[sage-support] Re: jsmath fonts bafflement
OK, thanks for the detailed description of what is happening. Now
this makes me think that this IS a jsMath bug, and not an improper
image font installation. If the image fonts are working in Firefox,
then they are installed properly.
The error you are getting about jsMath thinking that you are trying to
load jsMath from a different server is the key, here. It is not able
to load ANY of its extra files (including things like the control
panel, and IS-specific customization files) because jsMath is confused
about where it was loaded from. What I suspect is the problem is that
the port number is confusing jsMath in IE. Every browser except IE
normalizes URL's so that they include the protocol, host, port
number, etc, so when jsMath looks to see where it was loaded from so
that it can load additional files, that information is all right
there. But in IE, the URL is left as it is originally in the HTML
file, so jsMath must reconstruct it itself. It looks like it is
leaving out the port number, and so jsMath is looking for its
components in the wrong place, and so not finding them.
As an experiment, if you could insert the lines
script
jsMath.Autoload = {root: https://99.240.209.8:8000/}
/script
to the font test HTML file just before the script tag where jsMath.js
is loaded, and then see if that makes it work in IE7, that would tell
us if this is really the problem.
In the meanwhile, I will work on that part of the jsMath code and get
it to include the port number.

OK, thanks for the clarification. I had misunderstood. In Firefox,
can you click on the jsMath button in the lower right and tell me
what font mode is reported next to the jsMath version number?
For some reason, the fall back to image fonts is not working for me,
using my sage server on OS X, and viewing the worksheet on a PC
running IE7. I don't know if there is a problem with the image font
installation in sage, a jsMath problem, or an IE problem. But, as
long as Firefox will work, I am happy, and feel no need to spend
more
time on this issue. But, if you think there could be a jsMath bug
that you want to investigate, I would be happy to help out.
I suspect it is probably an installation problem with the image
fonts. In any case, I'm happy not to spend any more time on it
myself.
If an installation problem is the conclusion, then I'd like to spend
at
least a bit more of my time on it, as it would clearly be a Sage
problem
then. It seems funny to me that it would work in one browser, but not
another.
I think Davide's suggestion above (look at the font mode and jsmath
version number for both IE and Firefox) might help pinpoint the
problem.
Do you see the same problem with sagenb.org? That server has the
image
fonts installed as well.
When I attempt to load a worksheet from my server with IE7, I get a
dialog In order for jsMath to be able to load the additional
components that it may need, the jsMath.js file must be loaded from a
server in the same domain as the page that contains it. Because that
is not the case for this page, the mathematics displayed here may not
appear correctly. When I view worksheets in IE, I see raw latex
where I should see rendered latex.
In IE, nothing happens when I click on the jsMath button at the bottom
right - i.e. I cannot open the jsMath control panel. Also note that
the jsMath button is only seen when I scroll all the way to the end of
the worksheet, unlike with other browsers where it is always visible
at the bottom right of the screen. I assume IE is not properly
rendering this element.
In Firefox, no jsMath font dialogs appear, and the latex code is
rendered. The font mode is shown as Image symbol fonts, and the
jsMath version is 3.6a.
At sabenb.org, I get no jsMath font warnings in IE. Initially, I see
raw latex, but eventually it is replaced with properly rendered
latex. The control panel shows the font mode as Image symbol fonts.
I viewed my server again in IE, and had the same problems that I
reported above.
I conclude that I have a problem with the image font installation on
my server. But I have no idea how to troubleshoot it.
For info, my public worksheets are athttps://99.240.209.8:8000/pub/

I need some help deciphering how to do this. I am very new to sage,
and have not yet dug too deep into the underpinnings. I can't find an
html file for my font test worksheet. Looking at the text file that
appears to define the worksheet, I don't see any script tags. I tried
adding those script lines directly before the first cell, and in the
first cell that appears to call for jsMath fonts, and at the very
start of the file, but neither change made any difference in IE. But,
if I look at the Font test page html source in my browser, I see that
even if I add your script at the very start of the worksheet file, the
script is loaded well _after_ jsMath.js is loaded.
I clearly have not accomplished your request. Maybe I need to test a
temporary modification to jsMath.js, but I do not know javascript, so
I don't know what changes to make. Or maybe I need to temporarily
modify whatever code creates the html headers for worksheets, but I
have not yet found where that code is.

