2018-04-25Check in generated CMap source.Tor Andersson
Created with the 'scripts/runcmapdump.sh' script.
2018-04-24Remove need for namedump by using macros and preprocessor.Tor Andersson
Add a PDF_NAME(Foo) macro that evaluates to a pdf_obj for /Foo. Use the C preprocessor to create the enum values and string table from one include file instead of using a separate code generator tool.
2017-07-21Fix 698210: Remove superfluous recursion check in pdf_load_embedded_cmap.Tor Andersson
We already mark and check the usecmap entry where it is loaded.
2017-04-27Include required system headers.Tor Andersson
2017-04-27Use fz_snprintf.Tor Andersson
2016-12-08Fix incorrect recursive object marking.Robin Watts
We use pdf_mark_obj/pdf_unmark_obj to catch cycles when traversing PDF structures. In some cases we were failing to actually test the return code, making it pointless.
2016-09-01pdf: Load/open streams by indirect reference object when possible.Tor Andersson
2016-07-06pdf: Drop generation number from public interfaces.Tor Andersson
The generation number is only needed for decryption, and is assumed to be zero or irrelevant for all other uses. Store the original object number and generation in the xref slot, so that we can decrypt them even when the objects have been renumbered, without needing to pass the original object number around through the stream loading APIs.
2016-06-08Move to using size_t for all mallocs.Robin Watts
This has knock on effects in the store. fix
2016-06-06Minimize the number of CMaps built in to the ones listed in the spec.Tor Andersson
Omitting the unlisted UTF-8 and UTF-32 CMaps saves ~1M. Omitting the unlisted other CMaps saves ~200k. Define CJK_CMAPS=0 to skip all CMaps. Define EXTRA_CMAPS=1 to include the various other CMaps. Define UTF8_CMAPS=1 and UTF32_CMAPS to include the UTF-8 and UTF-32 CMaps.
2016-04-27Fix 696649: remove fz_rethrow_message calls.Tor Andersson
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.
2015-02-17Add ctx parameter and remove embedded contexts for API regularity.Tor Andersson
Purge several embedded contexts: Remove embedded context in fz_output. Remove embedded context in fz_stream. Remove embedded context in fz_device. Remove fz_rebind_stream (since it is no longer necessary). Remove embedded context in svg_device. Remove embedded context in XML parser. Add ctx argument to fz_document functions. Remove embedded context in fz_document. Remove embedded context in pdf_document. Remove embedded context in pdf_obj. Make fz_page independent of fz_document in the interface. We shouldn't need to pass the document to all functions handling a page. If a page is tied to the source document, it's redundant; otherwise it's just pointless. Fix reference counting oddity in fz_new_image_from_pixmap.
2015-02-17Rename fz_close_* and fz_free_* to fz_drop_*.Tor Andersson
Rename fz_close to fz_drop_stream. Rename fz_close_archive to fz_drop_archive. Rename fz_close_output to fz_drop_output. Rename fz_free_* to fz_drop_*. Rename pdf_free_* to pdf_drop_*. Rename xps_free_* to xps_drop_*.
2014-05-22Load the usecmap directives recursively for builtin CMaps.Tor Andersson
Fixes bug introduced in commit 1679c1e7a89ae62260fd84ce55c6bef376c6e6ba: Optimize UniXXX CMap files.
2014-05-13Use code space ranges when remapping ToUnicode CMaps.Tor Andersson
2014-05-10Fix 694698: Support 32-bit values in CMaps.Tor Andersson
Increasing the existing data structure to 32-bit values would bloat the data tables too much. Simplify the data structure and use three separate range tables for lookups -- one with small 16-bit to 16-bit range lookups, one with 32-bit range lookups, and a final one for one-to-many lookups. This loses the range-to-table optimization we had before, but even with the extra ranges this necessitates, the total size of the compiled binary CMap data is smaller than if we were to extend the previous scheme to 32 bits.
2014-01-06fix various MSVC warningsSimon Bünzli
Some warnings we'd like to enable for MuPDF and still be able to compile it with warnings as errors using MSVC (2008 to 2013): * C4115: 'timeval' : named type definition in parentheses * C4204: nonstandard extension used : non-constant aggregate initializer * C4295: 'hex' : array is too small to include a terminating null character * C4389: '==' : signed/unsigned mismatch * C4702: unreachable code * C4706: assignment within conditional expression Also, globally disable C4701 which is frequently caused by MSVC not being able to correctly figure out fz_try/fz_catch code flow. And don't define isnan for VS2013 and later where that's no longer needed.
2013-12-23Bug 694770: Fix typo in error message.Robin Watts
Thanks to Makoto Fujiwara for spotting this.
2013-06-27Move to using a flags bit rather than "Dirty" dict entries.Robin Watts
Correct the naming scheme for pdf_obj_xxx functions.
2013-06-25Rid the world of "pdf_document *xref".Robin Watts
For historical reasons lots of the code uses "xref" when talking about a pdf document. Now pdf_xref is a separate type this has become confusing, so replace 'xref' with 'doc' for clarity.
