:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">ppobj</span> <span class="o">*</span><span class="n">obj</span><span class="p">;</span>
+<span class="n">pparray</span> <span class="o">*</span><span class="n">array</span><span class="p">;</span>
+<span class="n">ppdict</span> <span class="o">*</span><span class="nb">dict</span><span class="p">;</span>
+<span class="n">ppstream</span> <span class="o">*</span><span class="n">stream</span><span class="p">;</span>
+<span class="n">ppref</span> <span class="o">*</span><span class="n">ref</span><span class="p">;</span>
+<span class="n">ppdoc</span> <span class="o">*</span><span class="n">pdf</span><span class="p">;</span>
+</pre></div>
+</div>
+<p>Some of those C-types are defined in library header <code class="docutils literal notranslate"><span class="pre">ppapi.h</span></code> (complete types). Some others are incomplete
+(eg. you can’t say <code class="docutils literal notranslate"><span class="pre">sizeof(ppdoc)</span></code> or <code class="docutils literal notranslate"><span class="pre">sizeof(ppxref)</span></code>). This is to avoid unnecesary dependencies in
+the header. [At some points it’s not clear to me what to hide and what to expose, will see.] The library itself
+uses <code class="docutils literal notranslate"><span class="pre">pplib.h</span></code> but for auxilary applications including a standalone <code class="docutils literal notranslate"><span class="pre">ppapi.h</span></code> header should be enough.</p>
+<p><code class="docutils literal notranslate"><span class="pre">pplib</span></code> was designed having <strong>read-only</strong> PDF access in mind. Even if some structure is completelly exposed,
+so that you can directly access its members, you should treat them as read-only. I don’t make them <code class="docutils literal notranslate"><span class="pre">const</span></code> because
+then all variable declarations would need to be <code class="docutils literal notranslate"><span class="pre">const</span></code>, which is annoying, and I’d need some trickery in the library
+internals to unconst. Besides, nothing is really const for C type casts.</p>

+<p>Note the coercion from integer to real number, but not reverse. In practise, whenever you expect a real number,
+you should also handle integer (eg. ‘1’ used instead of ‘1.0’).</p>
+<p>It is a common case that the object is given as an indirect reference, but what you actually
+want is not the reference, but the object referred by it. Here is a helper for it:</p>

+<p>If you’ll use <code class="docutils literal notranslate"><span class="pre">pplib</span></code> to parse contents streams, you may need to distinguish names from operators
+(more precisely executable names). Names in PDF are preceeded by ‘/’, executable names aren’t. In both
+cases PDF parser will produce <code class="docutils literal notranslate"><span class="pre">ppname</span></code> but can be distingushed with:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="nb">int</span> <span class="n">ppname_exec</span><span class="p">(</span><span class="n">ppname</span> <span class="n">name</span><span class="p">);</span> <span class="o">//</span> <span class="n">returns</span> <span class="n">non</span><span class="o">-</span><span class="n">zero</span> <span class="k">if</span> <span class="n">name</span> <span class="ow">is</span> <span class="n">executable</span>
+</pre></div>
+</div>
+<p>Names are kept in their raw form, with possible PDF specific escapes (in text below we call it <strong>encoded</strong> form).
+Leading ‘/’ is omitted, though. One may need a decoded name, with no PDF escapes.
+A pair of functions provides a simple interface to switch between those two forms:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">ppname</span> <span class="n">ppname_decoded</span> <span class="p">(</span><span class="n">ppname</span> <span class="n">name</span><span class="p">);</span> <span class="o">//</span> <span class="n">returns</span> <span class="n">decoded</span> <span class="p">(</span><span class="n">unescaped</span><span class="p">)</span> <span class="n">form</span> <span class="n">of</span> <span class="n">the</span> <span class="n">name</span>

+</pre></div>
+</div>
+<p>In pretty most cases PDF names contains only letters (no special characters, no escapes), so decoded and encoded forms are identical.
+In that case both functions simply return the argument. It is ok to call <code class="docutils literal notranslate"><span class="pre">ppname_decoded()</span></code> on already decoded form
+and <code class="docutils literal notranslate"><span class="pre">ppname_encoded()</span></code> on already encoded form. Both forms are produced by PDF objects parser, so accessing <code class="docutils literal notranslate"><span class="pre">ppname</span></code> alter ego
+in whatever direction needs no extra decoding or allocation costs.</p>

