ZIM Equation Plugin Windows Error Message

[Simon Theis]

Hi,

I am running Zim release 0.60 on a Windows 7 - 64 bit host. I'd like to use the plugin 'Insert Equation'. To do so, I have installed the basic Miktex package release 2.9.4813. I can activate the plugin in the plugins list, since the dependencies are fulfilled (latex and dvipng are installed). Now when I want to insert an equation the following happens:

a) I click on 'Preview': An empty graph with a red cross is created
b) I click on 'OK': An error message pops up: 'An error occurred while generating the image. Do you want to save the source text anyway?'

I have tried different Zim releases without success. Do you have any ideas? Maybe I have to modify the Windows path variables (https://answers.launchpad.net/zim/+question/99561)? If so, what do I have exactly to do?

Thanks for your help,
Simon

I don't think the path variable is the problem -- if the plugin can be
enabled, it found the applications.

When you generate a preview, can you open the latex log in the dialog to
see if there is any error there?

If not check %TMP%/zim.log to see if there is an error output there.

Regards,

Jaap

Thanks for your immediate reply. I cannot find a Miktex log file. Here is the output of the %TMP%/zim.log:

Obviously, there is a problem with the dvipng.

[Jaap Karssenberg (jaap.karssenberg)]

Might be that not all of the options used are supported in your version?

Try calling dvipng from a dos commandline with the given options and see
what happens.

Jaap

Solved.

I executed

dvipng "-q" "-bg" "Transparent" "-T" "tight" "-o" "c:\users\simon\appdata\local\temp\zim-Simon\equation.png" "c:\users\simon\appdata\local\temp\zim-Simon\equation.dvi"

in the command line. Then a window popped up, telling me that some font was not installed. I was also asked, whether I wanted to install the missing font. So I installed the it and now everything works fine; i.e. I can use equations.

Thanks for your help and thanks for the great tool,
Simon

Simon and Jaap,

Would you mind telling me which fonts you ended up installing? I just encountered the same error and ran the same set of commands on my equation, but did not get the pop-up window offering to install the fonts.

Thanks,

Derek

[Jaap Karssenberg (jaap.karssenberg)]

@Derek Did the command run and succeed to generate the png image, or did it
also give an error.

Dear Derek,

I cannot remember what fonts I had to install.

The reason why the window popped up is because of the tool Miktex (http://www.miktex.org). So I suggest you install Miktex and then you run the command as described in my previous post again. Of course you have to adapt the paths for

"c:\users\simon\appdata\local\temp\zim-Simon\equation.png"

and

"c:\users\simon\appdata\local\temp\zim-Simon\equation.dvi"

Good luck,
Simon

Derek, Simon:

I had the same problem with Simon on a Windows 8 64bit machine with a freshly installed MikTeX 2.9.
I walked through the same process (manually running the dvipng command in the command line and let MikTeX install the missing package). Now the equations can be generated properly.

The missing thing pointed out by MikTeX was:

fonts\map\tt2pf\ttfonts.map

which is a part of the zhmetrics package.

Hope this helps.

Cheers,

Shih-Yuan

Hi!

I had the same problem and the solution was installing the missing font, as reported above. May I suggest to include a comment in the Zim web page in "Equation Editor plugin" so that people is aware that they have to manually install this font before using the plugin?

Great tool!
