2016-10-06Squash compiler warning.Robin Watts
font->name can never be NULL as it is an array.
2016-10-06Hide internals of fz_colorspaceRobin Watts
The implementation does not need to be in the public API.
2016-10-05Add a const to a lookup function.Robin Watts
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.

2016-09-21Bug 697106: Mark 64bit constants as such.Robin Watts
Avoids gcc giving spurious warnings.
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.
2016-09-20Avoid signed/unsigned warnings.Robin Watts
2016-09-19fz_store: Reap passes.Robin Watts
A few commits back, we introduced the fz_key_storable concept to allow us to cope with objects that were used both as values within the store and as parts of keys within the store. This commit worked, but showed up performance problems; when the store has several million PDF objects in it, bulk changes (such as dropping a display list or document) could trigger many passes across the store. We therefore introduce a mechanism to ameliorate this. These passes, now known as "reap passes", can be batched together using fz_defer_reap_start and fz_defer_reap_end. We trigger this start/end around display list dropping, and around PDF content stream processing. This should be fine, as deferral will be interrupted if we ever run our of memory during mallocing.

2016-09-16Bug 695988: Avoid sending image data multiple times.Robin Watts
If the same image is used repeatedly, then we currently send the data again and again. Instead, send each image as a reusable symbol and reuse it as required. This reduces the size of the output by over 50% for the example file, but unfortunately results in the example file killing both Firefox and Edge when we attempt to load it. The file seems entirely valid though, and this is a saving on sane files. There is a #define that can be made to revert to the old behaviour (SVG_SEND_REPEATED_IMAGES).