+<p>Strings are provided in their raw form, preserving PDF specific escapes, but with no
+<code class="docutils literal notranslate"><span class="pre">()</span></code> or <code class="docutils literal notranslate"><span class="pre"><></span></code> delims. To distinguish plain strings from hex strings:</p>

+}
+</pre></div>
+</div>
+<p>The last is actually Postscript specific, not used in PDF, but I think it might appear in contents streams…
+No matter how the string is given in PDF (plain or hex), here are two functions to
+switch between encoded and decoded strings forms:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">ppstring</span> <span class="n">ppstring_decoded</span> <span class="p">(</span><span class="n">ppstring</span> <span class="n">string</span><span class="p">);</span> <span class="o">//</span> <span class="n">returns</span> <span class="n">decoded</span> <span class="n">string</span> <span class="n">possibly</span> <span class="k">with</span> <span class="n">PDF</span> <span class="n">escapes</span>

+</pre></div>
+</div>
+<p>For hex strings, encoded form contains hex digits, while decoded form contains arbitrary bytes (the result of hex decoding).
+Plain strings usually contains printable ASCII characters, but they might contain any binary data.
+As with names, objects parser produces both forms. The raw form with PDF escapes (or raw hex form) is considered the main one.
+Eg. when you access <code class="docutils literal notranslate"><span class="pre">obj->string</span></code> you always get the encoded form. At any moment you can switch to its alter ego.</p>
+<p>No matter if the string is plain or hex, if its first two bytes (decoded) are UTF16 BOM, the string

+<p>So far dicts comes with no names mapping, so by-name dict accessors perform a linear search

+<p>To avoid unnecessary dependencies, <code class="docutils literal notranslate"><span class="pre">pplib</span></code> does not support image filters (<code class="docutils literal notranslate"><span class="pre">/DCT</span></code>, <code class="docutils literal notranslate"><span class="pre">/JPX</span></code>, <code class="docutils literal notranslate"><span class="pre">/JBIG</span></code>, <code class="docutils literal notranslate"><span class="pre">/CCITT</span></code>).

+<p>A bit more about streams memory. As mentioned, <code class="docutils literal notranslate"><span class="pre">pplib</span></code> allocates buffers for stream readers. After <code class="docutils literal notranslate"><span class="pre">ppstream_done()</span></code>,
+the stream no longer <em>owns</em> the buffer space. But the buffer may remain allocated, to be reused with future readers.
+<code class="docutils literal notranslate"><span class="pre">pplib</span></code> keeps a pool of several buffers. This means, that when you use stream readers, <code class="docutils literal notranslate"><span class="pre">pplib</span></code> eats
+some memory (1MB or so) that is not freed, even if no streams are used. And even if you free all objects.
+If you suffer from this, you can optionally use a pair of functions:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">void</span> <span class="n">ppstream_init_buffers</span> <span class="p">(</span><span class="n">void</span><span class="p">);</span>
+<span class="n">void</span> <span class="n">ppstream_free_buffers</span> <span class="p">(</span><span class="n">void</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>The first initializes buffers pool, unless done so far. Currently <code class="docutils literal notranslate"><span class="pre">pplib</span></code> cares of it before opening every stream reader,
+so it is not obligatory. The second frees a pool of buffers. The intended use is to call <code class="docutils literal notranslate"><span class="pre">ppstream_init_buffers()</span></code> once
+as kind of library initializer and to call <code class="docutils literal notranslate"><span class="pre">ppstream_free_buffers()</span></code> once, as the library finalizer.</p>