OK, from the testing that I've done, it looks like this is, indeed, the problem, and you won't have to do the testing that I suggested. It turns out that this problem was fixed in version 3.6b of jsMath, and you are running 3.6a, so if you download the latest version of jsMath and replace the copy at javascript_local/jsmath on your site, it should take care of the problem. When you unpack the new jsMath, move the fonts folder from the old one to the new one before replacing the old copy, or you will loss the image fonts that you have installed. You can get the new jsMath from http://sourceforge.net/project/showfiles.php?group_id=172663 Hope that clears up your problem.

[sage-support] Re: jsmath fonts bafflement
I do not think it is a jsMath bug. If I understand you, by works correctly you mean that Firefox doesn't show the font warning message (while IE7 does, which you consider not working correctly). You have tried several means of installing the jsMath image fonts as a solution to this problem. The jsMath font warning message actually has nothing to do with whether the image fonts are installed or not. It has to do with whether the user who is reading your page has the jsMath TTF fonts installed on their computer or not. If they don't, the message will appear and jsMath will fall back on the image fonts. (If you don't have the image fonts installed, then jsMath would report the infamous -7 error during startup). It turns out that jsMath used to use a different set of TTF fonts that where created by BaKoMa for use with TeX installations, but they ended up being problematic, so I made jsMath-specific TTF fonts to get around those problems. Under some circumstances, however, jsMath can still make use of the older BaKoMa fonts, and so if these are available, it will use them rather than the image fonts. That is probably what is happening for your Firefox, as the BaKoMa fonts are used by Firefox as part of its MathML implementation, so you probably have them for that, whereas your IE7 users don't have them installed. (I'm not sure what fonts the MathPlayer plugin for MathML in IE requires.) In any case, the way to eliminate the font warning message is to install the necessary fonts on the users machine (not install image fonts on the server, which you should do anyway). If you really want to remove the font warning message even when the user doesn't have the fonts, you can change the showFontWarnings setting to 0 in the jsMath/easy/load.js file that you are using. The font warning message is there so that your users can tell that they would have a better experience of your page if they installed the fonts. It is actually an indication of jsMath working CORRECTLY, not an error. When the message is issued, jsMath should continue to work, but will use the image fonts rather than native fonts, which produces somewhat poorer quality rendering, doesn't rescale if you change the font sizes, and doesn't print well. If you remove the warning, the users will never know that they could have better rendering and better printing.

If I understand you, by works correctly you mean that Firefox doesn't show the font warning message (while IE7 does, which you consider not working correctly). You have tried several means of installing the jsMath image fonts as a solution to this problem. By works correctly, I mean that Firefox displays the nicely rendered equations, while IE only displays raw latex code. The jsMath font warning message actually has nothing to do with whether the image fonts are installed or not. It has to do with whether the user who is reading your page has the jsMath TTF fonts installed on their computer or not. If they don't, the message will appear and jsMath will fall back on the image fonts. (If you don't have the image fonts installed, then jsMath would report the infamous -7 error during startup). For some reason, the fall back to image fonts is not working for me, using my sage server on OS X, and viewing the worksheet on a PC running IE7. I don't know if there is a problem with the image font installation in sage, a jsMath problem, or an IE problem. But, as long as Firefox will work, I am happy, and feel no need to spend more time on this issue. But, if you think there could be a jsMath bug that you want to investigate, I would be happy to help out. It turns out that jsMath used to use a different set of TTF fonts that where created by BaKoMa for use with TeX installations, but they ended up being problematic, so I made jsMath-specific TTF fonts to get around those problems. Under some circumstances, however, jsMath can still make use of the older BaKoMa fonts, and so if these are available, it will use them rather than the image fonts. That is probably what is happening for your Firefox, as the BaKoMa fonts are used by Firefox as part of its MathML implementation, so you probably have them for that, whereas your IE7 users don't have them installed. (I'm not sure what fonts the MathPlayer plugin for MathML in IE requires.) Thanks for the explanation.

I tried sage -f jsmath-3.6a.p0 - that at least claimed to install the

I then tried, inside sage: install_package('jsmath-image-

I restarted sage, and rebooted the work PC, but I still got the jsmath

What else should I try? Other than this small issue, sage is
wonderful.
Try (from the command line):
sage -f jsmath-image-fonts-1.3p1
and (if that doesn't fix the problem), post the output to the above
command in a message here. There may be a problem with you getting the
jsmath-image-fonts spkg.
Thanks,

I have made some progress in that I discovered that Firefox 3 works
