-% ================================ Objects ================================ %
-
-% We keep track of PDF objects using the following PostScript variables:
-%
-% Generations (string): Generations[N] holds 1+ the current
-% generation number for object number N. (As far as we can tell,
-% this is needed only for error checking.) For free objects,
-% Generations[N] is 0.
-%
-% Objects (array): If object N is loaded, Objects[N] is the actual
-% object; otherwise, Objects[N] is an executable integer giving
-% the file offset of the object's location in the file. If
-% ObjectStream[N] is non-zero then Objects[N] contains the index
-% into the object stream instead of the file offset of the object.
-%
-% ObjectStream (array): If object N is in an object stream then
-% ObjectStream[N] holds the object number of the object stream.
-% Otherwise ObjectStream[N] contains 0. If ObjectStream[N]
-% is non-zero then Objects[N] contains the index into the object
-% stream.
-%
-% GlobalObjects (dictionary): If object N has been resolved in
-% global VM, GlobalObjects[N] is the same as Objects[N]
-% (except that GlobalObjects itself is stored in global VM,
-% so the entry will not be deleted at the end of the page).
-%
-% IsGlobal (string): IsGlobal[N] = 1 iff object N was resolved in
-% global VM. This is an accelerator to avoid having to do a
-% dictionary lookup in GlobalObjects when resolving every object.

- % Its possible for us to end up here with a valid file. The way we work is to read the
- % stream and tokenise all the objects, but that assumes there will be delimiters or
- % whitespace between each object in the stream. We can easily think of cases where
- % that is not true; eg two consecutive numbers 123 456 would be tokenised as a
- % single number with the value 123456.
- % In this case we can use the approach below to read each object individually and
- % that will define the correct number of objects. After we've collected all the
- % objects we'll check the number of objects recovered again, and see if there
- % are still too few. We should probably raise an error in that case, but lets wait
- % until we see a case.
-
- % Having too many objects in an ObjStm is not illegal, dumb but not illegal. We can
- % recover from this, but its complicated. The extra object could be any of the ones
- % from the stream, the only way to find out is to process each object individually.
- % Unfortunately, my attempts to come up with a version of .pdfrun which only tokenised
- % one object got rapidly bogged down. So a new approach was needed.
- %
- % The idea is simple; turn the underlying file into a ReusableStream, then we can
- % reposition it. Build an array of the object offsets, reposition the file to the
- % start of each object in turn. For all except the last object, create a sub file
- % using SubFileDeocde with an empty string, and an EODCount which is the difference
- % between the offset of this object and the offset of the next.
- % For the last object we just read from the offset to the end of the stream.
- %
- % Then call .pdfrun on that sub file, or the main stream, which will tokenise all the
- % objects from that point onwards. Then discard all but the first object read.
- %
- % The complications arise from the fact that we need to end up with the objects on
- % the stack, in the right order, preceded by a mark, a count, and an array containing
- % all the object numbers.
-
- % First, discard everything we read up to now; we can reuse the 'mark' which was placed
- % by the preceding code to do this, as long as we remember to replace that 'mark'.
- % Handily this will leave the count and the array which contains the object numbers in place.

- %% case of Bug #696690 the /N value is correct, and the profile is wrong, in the case
- %% of Bug #696120 the /N value is incorrect and the profile is correct.
- %% We 'suspect' that Acrobat uses the fact that Bug #696120 is a pure image to detect
- %% that the /N is incorrect, we can't be sure whether it uses the profile or just uses
- %% the /N to decide on a device space. What we now do is; If the /N and device profile
- %% number of components don't match, we assume the device profile is correct and patch
- %% /N to be the same as the profile (see /ICCBased-resolve), but we save the original
- %% value of /N in /OrigN. In setcolor, if the space is a genuine ICCBased space
- %% (not a replacement for a device profile) we call set_dev_color which will actually
- %% exercise the profile. If that fails we return an error. Here we run setcolor in a
- %% stopped context, and if it fails we check to see if there is a /OrigN (ths occurs
- %% only if the /N was different to the number of components in the profile). If there
- %% is a /OrigN then prefer that to the profile, otherwise they agreed, so just use
- %% /N and select a device space. If we can't select a device space with the correct
- %% number of components, give up and throw an error. See also 'Cdict' in pdf_ops.ps.