+<h2>Encryption<a class="headerlink" href="#encryption" title="Permalink to this headline">¶</a></h2>
+<p><code class="docutils literal notranslate"><span class="pre">pplib</span></code> handles encrypted (password protected) documents. If a document is encrypted, most of strings and streams are ciphered.
+In that form they are unreadable and rather useless, you can’t even rewrite such strings/streams as-is to a different PDF output.
+It is a common practise to <em>protect</em> documents with an empty password. Such documents remain readable in Acrobat (just opens them without prompting
+for a password), but some features (eg. printing) may restricted by the application.</p>
+<p>When <code class="docutils literal notranslate"><span class="pre">pplib</span></code> detects encryption, it follows Acrobat approach and first tries an empty password. If it succeeds, <code class="docutils literal notranslate"><span class="pre">pplib</span></code> proceeeds normally, providing
+an access to decrypted strings and streams, as if they weren’t ciphered. If the document is protected with non-empty password, <code class="docutils literal notranslate"><span class="pre">pplib</span></code> gives
+a way to provide a password and proceed. Until you provide a password, <code class="docutils literal notranslate"><span class="pre">ppdoc</span></code> object returned by <code class="docutils literal notranslate"><span class="pre">ppdoc_load()</span></code> function has all object wntries
+set to <code class="docutils literal notranslate"><span class="pre">null</span></code>.</p>
+<p>After loading a document you should check encryption status with:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">ppcrypt_status</span> <span class="n">ppdoc_crypt_status</span> <span class="p">(</span><span class="n">ppdoc</span> <span class="o">*</span><span class="n">pdf</span><span class="p">);</span>
+</pre></div>
+</div>
+<p><code class="docutils literal notranslate"><span class="pre">ppcrypt_status</span></code> (integer) may have the following values:</p>
+<blockquote>
+<div><code class="docutils literal notranslate"><span class="pre">PPCRYPT_NONE</span></code> - no encryption, go ahead
+<code class="docutils literal notranslate"><span class="pre">PPCRYPT_DONE</span></code> - encryption present but password succeeded, go ahead
+<code class="docutils literal notranslate"><span class="pre">PPCRYPT_PASS</span></code> - encryption present, need non-empty password
+<code class="docutils literal notranslate"><span class="pre">PPCRYPT_FAIL</span></code> - invalid or unsupported encryption (eg. undocumented in pdf spec)</div></blockquote>
+<p>If a password is needed, you can provide one with:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">ppcrypt_status</span> <span class="n">ppdoc_crypt_pass</span> <span class="p">(</span><span class="n">ppdoc</span> <span class="o">*</span><span class="n">pdf</span><span class="p">,</span> <span class="n">const</span> <span class="n">void</span> <span class="o">*</span><span class="n">userpass</span><span class="p">,</span> <span class="n">size_t</span> <span class="n">userpasslength</span><span class="p">,</span>

+</pre></div>
+</div>
+<p>Well, yes, there are actually two passwords in encrypted documents. Relation between them is obscure to me, but enough
+to know that having one of them is enough to decrypt the document. If you know the password, you probably mean
+<code class="docutils literal notranslate"><span class="pre">userpass</span></code>, in which case you should put <code class="docutils literal notranslate"><span class="pre">NULL</span></code> as <code class="docutils literal notranslate"><span class="pre">ownerpass</span></code>. The function returns <code class="docutils literal notranslate"><span class="pre">PPCRYPT_DONE</span></code> if the password
+succeeds and the previous status otherwise. Your custom loader function may look like that:</p>

+<p><code class="docutils literal notranslate"><span class="pre">pplib</span></code> does absolutelly nothing with permissions, it cares only to decrypt the document. As mentioned, encryption applies to strings

+Streams are decrypted whenever you access them. Even if you ask for a raw stream data, you’ll get a raw (compressed) stream, but decrypted.
+So except the check to <code class="docutils literal notranslate"><span class="pre">ppdoc_crypt_status()</span></code>, you shouldn’t bother about encryption.</p>

+contents streams:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">ppstream</span> <span class="o">*</span> <span class="n">ppcontents_first</span> <span class="p">(</span><span class="n">ppdict</span> <span class="o">*</span><span class="nb">dict</span><span class="p">);</span>

