There is always some approximation error.)Īnother minor difference in the specification seems to be that ttf flavoured OpenType fonts may address the same glyph with several code points. (Also note that neither cubic nor quadratic Bézier splines may exactly reproduce a circle. (Historically, quadratic Bézier curves have been used for the ‘legacy’ TrueType format cubic Bézier curves have come from a PostScript background.) Cubic Béziers are potentially more accurate (every quadratic Bézier curve can be exactly reproduced with a cubic Bézier curve) but may be approximated with smaller segmented sequences of quadratic Béziers. otf style fonts use cubic Bézier splines. ttf style fonts use quadratic Bézier splines whereas. The main difference between both flavours being that. ttf font files may look as if they are in legacy ANSI-Windows TrueType format, whereas in fact they may be full featured OpenType fonts. (See OpenType in Wikipedia – actually, this is more accurately pronounced in the German version.) ttf may denote fonts in the OpenType format. Please note that when file endings are converned, both.
