yes, the freetype library (and i guess you using it) is highly optimized for font rendering. sure thing, cairo path rendering is fast as well, but it is not as specialized for just font rendering as freetype, therefore, i have no doubts that it will be slower. >>>> -- >>>> Best regards, >>>> Igor Stasenko. >>> >>> >> >> >> >> -- >> Best regards, >> Igor Stasenko. > > -- Best regards, Igor Stasenko.