- % Normally when dealing with recursion we would put a dictionary on the stack, store the

- % We also don't usually know the object number of a Form, we just get given its name
- % so we need a new routine to return the object number. This is because the parent XObject
- % might reference teh object by one name, while the child references it by another, we
- % can't permit clashes.

-% This dictionaty encapsulates all that is needed to generate pagelabel pdfmarks.
-%
-% This is provided by Leon Bottou for the benefit of the djvudigital device
-% which is a device developed and maintained outside of Artifex, and which is
-% not a contributed device.
-%
-% This device does not cope with the method used by pdfwrite to pass the pagelabels
-% number tree as a 'blob' of data, but requires that the page labels be passed using
-% a PAGELABEL pdfmark.
-%
-% We don't want to do that with pdfwrite because there is no mechanism in pdfmark syntax
-% to pass a tree, which means we'd have to laboriously disassemble the pdfmarks for the
-% page labels and rebuild a number tree for it. This would mean pattern matching each
-% string passed via PAGELABEL to see if it could be defined as a continuation
-% of the preceding string, uing prefixes. Its much easier for us just to pass the tree.
-%
-% Note that this code simply translates the PageLabels Number tree into a number of
-% individual PAGELABEL pdfmarks, if used for pdfwrite this would result in a number
-% tree which consists solely of leaf nodes, where each node has a string for its label.
-% This can be considerably more verbose than the shorthand possible with a Page Label

- % at the time we run the annotations is the same as when we ran the page, secondly in order
- % to empty the font cache before we run the annotations.
- %
- % Bug #700096 an annotation uses Helvetica but doesn't embed it, however the page *does*
- % use an embedded Helvetica, which is subset and not prefixed as such. For this file to
- % render correctly we must not use the font from the page, but must find a replacement.
- % However the file for Bug #695897 has a page which uses two versions of the same font,
- % one embedded, one not. In order for *that* file to render correctly we *must* use the
- % embedded font as a substitute for the missing font. So we divorce the fonts used
- % for the page from the fonts used for Annotations, this allows both files to work as
- % expected.
- %
- % We also need a countdictstack, so that we can check the dictionaries on the dictioanry
- % stack after we run the page contents, and 'end' an extra ones before we try to restore
- % otherwise we might try to restore back to a point before one of those dictionaries existed.

-% Set up color space substitution for a page. Invocations of this procedure
-% must be bracketed by the save/restore operation for the page, to avoid
-% unintended effects on other pages.
-%
-% If any color space substitution is used, and the current color space is a
-% device dependent color space, make sure the current color space is updated.
-% There is an optimization in the setcolorspace operator that does
-% nothing if both the current and operand color spaces are the same. For
-% PostScript this optimization is disabled if the UseCIEColor page device
-% parameter is true. This is not the case for PDF, as performance suffers
-% significantly on some PDF files if color spaces are set repeatedly. Hence,
-% if color space substitution is to be used, and the current color space
-% is a device dependent color space, we must make sure to "transition" the
-% current color space.

- %% This section is to deal with the horrible pair of files in Bug #696690 and Bug #696120
- %% These files have ICCBased spaces where the value of /N and the number of components
- %% in the profile differ. In addition the profile in Bug #696690 is invalid. In the
- %% case of Bug #696690 the /N value is correct, and the profile is wrong, in the case
- %% of Bug #696120 the /N value is incorrect and the profile is correct.
- %% We 'suspect' that Acrobat uses the fact that Bug #696120 is a pure image to detect
- %% that the /N is incorrect, we can't be sure whether it uses the profile or just uses
- %% the /N to decide on a device space. What we now do is; If the /N and device profile
- %% number of components don't match, we assume the device profile is correct and patch
- %% /N to be the same as the profile (see /ICCBased-resolve), but we save the original
- %% value of /N in /OrigN. In setcolor, if the space is a genuine ICCBased space
- %% (not a replacement for a device profile) we call set_dev_color which will actually
- %% exercise the profile. If that fails we return an error. Here we run setcolor in a
- %% stopped context, and if it fails we check to see if there is a /OrigN (ths occurs
- %% only if the /N was different to the number of components in the profile). If there
- %% is a /OrigN then prefer that to the profile, otherwise they agreed, so just use
- %% /N and select a device space. If we can't select a device space with the correct
- %% number of components, give up and throw an error. See also /last-ditch-bpc-csp

-% even if we do not need to rebuild a PDF file.
