Re: Rotating X Fonts?
1. Is there a way to know at run-time whether or not an X-server will actually be able to honor the rotated font request? Not officially. However, you may have a look at the font property ``RASTERIZER_NAME''. If it says ``FreeType'', ``X Consortium Type 1 Rasterizer'' or ``X Consortium Speedo Rasterizer'', it will probably work. If it's something else, all bets are off. 2. Is there any documentation/standard for the use of rotated fonts, e.g., the name of the rotated font above is mostly a mystery between the []? The XLFD spec, version 1.5, Section 4. http://www.x.org/docs/XLFD/xlfd.pdf 3. I suspect the issue might be a discrepancy between the installed fonts on the two X servers. No, it's more probably a discrepancy between the font backends being used. I suspect that Hummingbird uses a rasteriser called the ``X Consortium Bit Scaler'', which has been disabled in X.Org. Core X11 fonts are deprecated in X.Org. I strongly recommend that you switch to Xft, which doesn't have any of these issues.

Rotating X Fonts?
Hi, I am struggling with an application, written by another, that attempts to rotate fonts for use on the Y label of a plot. It uses the following font names: -adobe-helvetica-medium-r-normal--18-180-75-75-p-98-iso8859-1 (the non-rotated version) -adobe-helvetica-medium-r-normal--0-[+0.0+18.0~18.0+0.0]-75-75-p-0- iso8859-1 (the rotated 90 degree version) In my environment this rotation is not uniformly successful. It works on MS Windows machines running Hummingbird Exceed, but fails for Linux machines using Xorg.Failure here means the font is displayed just not rotated. Xorg is able to rotate a font named utopia, so this is somewhat specific to the font involved. So I have a few questions whose answer would help me progress please: 1. Is there a way to know at run-time whether or not an X-server will actually be able to honor the rotated font request? 2. Is there any documentation/standard for the use of rotated fonts, e.g., the name of the rotated font above is mostly a mystery between the []? 3. I suspect the issue might be a discrepancy between the installed fonts on the two X servers. Suggestions for how to diagnose and fix any such discrepancy? Thanks for your time.

They were specified in X11R6, but never really used much since they specified rotating each individual character, but not the line of text, so weren't very useful. (i.e, asking it to rotate would result in ^ V being drawn and not the more commonly expected ^ V .) The specification of what you can put between the [] is in the XLFD (X Logical Font Description) specs, along with the details of each of the 13 other fields between the dashes. A PDF version is posted at http://www.xfree86.org/current/xlfd.pdf - the section you are looking for is Matrix Transformations, starting on the page numbered 24 (page 26 of the PDF). -- -Alan Coopersmith- [EMAIL PROTECTED] Sun Microsystems, Inc. - X Window System Engineering ___ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg
