2016-10-05Simplify fz_new_type3_fontRobin Watts
Call fz_calloc rather than fz_malloc_array and then manually clearing.
2016-10-05Uncouple font shaper data from harfbuzz.Robin Watts
The fz_font structure now doesn't know anything about harfbuzz at all, it merely offers an abstract 'fz_shaper_data_t' entry.
2016-10-05Move fz_font definition to be private.Robin Watts
Move the definition of fz_font to be in a private header file rather than in the public API. Add accessors for specific parts of the structure and use them as appropriate. The font flags, and the harfbuzz records remain public. This means that only 3 files now need access to the font implementation (font.c, pdf-font.c and pdf-type3.c). This may be able to be improved further in future.
2016-09-27Fix typo in fz_valgrind_pixmapRobin Watts
Function exists purely for doing valgrind testing of pixmap definedness.

2016-09-27Bug 697152: jpeg: Use correct macro to get client data.Sebastian Rasmussen
In commit 6a8abce9603f69b57e407f0df4044be919f507d7 an agnostic memory handler was introduced for libjpeg. While this commit changed error_exit_dct() it forgot to make a similar change in error_exit().

2016-09-26Update OpenJPEG to the latest (git) version.Robin Watts
Part of the change in this code is to require opj_malloc and co. Sadly, opj_malloc and co do not take a context field, so a we need to wrap calls to openjpeg with a lock. I am reusing the freetype lock here for simplicity.

2016-09-23GProof: Fix typos in gs invocationRobin Watts
2016-09-23Fix leak in error case of pdf_add_stream.Robin Watts
2016-09-23Clean up annotation enum names.Tor Andersson
Put them in the PDF name space and separate words with underscores. Remove redundant namespace prefixes in java constants. Device.FLAG_MASK rather than Device.FZ_DEVFLAG_MASK. Use namespace for PDF annotation flag enum.
2016-09-23Check for buffer overflow in strtod ascii division.Tor Andersson
2016-09-23Fix warning: set but unused variable.Tor Andersson
2016-09-22GPROOF: Modify gs invocation.Michael Vrhel
If we get the print profile given as '<EMBEDDED>' then use the print profile (Output Intent) embedded in the file. If not, we continue to use the defaults if given the empty string, or the given file otherwise.
2016-09-22tools: Prefer fz_atof() to atof().Sebastian Rasmussen
2016-09-22GProof: When invoking gs, redirect gs stdio to local stderr.Robin Watts
For android this means it will go to our logging. This moves the code out of gs.
2016-09-22Bug 697015: Avoid object references vanishing during repair.Robin Watts
A PDF repair can be triggered 'just in time', when we encounter a problem in the file. The idea is that this can happen without the enclosing code being aware of it. Thus the enclosing code may be holding 'borrowed' references (such as those returned by pdf_dict_get()) at the time when the repair is triggered. We are therefore at pains to ensure that the repair does not replace any objects that exist already, so that the calling code will not have these references unexpectedly invalidated. The sole exception to this is when we replace the 'Length' fields in stream dictionaries with the actual lengths. Bug 697015 shows exactly this situation causing a reference to become invalid. The solution implemented here is to add an 'orphan list' to the document, where we put these (hopefully few, small) objects. These orphans are kept around until the document is closed.
2016-09-22Bug 697018: Avoid recursing infinitely on dicts in mutool info.Sebastian Rasmussen
2016-09-21fix the quotes fixfred ross-perry
2016-09-21Bug 697106: Mark 64bit constants as such.Robin Watts
Avoids gcc giving spurious warnings.
2016-09-21Gproof GS invocation: Only quote profile names if required.Robin Watts
We need to quote profile names if we use system, but not if we use the GS_API. Update the code to cope.
2016-09-21Update GPRF invocation of GSRobin Watts
Have both the GSAPI and non GSAPI invocations be identical. Remove the -rxx bit because it is not required when using -gWxH and -dFitPage. Add some simple debug code.
2016-09-20Fix Memento crashRobin Watts
When reallocing set the rawsize before attempting to write the post guard block.
2016-09-20Sync Memento with gs.Robin Watts
Including: Bug 697134: Tweak MEMENTO_GS_HACKS inclusion. Rather than rolling our own memset prototype in this case, use the one that gs provides. And, bug 697133: Fix typo in Memento. Causing a significant slowdown. Thanks to George Burgess IV for spotting this.
