2017-04-27Include required system headers.Tor Andersson
2017-04-13Change generated files to be C instead of headers.Tor Andersson
Remove AdobeCA.p7c from autogenerated files. Just include the array in the source. Simplifies makefile dependencies and makes the sizes of each bit of data easier to look at. It also paves the way for eventually using objcopy to create binary objects for the fonts instead of needing to use hexdump.
2017-03-22Rename fz_putc/puts/printf to fz_write_*.Tor Andersson
Rename fz_write to fz_write_data. Rename fz_write_buffer_* and fz_buffer_printf to fz_append_*. Be consistent in naming: fz_write_* calls write to fz_output. fz_append_* calls append to fz_buffer. Update documentation.
2017-03-21Replace fontdump, bin2hex and cquote with one tool: hexdump.Tor Andersson
Still need specialty tools for namedump and cmapdump.
2016-12-27Strip extraneous blank lines.Tor Andersson
2016-11-22Fix const compiler warning.Sebastian Rasmussen
2016-11-17Rename openssl flags to libcrypto.Sebastian Rasmussen
Only libcrypto is used to do checking of digital signatures. The SSL library openssl is never used.
2016-11-14Make fz_buffer structure private to fitz.Robin Watts
Move the definition of the structure contents into new fitz-imp.h file. Make all code outside of fitz access the buffer through the defined API. Add a convenience API for people that want to get buffers as null terminated C strings.
2016-10-18Avoid checking argument to fz_drop_*()/fz_free().Sebastian Rasmussen
As fz_drop_*()/fz_free() all must handle NULL.
2016-07-08Use fz_keep_imp and fz_drop_imp for all reference counting.Tor Andersson

2015-08-27Support several levels of incremental xrefPaul Gardiner
This fixes bug #696123 by allowing multiple signatures each to be written to the document in a separate incemental update. Add count num_incremental_sections to keep track of the number of incremental sections. Add xref_base, which can be set between 0 and num_incremental_sections inclusive to access different versions of the document. Add disallow_new_increments flag that stops new incremental sections being provoked by the creation of an xref stream. Move the unsaved_sigs list from the document structure to the xref structure. With this commit in place, the lists will never grow beyond length one, but we've maintained the list structure in case other cases need supporting in the future. Add an end offset field to the xref structure, so that during completion of signatures the document length of the various incremental versions of the document are available. Factor out functions for storing unsaved signatures and for checking if an object is an unsaved signature. Do deep copy of objects that require the holding of several versions.
2015-05-15Support pdf files larger than 2Gig.Robin Watts
If FZ_LARGEFILE is defined when building, MuPDF uses 64bit offsets for files; this allows us to open streams larger than 2Gig. The downsides to this are that: * The xref entries are larger. * All PDF ints are held as 64bit things rather than 32bit things (to cope with /Prev entries, hint stream offsets etc). * All file positions are stored as 64bits rather than 32. The implementation works by detecting FZ_LARGEFILE. Some #ifdeffery in fitz/system.h sets fz_off_t to either int or int64_t as appropriate, and sets defines for fz_fopen, fz_fseek, fz_ftell etc as required. These call the fseeko64 etc functions on linux (and so define _LARGEFILE64_SOURCE) and the explicit 64bit functions on windows.

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_*.
2014-02-14Add function for creating form fields (widgets)Paul Gardiner
This feature is being implemented mostly for the purpose of permitting the addition to a page of invisible signatures. Also change pdf_create_annot to make freshly created annotations printable by default.
