How can I compute the bounding box of a given string of text without loading its glyphs before?
A lot of people want to be able to compute the size in pixels of a simple string of text with minimal overhead. For example, that can be useful to draw centered text within a button. (to be continued…) IV.5 Which anti-aliasing algorithm is used by FreeType 2? The algorithm has been specifically designed for FreeType. It is based on ideas that were originally found in the implementation of the libArt graphics library to compute the exact pixel coverage of a vector image with absolutely no sub-sampling/filtering. However, these two implementations are radically distinct and use vastly different models. The FreeType 2 renderer is optimized specifically for rendering small complex shapes, like glyphs, at very high speed while using very few memory; while libArt shines at general shape/polygon processing, especially large ones. The FreeType 2 anti-aliasing renderer is indeed faster than the monochrome renderer for small character sizes (typically <20 pixels). The reason is that the monoch
