* fontselect: implement a coretext font providerStefano Pigozzi2015-07-101-1/+3
| | | | | | | | | | | | | | | Fontconfig is known to be very slow on OS X and Windows, this has to do with the extremely prohibitive cache times (which are getting even longer with latest versions of Fontconfig). This commits starts to address the problem by using CoreText on OS X to load the font data. The commit uses the simplest possible approach to load all of the data in memory and then use it to match. This causes a somewhat slow startup time (around ~400ms on my i7) but it is already better than waiting *minutes* for Fontconfig to cache the fonts data. A later commit will improve the speed of the match by using a hybrid approach that lazy loads in the libass database only the necessary fonts.
* Custom font matching and font sourcesGrigori Goronzy2015-07-101-4/+3
| | | | | | | Implement a simple font sorter (FontSelector) and an interface to deal with multiple font sources (FontProvider). Unfinished business, but works for the most part. Currently the only implemented FontProvider uses fontconfig.
* Implement cascade gaussian blurDr.Smile2015-07-041-2/+2
| | | | | | | | | | That's complete version with SSE2/AVX2 assembly. Should be much faster than old algorithm even in pure C. Algorithm description can be found in this article (PDF): https://github.com/MrSmile/CascadeBlur/releases Close #9

* Switch to virtual function tableDr.Smile2015-06-261-3/+3
| | | | | | | | | | Use one pointer to table of functions instead of scattered bunch of function pointers. Different versions of these tables can be constructed in compile time. Also, bitmap memory alignment now depends only on SSE2/AVX2 support and is constant for every width. That simplifies code without noticeable performance penalty.

* Revert "shaper: add UCDN support"Grigori Goronzy2012-10-151-1/+1
| | | | | | | | This reverts commit 840ce4c2d9381e340c3239d104933fea85fff3e5. Harfbuzz added UCDN support much quicker than I thought and the latest release 0.9.5 contains UCDN already, so we don't need it in libass anymore.
* shaper: add UCDN supportGrigori Goronzy2012-10-011-1/+1
| | | | | | Add explicit support for UCDN, without relying on any HarfBuzz integration. This finally allows easy usage of HarfBuzz without glib, ICU, or some other big bloated library!
* Provisional bidi and shaping supportGrigori Goronzy2011-07-061-1/+2
| | | | | | | | | | | | | | Adds fully working bidirectional text and simple shaping support. The following works: - bidirectional text according to the Unicode Bidirectional Algorithm - simple shaper for mirrored forms (brackets, etc.) according to rule L4 of the Unicode Bidirectional Algorithm - reordering into visual order with correct line wrapping However, the implementation certainly needs efficiency improvements (caching, less malloc'ing), a proper shaper (HarfBuzz) needs to be hooked up and various bugs with karaoke and positioning need to be fixed.

* Version bump0.9.10Grigori Goronzy2010-08-061-2/+2
| | | | | Increment shared library revision (due to API additions) and autoconf version.

* Replace strtod with locale-independent strtodGrigori Goronzy2010-01-051-1/+1
| | | | | | | | | strtod respects the locale and in some locales, the decimal separator is not a point, leading to parsing errors in tags like \pos(23.4,5), which are perfectly valid. As there isn't a really portable way to use a particular locale just for one call to strtod, reimplement it. The implementation was taken from the 1.8 branch of Ruby.
* Refactor: move event parsing code into separate fileGrigori Goronzy2009-09-011-1/+2
| | | | | Move all code related to parsing event lines and processing override tags into a separate file (ass_parse.c).

* Replace string defines with real stringsGrigori Goronzy2009-07-111-1/+1
| | | | | | Instead of referencing string defines from help_mp.h, use the strings directly in ass_msg. Consequently, help_mp.h is useless and can be deleted.
* Implement drawing mode (\p)Grigori Goronzy2009-07-061-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Finally implement the drawing mode, which allows drawing of custom vector graphics. Drawings are intercepted in ass_render_event; a hash of the drawing string is generated which is then used for looking up drawings and bitmaps of drawings in the cache. The drawings itself are "fake" glyphs. They are created by parsing the simple drawing description language, evaluating the curves described (lines, cubic beziers and/or a special kind of b-splines) and creating vector outlines. Afterwards, these drawings are (with a few exceptions, e.g. ascender/descender) exactly handled like regular glyphs. Support for vector clippings is still missing, but otherwise the implementation should be complete and compatible with VSFilter. The libass integration of the drawing parsing/processing code is still a bit sketchy and should be refactored. History: WIP: Drawing mode infrastructure WIP: Drawing tokenizer WIP: Parse drawing tokens, call evaluators WIP: Bezier/b-spline evaluator WIP: Final pieces for the drawing mode WIP: Heavy modifications to the drawing parser/tokenizer WIP: Dynamic outline memory allocation WIP: Drawing position fixes WIP: more drawing position fixup (similar to VSFilter now) WIP: Lots of cleanup and fixes for drawings. WIP: Drawing mode integration into ass_render_event
* Restrict symbols exported in the DSOGrigori Goronzy2009-06-291-0/+1
| | | | | | Only export those symbols into the shared object which are defined in the API (ass.h). A file libass.sym which contains a list of symbols was added and libtool configured to use it.
* Incorporate mputils.c into ass_utils.cGrigori Goronzy2009-06-271-3/+3
| | | | | | Move helper functions originating from MPlayer into ass_utils.c. Remove some debugging code that is #if 0'ed for ages now. Delete mputils.c and mputils.h and remove them from the build system.
* Add autotools infrastructure.greg2009-06-181-0/+14
