Re: [Fonts]New versions of mkfontscale and FreeType 2 backend
Thanks for the report and the suggestions. RG It looks better then I added this line by hand: RG MINGLIU.TTC -dynalab-MingLiU-medium-r-normal--0-0-0-0-m-0-big5-0 Yu Shao has just suggested to me the following heuristic for CJK fonts: an encoding is supported by the font if fewer than 2% of the glyphs are missing. I'm going to implement this scheme, and Big-5 encodings should be properly generated in the next version. RG The spacing value 'm' still will cause delay with rxvt. Don't know why. :) There's an optimisation (hack) for charcell (as opposed to monospaced) fonts in the FreeType backend. The delay you're seeing is what happens when we don't apply said hack. RG How about using os2-ulCodePageRange1 to lookup the font encoding RG for supporting modren Unicode encoded CJK fonts? I need to think about it some more. What if Microsoft comes up with Courier New Unicode? I'm more tempted to peek at the font's bounding box to determine if it's charcell. I'll need to check whether this gives good results.

Re: [Fonts]New versions of mkfontscale and FreeType 2 backend
It seems the problem of FT_Get_Char_Index() in checkEncoding().
Hi, I just do the quick testing work with this:

What't the secret in get_index()? X-)
2) After I add those two lines by hand, I still have to edit the fonts.alias
file for running rxvt. The sample for 16 pixel fonts is:
...
The other two GB encoding fonts also need it.
Maybe we need a script to generate it.
3) Besides that, I need to fix the spacing value 'p' to 'c' because the
value 'p' will cause delay in several seconds when start-up rxvt.
...
The other two GB encoding fonts also get the same situation...

Okay, in next version. Thanks.

RG distributions and all *BSD.)
Hmm, there may be problems with this font; I'm told it has bugs.
Maybe the FreeType folks can comment?
RG It seems the problem of FT_Get_Char_Index() in checkEncoding().
RG -if(FT_Get_Char_Index(face, c) == 0) {
RG +if(face face-charmap) {

Very curious. I'll try to understand what's going on.
RG 3) Besides that, I need to fix the spacing value 'p' to 'c' because the
RG value 'p' will cause delay in several seconds when start-up rxvt.
Again, that's a font bug; mkfontscale tries to work out which fonts
are proportional. On the other hand, it doesn't yet implement a
heuristic to distinguich monospaced (-m-) from charcell (-c-) fonts.
I guess a suitable heuristic would be to decalare all monospaced fonts
in East-Asian encodings to be charcell.
RG Would it be merged into next XFree snapshot?
I hope so.
Thanks,

JC With type1 fonts, the UNDERLINE_POSITION is O(PIXEL_SIZE/10). I JC presume the sign is then the problem. Thanks a lot for the debugging -- fix in next version. Juliusz ___ Fonts mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/fonts

(i) to determine whether a font uses glyph names or Unicode indices as its native encoding format (only Type 1 fonts fall into the former category currently); I need this as well to fix MathML mode in Mozilla when using Xft. I believe it would be sufficient (if not exact) to simply check for type1 fonts, with the possible exception of OpenType fonts translated directly from Type1 fonts. I don't know how you'd check for that case though. As for accessing the source-specific fields in the font, I've had the PCF FreeType developer suggest that as the standard way of getting at such information. I'd rather have APIs that returned the private structure from a font (null if the wrong type) so that a magic strcmp wasn't necessary, and so that the library could transcode the information from OpenType (or other wrapper font formats) if available. As long as those datastructures appear in the public API for FreeType, they shouldn't change without a major library version number change.

Re: [Fonts]New versions of mkfontscale and FreeType 2 backend
JC I'm running the new ft2 backend now for all scalled fonts. JC Most everything looks good so far. Great to know. JC Perhaps generalizing -adobe-fontspecific into -*-fontspecific JC would be reasonable? Fine. Although mkfontscale will still only generate `adobe-fontspecific'. JC I'm also having trouble adding /usr/lib/jdk1.3/jre/lib/fonts JC to the font path. Permissions? NFS authorisation? (The server runs as root, not as you.) I'll try to see if I can reproduce it.

Re: [Fonts]New versions of mkfontscale and FreeType 2 backend
JC The average width error is still there for type1 fonts, but AFAICT JC it affects very few programs that one usually doesn't notice. According to David Turner, this may be a bug in FreeType 2.0.9 that was fixed in 2.1.0. I haven't had time to test his guess yet. (Keith, what about importing 2.1.0?)

(The server runs as root, Juliusz not as you.) Not a permissions problem. Everything is on hda. Xft is able to access those files. I have taken another look. The fonts.scale generated by mkfontscale (20020417) assigned the same XLDF to more than one ttf. It also had bad weight values in the XLFDs. (The XftCache in that dir shows that all of the normal weight fonts are weight=100 and the (demi)bold versions are all 200. mkfontscale returns a weight of thin for many but not all of the Lucida fonts therein; it does get a couple of the right.) I don't see that error in the ttmkfdir output, but there is probably something of the sort Both fonts.dir files result in exactly the same error, so there probably *is* some problem with the ttmkfdir version as well. -JimC ___ Fonts mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/fonts
