+About:
+~~~~~~
+`subfont' program renders antialiased fonts for mplayer using freetype library.
+Should work with TrueType, Type1 and any other font supported by libfreetype.
+
+Goals:
+ - internationalization: supports any 8 bit encoding (uses iconv).
+ - nice look: creates glyph `shadows' using algorithm derived from gaussian blur (slow!).
+
+
+Note:
+~~~~~
+Starting x position of each char and the bitmap width is aligned to multiple of 8
+(required for under-development MMX renderer).
+
+
+Usage:
+~~~~~~
+Usage: subfont encoding ppem font [alphaFactor [minAlpha [radius]]]
+ Program creates 3 files: font.desc, <encoding>-a.raw, <encoding>-b.raw.
+ You should append font.desc.tail (desc for OSD characters by a'rpi & chass) to font.desc,
+ and copy font.desc and all *.raw files to ~/.mplayer/font/ directory.
+
+ encoding must be 8 bit encoding, like iso-8859-2.
+ To list encodings available on your system use iconv -l.
+ ppem Font size in pixels (e.g. 24).
+ font Font file path. Any format supported by freetype library (*.ttf, *.pf?, *).
+ alphaFactor Alpha map scaling factor (default is 1.0), float.
+ minAlpha Alpha map minimum value (default is 1.0, max is 255), float.
+ radius Alpha map blur radius (default is 6 pixels), integer.
+
+
+Example:
+~~~~~~~~
+make
+./subfont iso-8859-2 20 verdana.ttf
+cat font.desc.tail >> font.desc
+cp font.desc *.raw ~/.mplayer/font/

+; Mplayer subtitle font description file - HighreS ONE
+; font created by a'rpi & chass
+; .desc created by chass & atmosfear
+; -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+;
+;
+; This file contains the data for Mplayer to build up the font
+; table from the bitmap files. These fonts are used for the OSD
+; (On Screen Display) and for the subtitles.
+;
+;
+; A few words for the novice user about the fonts:
+; -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+;
+; Mplayer uses antialiased bitmap fonts, which look far better
+; then the TTF rendering used by other players. A letter consists
+; of two main parts: the Bitmap and the Alpha chanel. The bitmap
+; is what you see on the screen, and the Aplha chanel makes the
+; Font fade smoothly ito the background. And in this font we use
+; the alpha to get a smooth black outline of the letters, which
+; makes them visible even on white areas of the movie.
+;
+; Mplayer needs at least two seperate 8bit/pixel format bitmap
+; files and a .desc file to be able to use the font. One of the
+; files is the bitmap the other is the alpha. The .desc (like this
+; one) gives Mplayer the information needed to convert a bitmap
+; to characters. But the .desc allows to use more bitmap and alpha
+; files: this feature is useful when one wants to add local language
+; support for the subtitles.
+;
+; -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+;
+; ABOUT THE .DESC
+;
+; [1],File layout: the file consists of several sections,
+; the sections are marked like [XXX] where XXX is the section
+; name. The three main sections:
+;
+; [info]: gives general information about the font, like the
+; version of the .desc, the author's name and general
+; rendering options like kerning.
+;
+; [files] & [characters] : they go togeather, they describe
+; the place of characters in the bitmap.
+; Up to 16 is allowed per .desc
+;
+; [2],The variables:
+;
+; [info]
+; name string name of the font, and misc information
+; desc int Version of this file
+; spacewidth int num of pixels for #32
+; charspace int the distance between chars

+; [character]
+; string int int the positon of a character
+;
+;

+; and 16 alpha channels).
