Re: [ft] bold problem with some fonts
Now I have a question about problem in bold rendering with some font, for example VLGothic font (http://dicey.org/vlgothic/). Attached is a font file which contains just the zero glyph of this font.

[ft] Testing new LCD rendering mode
Hi, I tested new libXft LCD Filtering patch and I got some screenshots to show too :-) http://cekirdek.pardus.org.tr/~ismail/tmp/knode-old-lcd-rendering.png shows the rendering with old LCD rendering patch, its all good there. http://cekirdek.pardus.org.tr/~ismail/tmp/knode-new-lcd-filtering.png shows the rendering with new LCD filtering patch, notice that the blurriness of the font makes it look bad especially when its bold, also notice there are color fringes which looks like the case for vanilla libXft + enabling subpixel hinting. Test Environment: 8pt Tahoma, 96 dpi I downloaded libXft-2.1.7 and applied patch libXft-2.1.7-lcd-filter-2.patch . Thoughts? P.S: Example application used is KNode.

Did you enable the bytecode interpreter in FreeType for the second example ? It doesn't seem so.

Freetype library did not change between tests ( I am actually just installing old libXft testing, installing new libXft testing ), so I don't think thats the problem but I agree it just looks like that indeed.

They're clearly different, look at the shapes of the 2 or 6, especially the horizontal stems in these glyphs. I think I understand now. I forgot to mention that you should enable medium or full hinting in your fonts preference dialog. That's because light hinting will now always invoke the auto-hinter (with the exception of fonts which require the unpatented hinter to load properly, e.g. MingLiU). I believe it should remove the difference you see. If not, send more screenshots :-) Regards, - David Turner - The FreeType Project (www.freetype.org) For reference I applied the following patch to Freetype sources before building.

Re: [ft-devel] Z/OS status
BTW, how are PS fonts handled on z/OS? Or, more general, how is PostScript handled on z/OS? Since PS is plain text normally, it could be EBCDIC also. And another follow-up: What about BDF and PCF? The former are pure text files, and the latter could be different too (in case they are based on EBCDIC text files). Do you know a document which covers fonts on z/OS and how they are stored and processed?

Re: [ft-devel] Rendering problem with 'y' character
Attached patch shows a rendering problem with 'y' character with Tahoma font (in python and system ). Notice that top-left part of y looks cropped. Dpi is 96, and font size is 9 pts. I only see the problem when italic text is used. Which tahoma font have you used? I only have normal and bold, but no slanted version. Does anyone know if this is a problem in KDE/Qt or a known problem? And how to debug this better? Can you reproduce the bad behaviour with ftview?

Re: [ft-devel] Z/OS status
Is there a possibility for the z/OS compiler to select the encoding of an input file? This would be the easiest solution. There is, but this doesn't completely work. It only covers cases where they may be string literals in the code which are expected to be in ascii. It still leaves open the possibility of there being algorithmic problems (there are, for example, functions called things like utf8_to_ascii and so on -- clearly they are broken on an EBCDIC system, regardless of the code page you use to compile the code). I don't find this a satisfactory solution. ___ Freetype-devel mailing list Freetype-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/freetype-devel
Re: [ft-devel] Z/OS status

Re: [ft-devel] Rendering problem with 'y' character
