/* A small technical note regarding automatic hinting in order to */ |
/* clarify this module interface. */ |
/* */ |
/* An automatic hinter might compute two kinds of data for a given face: */ |
/* */ |
/* - global hints: Usually some metrics that describe global properties */ |
/* of the face. It is computed by scanning more or less */ |
/* aggressively the glyphs in the face, and thus can be */ |
/* very slow to compute (even if the size of global */ |
/* hints is really small). */ |
/* */ |
/* - glyph hints: These describe some important features of the glyph */ |
/* outline, as well as how to align them. They are */ |
/* generally much faster to compute than global hints. */ |
/* */ |
/* The current FreeType auto-hinter does a pretty good job while */ |
/* performing fast computations for both global and glyph hints. */ |
/* However, we might be interested in introducing more complex and */ |
/* powerful algorithms in the future, like the one described in the John */ |
/* D. Hobby paper, which unfortunately requires a lot more horsepower. */ |
/* */ |
/* Because a sufficiently sophisticated font management system would */ |
/* typically implement an LRU cache of opened face objects to reduce */ |
/* memory usage, it is a good idea to be able to avoid recomputing */ |
/* global hints every time the same face is re-opened. */ |
/* */ |
/* We thus provide the ability to cache global hints outside of the face */ |
/* object, in order to speed up font re-opening time. Of course, this */ |
/* feature is purely optional, so most client programs won't even notice */ |
/* it. */ |
/* */ |
/* I initially thought that it would be a good idea to cache the glyph */ |
/* hints too. However, my general idea now is that if you really need */ |
/* to cache these too, you are simply in need of a new font format, */ |
/* where all this information could be stored within the font file and */ |
/* decoded on the fly. */ |
