* Rename typedefs (breaks API)Grigori Goronzy2009-08-061-3/+3
| | | | | | Rename all typedefs from the convention foo_bar_t, which can possibly conflict with POSIX types, to FooBar (and ASS_FooBar for public API typedefs). Fix formatting and stray comments while at it.
* Clamp clip rectangle to frame sizeGrigori Goronzy2009-07-211-0/+1
| | | | | Make sure the clip rectangle is inside the screen boundaries. Idea by Evgeniy Stepanov.
* Message callback funtionalityGrigori Goronzy2009-07-111-4/+9
| | | | | | | | | | | Introduce functionality for providing a message callback that is used for passing messages to the controlling application instead of simply printing them to standard output. The function pointer to the callback is stored in the ass_library_t instance. ass_msg needs access to it, so in many places the library instance needs to be passed around now. The default behavior is the old one: messages of MSGL_INFO or lower are printed to the standard output, prefixed with "[ass]".
* Replace string defines with real stringsGrigori Goronzy2009-07-111-2/+0
| | | | | | 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 Goronzy2009-07-061-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Incorporate mputils.c into ass_utils.cGrigori Goronzy2009-06-271-0/+28
| | | | | | 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.
* Reindent all source code.greg2009-06-201-29/+37
| | | | | | | | | | | | | | | Reindent complete source code (*.c, *.h) with indent, the exact command line being: indent -kr -i4 -bap -nut -l76 *.c *.h From now on, new code should use (more or less) K&R style, only spaces and no tabs, 4 spaces indent width. Avoid long lines. Fix function declaration pointer spacing. Remove spaces that were added to many function declarations by indent, like some_func(foo_t * bar). Fix indenting of macros in ass.c

* Support fractional arguments for some override tags.eugeni2009-02-271-0/+1
| | | | | | | Done by parsing all integers as doubles first and then converting them to the nearest integer. Patch by Grigori G (greg chown ath cx). git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@28752 b3059339-0415-0410-9bf9-f77b7e298cf2
* Speak of libass instead of MPlayer in the libass license headers.diego2008-05-141-4/+4
| | | | | | | | We already use LIBASS_ prefixes for the multiple inclusion guards. Thus libass can be considered separate enough to warrant this. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@26770 b3059339-0415-0410-9bf9-f77b7e298cf2
