Bonjour Pierre, the difference in text height is explained by the fact that, until recently, a value of 0 for y_dpi in a call to FT_Set_Char_Size was incorrectly interpreted as the default resolution of 72dpi, instead of meaning "same as the horizontal resolution"
this means your code was doing FT_Set_Char_Size(face, size, size, 100, 72) in 2.2.x and FT_Set_Char_Size(face, size, size, 100, 100) in 2.3.4 and later the Ubuntu version uses the bytecode interpreter, hence the difference with the release version of 2.2.1 the 2.3.4 and CVS version should have identical rendering. I think that the image shown on the bottom right corner is incorrect, it looks like the one from 16pt instead of 20pt Hope this helps, - David Turner - The FreeType Project (www.freetype.org) first of all, the reason why the characters appear squished in the first two columns if because a value of y_dpi of 0 is interpreted as the default "72" in FT_Set_Char_Size On Thu, 26 Apr 2007 15:15:30 +0200, "Pierre" <[EMAIL PROTECTED]> said: > Hi, > > While trying to have a small example to reproduce a libGD recent bug > report (http://bugs.libgd.org/?do=details&task_id=76), I modified one > of the manual example to see how looks the default rendering across > the following versions: 2.2.1, 2.2.1-Ubuntu Feisty, 2.3.4 and CVS. > > Here is the result of the tests (modified source there too), using the > Verdana font (MS Core fonts): > > http://pierre.libgd.org/ft2/comparison.html > > Other examples (using libgd) are visible in the bug report directly. > > As reported in the gd bug, the differences are important.
