<div>I tested about how anti-alias options affect text drawing performance.</div>
<div> </div>
<div>I used cairo_font_options_set_antialias and CAIRO_ANTIALIAS_NONE, CAIRO_ANTIALIAS_GRAY, CAIRO_ANTIALIAS_SUBPIXEL.</div>
<div> </div>
<div>But measured time of drawing text for CAIRO_ANTIALIAS_NONE & CAIRO_ANTIALIAS_GRAY was almost same!</div>
<div> </div>
<div>I think these options affect CGContextSetShouldAntialias, CGContextSetShouldSmoothFonts, but I can't find definitions of these functions.</div>
<div> </div>
<div>If CGContextSetShouldAntialias, CGContextSetShouldSmoothFonts are set to TRUE/FALSE, are they affect to performance much?</div>
