Bugzilla – Bug 132047
Mozilla MathML displays incorrectly
Last modified: 2007-02-16 14:17:14 UTC
I'm having problems with Mozilla viewing MathML. The problem I am having with the build from SuSE 10 is different from what happens with the mozilla 1.7.12 from mozilla.org. If someone would verify this, I would appreciate it. I want to report one, or perhaps two bugs. With the Mozilla that ships with SuSE 10, I do not see the ∄ in the xhtml below. With the build from mozilla.org, there are incorrect and, downright weird fonts shown. If you get an error saying you need to install special fonts, you can ignore that in this case. If you want the fonts, follow the links in the error message, and get the _4.1_ fonts. One thing I've noticed with the Mozilla from SuSE is that it seems to have MathML fonts built in. I don't get the error telling me to get the Math fonts that I get from the mozilla.org build. Builds of Firefox don't show the ∄ but they do show most fonts correctly. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1 plus MathML 2.0//EN" "HTMLFiles/xhtml-math11-f.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title> fundamentals-of-mathematics.xml </title> </head> <body> <mml:math xmlns:mml='http://www.w3.org/1998/Math/MathML' xmlns='http://www.w3.org/1998/Math/MathML' id='peano-3'> <mml:mrow> <mml:mrow> <mml:mo>∄</mml:mo> <mml:mo>(</mml:mo> <mml:mrow> <mml:mi>α</mml:mi> <mml:mo>∈</mml:mo> <mml:mi mathvariant='double-struck'>N</mml:mi> </mml:mrow> <mml:mo>)</mml:mo> </mml:mrow> <mml:mo>∋</mml:mo> <mml:mrow> <mml:msup> <mml:mi>α</mml:mi> <mml:mo>′</mml:mo> </mml:msup> <mml:mo>=</mml:mo> <mml:mn>0</mml:mn> </mml:mrow> </mml:mrow> </mml:math> </body> </html>
Created attachment 56338 [details] Looks good here
The screenshot shows that everything looks fine here. Please verify that or point out what's wrong. The not-exist symbol is shown, the special fonts aren't installed.
Created attachment 56426 [details] Seamonkey 2005110105 nightly build This is the second part of what I was describing. I deleted these: /usr/X11R6/lib/X11/fonts /etc/X11/xorg.conf /etc/fonts And reinstalled all fonts and xorg rpms. The SuSE-built Mozilla now functions as expected. I do not receive the missing fonts error with the SuSE-built Mozilla, but I do get it with the mozilla.org build. The only way I know of to get that error to go away is to put the fonts under the /usr/X11R6/lib/X11/fonts, for example, /usr/X11R6/lib/X11/fonts/wri/4.1/Type1 /usr/X11R6/lib/X11/fonts/wri/4.1/truetype (wri = Wolfram Research Inc.), edit the /etc/X11/xorg.conf and add the paths to the FontPath. That, I believe, invalidates the /etc/X11/xorg.conf.md5. SUSE LINUX Documentation Chapter 35. The X Window System / 35.3. Installing and Configuring Fonts, seems to be telling me to put these fonts in the respective /usr/X11R6/lib/X11/fonts/Type1 /usr/X11R6/lib/X11/fonts/truetype directories. For obvious reasons this is not a good solution. For my immediate purposes I only need the fonts to work for one user account, and would prefer to install them in the user's directory space. In previous versions of SuSE Linux, that has met with varying degrees of success. I shall attempt this again, and post an update. I'm trying to determine if the problem with the mozilla.org builds is SuSE specific, and whether I need to file a bug report with mozilla.org. I would also like to provide as much information as I can in such a bug report.
Whoops! I meant to include this: http://www.w3.org/Math/testsuite/testsuite/Presentation/TokenElements/mo/mo6.xml
Comment on attachment 56426 [details] Seamonkey 2005110105 nightly build I am quite convinced the problem demonstrated by the screen capture is not related to the missing font error. Nonetheless, I did promise an update on my effort to install the wri fonts. Neither putting the fonts in ~/.fonts/wri/4.1/{Type1,truetype}, nor in corresponding /usr/share/fonts subdirectories solved the problem of X not loading the fonts. In the ~/.fonts.conf I put: <?xml version="1.0"?> <!DOCTYPE fontconfig SYSTEM "fonts.dtd"> <fontconfig> <dir>~/.fonts/wri/4.1/truetype</dir> <dir>~/.fonts/wri/4.1/Type1</dir> </fontconfig>
That testcase displays fine for me out-of-the-box in SUSE 10.2. So does http://www.w3.org/Math/testsuite/testsuite/Presentation/TokenElements/mo/mo6.xml. So what is the problem here? I'm confused.
No reaction on this bug for a long time. Closing as CANTFIX.
