Class TBGRAVectorizedFontRenderer
Unit
Declaration
type TBGRAVectorizedFontRenderer = class(TBGRACustomFontRenderer)
Description
Font renderer using vectorized fonts and with effects.
TBGRAVectorizedFontRenderer class works like other font renderers, i.e., it can be assigned to the FontRenderer property. You can use it in two different modes :
if you supply a directory, it will look for *.glyphs files in it to load fonts
if you don't supply a directory, fonts will be vectorized from the system
If provides effect like TBGRATextEffectFontRenderer (outline and shadow) but that difference is that the font is always vectorized whereas TBGRATextEffectFontRenderer will use bitmap rendering when possible.
