[Fonts]Italic and oblique feature in fontconfig
Hi,
I have a question on font.conf.
In font.conf, we can set up a match target=font for oblique/italic font,
using
the feature from freetype. Hence, when the apps select a italic sans font, by
the
series of match/edit operation, a pre-configured font(s) will used for
different
lang. In my understanding, using the default font.conf file, when a
sans-12:oblique,
the effective font being used is a the preferred font PLUS a scaling with the
matrix
{1,.2,0.1}. When the font, is rendered. It is already scaled. The result will
be a
artificially transformated glyphs image.
But, how can I setting up the font.conf, so that, for every font-family, there
is a list of
entries like :
- AR PL Mingti2L Big5:style=Reguler
- AR PL Mingti2L Big5:style=Italic
As of the current situation, when apps requestion available fonts listing, and
present
the available font to user, obviously, there is no font file which can provide
the italic
Mingti2L font. Hence, the user will only see that, there is one Mingti2L font,
which is
style=Reguler, however, as the artificial scaling/italic is here, I wonder
if there is any
way for me to set up the config, so that, when apps request for fonts,
fontconfig will
also provide AR PL Mingti2L Big5:style=Italic.
Thx
Zenith Lau

Re: [Fonts]Storing the cached font (fonts.cache) information
Hi, I think I've some opinion on this ~ However, storing cached information in what is ostensibly a read-only directory is unfriendly and violates the FSH guidelines. This data is just cached versions of data available from the font files themselves and so the FSH says it should live (somehow) in /var/cache. Good move! Any directories not matching a configured prefix would map to themselves; this makes the existing configuration and cache files compatible. How do you resolve any fonts which doesn't located under /usr/share/fonts ? Some one like to put fonts under different mount points and for me, I put most of my TTF under /usr/X11R6/lib/X11/fonts/local . Is it possible to for this way : 1. Let's assume the caching directory is called FontCachePrefix/ 2. Add one additional mapping table under the FontCachePrefix/ 3. Such that, we lookup the cache for a specific directory by keeping the relation of each cache file and its' corresponding font directory. 4. So that, we don't need a complicated sub-dir. tree under our FontCachePrefix/ 5. The listing can be in binary to minmize the extrax cost for this additional table (file). 6. Finally, for each font directory, we can put the cache as something like path-to.cache or simply 1.cache, 2.cache etc. Does this seem like a good plan? Can anyone come up with a better way of moving the storage of fonts.cache into /var/cache? Yes, personally, I don't like cache placed around my fonts directory : ) Also, this will make reonly /usr partition for practical. But, /var/cache/fonts is already specified in the FHS, that, this directory is for dynamically generated fonts, I quote it here : 5.5.3 /var/cache/fonts : Locally-generated fonts (optional) 5.5.3.1 Purpose The directory /var/cache/fonts should be used to store any dynamically-created fonts. In particular, all of the fonts which are automatically generated by mktexpk must be located in appropriately-named subdirectories of /var/cache/fonts.[footnote 31] 5.5.3.2 Specific Options Other dynamically created fonts may also be placed in this tree, under appropriately-named subdirectories of /var/cache/fonts. Hence, I think, cooperation with FHS is needed or, we simply use another prefix. Though, I think /var/cache/fonts should be the better, as I like the style what fontconfig do. I hope that, the combination ft + fc can be adopted more widely. Zenith Lau ___ Fonts mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/fonts
[Fonts]About Fcpackage and Li18nux2K.
Hi, I have recently read the Li18nux2K. The globalization spec. from li18nux.org. but it seems that, there is no any relation between fontconfig/Xft and this spec. IMHO, Li18nux2K regulate and standardize the direction of i18n while, fontconfig/Xft is complete font management for fonts and the next trend in drawing in X. Why fontconfig/Xft doesn't appear in that spec. ? On the other hand, I remember this is some projects on fonts and type service from Li18nux.org. I afraid there will be two set of facility regard fonts handling in further, if there is no cooperation between fontconfig/Xft and li18nux.

