See PDF Reference, section 3.3 Filters. Pdftex has drivers for native
JPEG and PNG embedding, anything else can be embedded as long as it
comes inside a PDF file.
Type Compression Embedding
JPEG DCT... native: copy image relevant stream subset
PNG zlib native: uncompress + re-compress, or copy
TIFF LZW via PDF file
FAX CCITT via PDF file
JBIG2 JBIG2 via PDF file
JPX JPEG2000 via PDF file