+</pre></div>
+</div>
+<p>A complete example of contents stream parser use is given below (example 2).
+But before we get there, we need to introduce <code class="docutils literal notranslate"><span class="pre">ppcontext</span></code> object. Conceptually,
+<code class="docutils literal notranslate"><span class="pre">ppcontext</span></code> is an owner (memory handler) of objects created on demand (beyond the <code class="docutils literal notranslate"><span class="pre">ppdoc</span></code>).
+So far used only with contents stream parser, which might produce quite some data that we want
+to release just after used. To create a new context:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">pcontext</span> <span class="o">*</span> <span class="n">ppcontext_new</span> <span class="p">(</span><span class="n">void</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>It initializes a new context and its internal memory heap, taking about 64kB on start. After that,
+the context is ready to produce objects (contents parsing functions below). Once objects produced
+from a given context are no longer needed:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">void</span> <span class="n">ppcontext_done</span> <span class="p">(</span><span class="n">ppcontext</span> <span class="o">*</span><span class="n">context</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>It restores the context to its initial state, as after <code class="docutils literal notranslate"><span class="pre">ppcontext_new()</span></code>. It means that the context
+is ready to produce another bunch of beings (in the example below, all objects from the next page contents).
+Once the context is not needed anymore:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">void</span> <span class="n">ppcontext_free</span> <span class="p">(</span><span class="n">ppcontext</span> <span class="o">*</span><span class="n">context</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Now, contents stream parser functions take the context as an argument. Iterator form of contents stream parser
+that allows to process the contents operator by operator:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">ppobj</span> <span class="o">*</span> <span class="n">ppcontents_first_op</span> <span class="p">(</span><span class="n">ppcontext</span> <span class="o">*</span><span class="n">context</span><span class="p">,</span> <span class="n">ppstream</span> <span class="o">*</span><span class="n">stream</span><span class="p">,</span> <span class="n">size_t</span> <span class="o">*</span><span class="n">psize</span><span class="p">,</span> <span class="n">ppname</span> <span class="o">*</span><span class="n">pname</span><span class="p">);</span>

+<h2>Errors handling<a class="headerlink" href="#errors-handling" title="Permalink to this headline">¶</a></h2>
+<p><code class="docutils literal notranslate"><span class="pre">pplib</span></code> is not verbose, but might happen that it needs to log some error message, eg. when parsing
+of some PDF boject fails due to invalid offsets. By default, <code class="docutils literal notranslate"><span class="pre">pplib</span></code> prints the message to stdout, eg.:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">invalid</span> <span class="mi">123</span> <span class="mi">0</span> <span class="n">R</span> <span class="nb">object</span> <span class="n">at</span> <span class="n">offset</span> <span class="mi">123123</span>
+</pre></div>
+</div>
+<p>To replace the default logger, you can provide your own:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">void</span> <span class="n">pplog_callback</span> <span class="p">(</span><span class="n">pplogger_callback</span> <span class="n">logger</span><span class="p">,</span> <span class="n">void</span> <span class="o">*</span><span class="n">alien</span><span class="p">);</span>

+<p><code class="docutils literal notranslate"><span class="pre">pplogger_callback</span></code> is a function:</p>

+</pre></div>

+<p>In example, to redirect messages to stderr you may define a function:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">void</span> <span class="n">your_callback</span> <span class="p">(</span><span class="n">const</span> <span class="n">char</span> <span class="o">*</span><span class="n">message</span><span class="p">,</span> <span class="n">void</span> <span class="o">*</span><span class="n">alien</span><span class="p">)</span>

+<span class="p">}</span>
+</pre></div>
+</div>
+<p>Then set the callback somewhere before loading documents:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">pplog_callback</span><span class="p">(</span><span class="n">your_callback</span><span class="p">,</span> <span class="n">stderr</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>(example 2 uses that).</p>
+<p>To set the default log messages prefix, eg. <code class="docutils literal notranslate"><span class="pre">pplib:</span></code>, use:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="nb">int</span> <span class="n">pplog_prefix</span> <span class="p">(</span><span class="n">const</span> <span class="n">char</span> <span class="o">*</span><span class="n">prefix</span><span class="p">)</span>
+</pre></div>
+</div>
+<p>Default is empty. The function succeeds if provided prefix is reasonably short (less then 32 bytes).</p>

Every output value is taken from its higher (left) bits. In a special case of bits-per-component equal 1, we buffer all
pixel bits and use XOR to compute bits difference between pixels. I've excerpted that trick from poppler, but I'm not
really sure if it works any better, especially when the number of components per pixel is 1. In that case we do a hard