Re: [Fonts]Storing the cached font (fonts.cache) information
Hi, Any directories not matching a configured prefix would map to themselves; this makes the existing configuration and cache files compatible. How do you resolve any fonts which doesn't located under /usr/share/fonts ? The prefix mapping would be configurable; add a map from /usr/X11R6/lib/X11/fonts to /var/cache/fontconfig/x11-fonts and you'll get your cache files for fonts in the standard X directories stored in /var/cache/fontconfig/x11-fonts. 2. Add one additional mapping table under the FontCachePrefix/ I can either store the mapping table in a file or directly in the file system; I don't have a strong preference, but using the file system is likely to involve fewer but more complicated system calls during application startup. It might also involve a slight bit of overhead. The advantage is that there aren't any synchronization issues; each cache file is accessable without reference to a separate file. It seems like that should be more robust in many ways. Sorry, do you mean that, store the mapping table in the file system, you are talking about the first idea? Anyway, I agree that additional table in a file is less robust and involve more overhead. For the configurable prefix mapping, how do it exists? Also it is permissable that, there are many dir in the fonts.conf. Is it possible to store the mapping as properties of the dir elements? But, /var/cache/fonts is already specified in the FHS, that, this directory is for dynamically generated fonts, I quote it here : Sigh. We'll use /var/cache/fontconfig then. I don't really care. Though, I think /var/cache/fonts should be the better, as I like the style what fontconfig do. To some extent, we can ask if a slight reinterpretation of the FSH can be permitted in this case. Ok.

Re: [Fonts]edit antialias=false equivalent in fonts.conf
Hi, There are a lot of knobs to turn in selecting how to render fonts. What I'd like to see is some consistent set of orthogonal knobs all layed out together. Continuing down our current path of a random set of variables seems like a bad plan. Besides AA, embedded bitmap, and subpixel rendering, what is other knobs?? Gamma correction? Scaling? Boldening? or I totally get the wrong direction?? I don't know much, as I'm still a new commer on typography!!

[Fonts]xft with mozilla and openoffice ?
Hello boys and girls, While the GTK and QT works work with Xft, and my desktop is now VV good, at least better than the M$ Win. in my machine. Now I'd like to explore some other things, ie. Mozilla, and Open Office. I've heard that there is a patch for mozilla for xft, but it's a long time ago, seems to be... Does mozilla use Xft currently ?? Which version, or only in CVS ?? Also, how about Open Office, does it use Xft, or in stable release, cvs or not yet started ?? Thx in advance !!

[Fonts]Can I test for the sub-pixel rendering function ?
Hello ! I have read some web and article on sub-pixel rendering, I am using a LCD monitor (I'm a notebook user), and want to try this excellent function. As I am just compile all the thing and install it by myself, I think the default situation is sub-rendering is not enabled. I've add the lines into ~/.fonts.conf, and restart X, but how can I test it ?? Does any modification to fonts.conf will affect the fontconfig behavior immediately?? Or, there is some means / program to make the modification take effects?? Last question, the value for rgba, is [rgb | bgr | vrgb | vbgr], does all this is for sub-pixel rendering ? I know that, rgb or bgr is the seq for the Red, Green, and Blue position, but how about the 'v' stand for?? Thx!

