2016-10-24When not preserving stext whitespace, only emit space character.Sebastian Rasmussen
Previously both a space character and the original whitespace character were emitted.
2016-10-24When not preserving stext ligatures, remember actual character added.Sebastian Rasmussen
Previously, when the ligatures were not preserved, the ligature glyph itself was remembered but not each individual character it expanded to.
2016-10-24Bug 697226: Fix SEGV in Android viewer.Robin Watts
As we skip through pages very quickly, it is apparently possible to trigger a SEGV. Alex Talis has given a clear description of the problem on the bug, and proposed this solution. Essentially this tweaks our CancellableAsyncTask class to ensure that we do not destroy the cookie before it has finished being accessed.
2016-10-24Fix cluster timeouts with test file.Robin Watts
tests_private/pdf/sumatra/1297_-_interpolate_at_lower_resolutions.pdf times out in the cluster. This is due to us having empty t3 glyphs defined that define d1 rectangles that are wildly different to the default font bbox. Add code to spot that t3 glyphs are empty, and to use a tiny font bbox for them. (It might be nicer to drop the empty display lists, but then this produces knock on problems further on, where non-existent display lists lead to NULL pixmaps, which lead to us think that renders failed etc).
2016-10-24Bug 697234: Fix slow rendering.Robin Watts
fz_contains_rect was improperly implemented (the logic in the final test was reversed). This was causing us to use the font bbox for some t3 glyphs, resulting in massive bboxes, that could never be cached. Rerendering these each time was taking ages, even though there was nothing actually in them.

2016-10-18tiff: Cosmetic cleanup of code.Sebastian Rasmussen
In preparation for YCbCr support, rename some functions and make variable names more generic. Also remove fz_ prefix from static functions.

2016-10-16gif: Do not paste frame data if frame and image do not overlap.Sebastian Rasmussen
2016-10-16gif: Handle frames bigger than image correctly.Sebastian Rasmussen
The existing fix for bug 697161 introduced in commit 651c9f1d93c81c84deaf76debec0a30e54a67d7e was broken as frames would be constrained to the image size - 1. Now we decompress all available data, not suggesting an uncompressed size, but still checking the size after the uncomprsseion.

2016-10-14Drop all contexts the same way.Sebastian Rasmussen
* Handle multiple calls to fz_drop_colorspace_context() and fz_drop_font_context(). * Allow missing context in call to fz_drop_aa_context() and fz_drop_glyph_cache_context(). * Only drop font context objects when dropping the last reference. * Avoid unnecessary NULL checks.

Commit c2acdba7e9b72e18afdd3aa8dfdf66088b1ea1be mistakenly inverted the interpretation of samples for both both binary and ascii b/w PNM images when, at the time, there was only a mistake for ascii images.

2016-10-13Bug 696885: Handle subsampled components in openjpeg decoder wrapper.Robin Watts
Also add simple ycc to rgb conversion (stolen from Sebastian's code).
2016-10-12Optimise fz_new_buffer_from_image_as_png.Robin Watts
This function calls png_from_pixmap, an auxiliary function to do the work. This was done deliberately to allow us to make the optimisation of dropping the pixmap early if it is not required. This keeps the memory use down in the case when a color conversion is required. Sadly, I never appear to have made the trivial change to actually use it in this mode. Do that now.
2016-10-13crypt: Handle null pointer when dropping crypt object.Sebastian Rasmussen
Exposed by weird-jpx.pdf from bug 696885.

When caching the cmyk values used to generate a given rgb value, it is best to cache the values before processing.
2016-10-12Fix leak in fz_load_jpx_info.Robin Watts
2016-10-12Bug 697151: Pacify valgrind when reading padding while unpacking tilesSebastian Rasmussen
If e.g. an 18 x 11 PNG image used 1 bit depth and a single component the source data fed to fz_unpack_tile() would have padding bits at the end of each line of whole bytes, because 18 bits is not a multiple of 8. The optimized 1 component versions of fz_unpack_tile() for a bit depth of 1 deliberately read the padding when doing the table lookups, knowing that this does not matter because of the construction of the table. Valgrind is incapable of understanding this, so we provide some extra masking (used only in PACIFY_VALGRIND builds) that explicitly mask off the invalid bits.
