2018-06-22Keep copy of decoded utf8 text string in pdf_obj.Tor Andersson
Removes the need to alloc/free text strings in the API, allowing for simple functions like pdf_dict_get_text_string.
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.
2018-01-28Bug 698942: Don't complain about external URLs being unknown.Sebastian Rasmussen
2017-09-20gl: Scroll to link coordinates when following links.Tor Andersson
Also save link coordinates in outline nodes.
2017-07-06fz_var() variables must be initialized before fz_try.Sebastian Rasmussen
2017-04-27Include required system headers.Tor Andersson
2017-04-11Bug 697662: Support named actions to first/last/next/previous page.Sebastian Rasmussen
2017-03-01Add page lookup cache for faster link destination lookups in outlines.Tor Andersson
Loading outlines wants to look up all link destinations, and doing the normal link destination lookups triggers loading all page objects used. This means we need to parse a lot of objects, which can be quite slow. We can load the page tree faster by only looking at intermediate page tree nodes. If we load the page tree and create a reverse lookup table for use when loading the outline, we can speed up the time to run 'mutool show pdfref17.pdf outline' from 900ms to 100ms.
2016-11-21Harden viewers against failures when loading outlines.Tor Andersson
Ignore invalid page references in outlines. This was shown by a file that had [null 0 0 1] as a link dest. Attempting to parse that threw an error, which caused the whole outline load to fail.
2016-11-14Add/fix page coordinates to link targets.Tor Andersson
Correctly transformed target coordinates for PDF. Target coordinates for EPUB and HTML.
2016-10-28Clean up link destination handling.Tor Andersson
All link destinations should be URIs, and a document specific function can be called to resolve them to actual page numbers. Outlines have cached page numbers as well as string URIs.
2016-10-07pdf: Remove unneccessary document argument to pdf_to_utf8 etc.Tor Andersson
2015-10-02Reference count fz_outline struct.Robin Watts
2015-03-25Fix silly typoRobin Watts
2015-03-25Bug 695878: Add entry to fz_outline to indicate if outline entry is openRobin Watts
Adopt a (trivially modified) patch provided by Simon Reinhardt. When loading pdf outlines, if the 'Count' field is positive, the outline entry should be considered open.
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_*.
2014-01-06fix 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.
2013-08-24Support named destinations in remote link annotations.Sebastian Rasmussen
Previously there was a bug when parsing GoToR link annotations that had a named destination. mupdf incorrectly attempted to resolve the destination in the current document. Now the destination name is present in the link objects returned to the application so it can resolve any names for GoToR links in the remote document instead.
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.