[Fonts]Query about Xft2 and Pango, GDK dependency.
Hi all !! I have download the fcpackage (02-07-17) tarball and I have just upgrade the freetype libs to 2.1.2. I am going to install the fcpackage libs and also gdk, pango stuffs. But I'd like to ask about the dependency problem first. I've read some previous post regarding 'fontconfig, xft2, play together', but I think there is no ans for me, So I post a new one for this!! At this point, I know that, Xft2 is derived from xft1 which font config management function is split into fontconfig libs. and Xft2 doesn't requires xrender; pango and gdk do require Xft1, originally, but should be work fine with Xft2 and friends. OK, do I have some wrong interpretation?? If there is, pls correct me : ). When configuring and compiling fontconfig, I find that, I can't control the configure script to install the pkgconfig file (.pc) to /usr/lib/pkgconfig, while install others under /usr/X11R6 .. and finally I just manually put the fontconfig.pc into where I want. It is a fact or a convention that, we should install the .pc file with same libprefix as other so files within the same package ? Or, I can config it via some means, or anything else ?? While, I'm going to compile the libs, I started from fontconfig, then, Xft (should be v2), yet, I find that, the make install overwrite the original includes dir of Xft1. Is it neccessary to install Xft2 and Xft1 parallelly? Or just override the Xft1 with Xft2 ?? Before I compile and install the Xft2, I've tried to compile the Xft1, but, I don't know how to configure the process, as I can't find the configure script ... what should I do?? It's also the same situation for Xrender libs. Afterall, does all these four libs is necessary? To compile and install it ?? What's the dependency of these libs ? And what's the config file for this ?? /etc/fonts/fonts.config or /etc/X11/XftConfig?? While studying the configure files, and likes inside, it seems that, Xft1 will use fontconfig if there exist. For Xft2, it still require Xrender and also fontconfig. When I run configure in pango, it haven't detect anything about fontconfig. It also doesn't detect the freetype, and Xft header correctly. I am totally stalled on it... any idea to solve it?? checking for freetype-config... /usr/bin/freetype-config checking for FT_New_Face in -lfreetype... yes checking For sufficiently new FreeType (at least 2.0.1)... yes checking freetype/internal/tterrors.h usability... no checking freetype/internal/tterrors.h presence... no checking for freetype/internal/tterrors.h... no checking for FT_Get_First_Char... yes checking for XRenderFindFormat in -lXrender... yes checking for XftFontOpen in -lXft... yes checking X11/Xft/XftFreetype.h usability... no checking X11/Xft/XftFreetype.h presence... no checking for X11/Xft/XftFreetype.h... no Sorry for my long post, filled with Questions !!

Re: [Fonts]Question on xft font library.
Keith, thanks for your patient to answer these!! 1. It seems that XFT is so good, so what's about the conventional fonts module inside X, like the xtt, freetype, type1, etc... The X server can still provide fonts for applications not yet ported to Xft. These modules will be useful as long as you have some older applications left around. Do you mean that, these two module is stable enough, and no active development works is carried on these? 3. If I want to use XFT, should I use DRI modules?? The older Xft did require the Render extension, but all XFree86-based X servers have provided that for over a year now, including those built from sources directly from the DRI project. The new Xft (not yet released, but in CVS) doesn't even need Render and will work on any X server. I have heard something about Xft2, I even get a copy of it from somewhere, I forget, but it is binary. I remember that, I can't find the source from that site. Anyway, what's the version of Xft which is considered latest, and what's the version included in XFree86-4.2? I also heard about fontconfig, by the paper on you web site, but is it include in XFree4.2? Again, what's the current version. May I have some more references relating to fontconfig? Though, I know that these two libraries (Xft, and fontconfig) is develop and maintain by Keith, but does it have a official website, or these two library won't have a website due to the fact that, it is under XFree?? 6. In xtt, the ttcap functions is useful for chinese fonts (I am a Chinese), however, does freetype provide this, or xft provide this?? 7. If similar functions of ttcap is not available in xft and freetype currently, will it been in the todo list later. ttcap isn't relevant for Xft. Xft provides full support for all TrueType and Type1 fonts, and has some special support for Han languages to ensure that the right fonts are used in each locale. Xft supports a large number of rendering configuration options for fonts. The subsetting options aren't relevant as Xft always incrementally rasterizes fonts. Does incrementally rasterizes fonts means, the cache mechanism for inside Xft, ie. Xft will only rasterizes glyphs on demand, right? but I don't understand, why those subsetting options aren't releveant for Xft. IMHO, I just think that, to handle such functionality, I can add these function within freetype, or do something else on top of it. For the fontconfig, and Xft, as these two is responsible for the query fonts, and get glyphs, and render it on X. It should handle the case that, alias a font with regular face to italic or bold, also, get the desired glyphs (transformed) for the client application. Does my logic right, or stupid ?? I want to this answer as this direction is right, as Gnome and Kde is shifting to use Xft, enable the function (bold/italic transformation) would benefit more than any other possible solution.
