* Rename typedefs (breaks API)Grigori Goronzy2009-08-061-18/+18
| | | | | | 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.
* Clean up typedefs/structsGrigori Goronzy2009-07-281-1/+1
| | | | | Remove useless _s suffix from struct names and remove struct name where not needed (only the typedef'd struct is used). Clean up API headers.
* Fix rasterizer error handling (double free)Grigori Goronzy2009-07-221-1/+0
| | | | | | In case rasterizing a glyph is successful, but rasterizing its outline is not, do not free the glyph bitmap. It will be freed in cache cleanup later. Freeing it earlier leads to a double free.
* Merge glyph and outline bitmap betterGrigori Goronzy2009-07-121-1/+1
| | | | | | | | Use a different threshold for merging the outline and glyph and also adjust the merge amount. This fails to give complete transparency (and thus will yield slightly darker looking glyphs, usually), but avoids very ugly looking artefacts at the edge between border and glyph that were still prevalent.
* Redo border calculations for \be and \blurGrigori Goronzy2009-07-121-25/+28
| | | | | | | | | | The last commit related to this overdid it a bit -- in some cases, with \be5, for example, edges were visible on the outlines. Instead of using a linear function to map \be applications to border enlargement value, use a nonlinear function, a simple square root. This seems to work a lot better, while keeping the enlargement small. In addition, make it possible to use \be and \blur at the same time. \be is applied first.
* Message callback funtionalityGrigori Goronzy2009-07-111-9/+10
| | | | | | | | | | | 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 Goronzy2009-07-111-3/+3
| | | | | | 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.
* Move gaussian blur into bitmap handling codeGrigori Goronzy2009-07-101-0/+121
|
* Slight optimizations for \be, \blurGrigori Goronzy2009-07-101-4/+4
| | | | | | | Enlarge bitmap glyphs less for \be, this is especially effective for lots of \be applications. Also make sure that the gaussian blur buffers are only updated if gaussian blur is actually used for a particular glyph.
* shift_bitmap: do not rely on compiler optimizationsGrigori Goronzy2009-06-291-4/+4
| | | | Do not rely on the compiler for optimizing a division into a shift.
* Subpixel accurate shadow renderingGrigori Goronzy2009-06-291-1/+56
| | | | | | | | | Shadows are handled different from glyph and outline. A shadow is the sum of glyph and outline bitmap; therefore shifting to the correct subpixel amount before rasterization is out of the question. Instead, the bitmap is shifted by its subpixel amount after being built from shadow and glyph. The bitmap cache was extended for this.
* Include ass_utils.h instead of mputils.hGrigori Goronzy2009-06-271-1/+1
|
* Rename various non-static functionsGrigori Goronzy2009-06-271-6/+8
| | | | | Rename a few functions to avoid symbol clashes. Clean up mputils.h.
* Rename mp_msg to ass_msgGrigori Goronzy2009-06-271-3/+3

* Reindent all source code.greg2009-06-201-253/+275
| | | | | | | | | | | | | | | 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

* If (has outline) blur(outline) else blur(glyph).eugeni2008-08-071-1/+2
| | | | | | | | | | | If there is an outline, the glyph itself should not be blurred. Keeps the border between glyph and outline clear (unblurred), which is probably how it should be.

* Partial fix for semitransparent glyph outlines.eugeni2006-11-131-1/+1
| | | | | | | | | | | | | This fix removes semitransparent area (less then pixel width) between glyph and it's outline. Instead, it makes them overlap a little. It usually looks much better this way. Complete fix seems impossible with the current output format (single color alpha bitmaps). The right way is to blend both glyph and outline into one bitmap so that 2 pixels with 50% transparency produce a fully solid one. This requires RGBA bitmap output from libass. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@20890 b3059339-0415-0410-9bf9-f77b7e298cf2
