2015-04-20Remove typo entries in names.txt list.Tor Andersson
2015-04-06Update mutool subtools to use PDF_NAME_xxx rather than "xxx".Robin Watts
2015-03-24Rework handling of PDF names for speed and memory.Robin Watts
Currently, every PDF name is allocated in a pdf_obj structure, and comparisons are done using strcmp. Given that we can predict most of the PDF names we'll use in a given file, this seems wasteful. The pdf_obj type is opaque outside the pdf-object.c file, so we can abuse it slightly without anyone outside knowing. We collect a sorted list of names used in PDF (resources/pdf/names.txt), and we add a utility (namedump) that preprocesses this into 2 header files. The first (include/mupdf/pdf/pdf-names-table.h, included as part of include/mupdf/pdf/object.h), defines a set of "PDF_NAME_xxxx" entries. These are pdf_obj *'s that callers can use to mean "A PDF object that means literal name 'xxxx'" The second (source/pdf/pdf-name-impl.h) is a C array of names. We therefore update the code so that rather than passing "xxxx" to functions (such as pdf_dict_gets(...)) we now pass PDF_NAME_xxxx (to pdf_dict_get(...)). This is a fairly natural (if widespread) change. The pdf_dict_getp (and sibling) functions that take a path (e.g. "foo/bar/baz") are therefore supplemented with equivalents that take a list (pdf_dict_getl(... , PDF_NAME_foo, PDF_NAME_bar, PDF_NAME_baz, NULL)). The actual implementation of this relies on the fact that small pointer values are never valid values. For a given pdf_obj *p, if NULL < (intptr_t)p < PDF_NAME__LIMIT then p is a literal entry in the name table. This enables us to do fast pointer compares and to skip expensive strcmps. Also, bring "null", "true" and "false" into the same style as PDF names. Rather than using full pdf_obj structures for null/true/false, use special pointer values just above the PDF_NAME_ table. This saves memory and makes comparisons easier.
2015-02-03Update URW fonts.Tor Andersson
Add the new URW base fonts that include greek and cyrillic scripts. These new fonts remove the need for DroidSans as a generic fallback font.
2014-05-29Fix 694093: add vertical variant of CJK fallback font.Tor Andersson
Replace the DroidSansFallback TTF files with a TTC that has two fonts: The original and a copy where the OpenType 'vert' substitution lookup has been pre-applied by copying the uniXXXX.vert glyph data to uniXXXX.
2014-05-11Optimize UniXXX CMap files.Tor Andersson
Split common parts into separate CMap files and include them with usecmap. This reduces the size of the compiled in CMap resources from 3Mb to 2Mb.
2014-05-10Fix 694085: Add UTF8 and UTF32 CMaps.Tor Andersson
Remove obsolete Adobe-Japan-2 based CMaps.
