Faulty vertical spacing
Closed this issue · 9 comments
Hi,
Combining Latex It! with Ubuntu 20.04 and Thunderbird 68.10.0 I get a weird vertical spacing. I'm attaching a screenshot of how the rendering goes (for an expression between dollar-signs). The vspace seems to be in the (html?) embedding, not in the png, which has the right dimensions. I can get around the issue by manually downgrading to version 0.6.8, and disabling updates. For this version I also have to change the ImageMagick policy lines.
Thanks in advance! And ofcourse thank you so much for a great addon.
Best,
Simon
Thanks for filing this issue.
A little background: The new version 0.7.x aligns the generated picture with the surrounding text (see #36) and I guess that's where it goes wrong. It uses the --depth option of dvipng (https://tug.org/texinfohtml/dvipng.html#index-depth-reporting).
To help tracking down the problem, it would be helpful to see the debug output of LatexIt. You can enable it in the add-ons settings page (☰ > Add-ons > Latex It!). Please tock both Generate a log report and Generate debug info and rerun LatexIt. This should show some info directly in the mail message you are editing. (Get rid of it by clicking on the x in the top right corner of the box containing the log.)
Maybe you can show a screenshot of the settings dialog as well?
Thanks for the quick reply! Directly in the mail message there wasn't much extra info (note that the second time I compile
The debugger window does show some errors:
Finally, here are the settings (I commented out the additional packages that I use):
For your information, here's what the terminal says after using Latex It:
Indeed, that run report does not report much at all …
In your Template can you please replace the line
\usepackage[utf8x]{inputenc}with the two following lines:
\usepackage[utf8]{inputenc}
\usepackage[active,displaymath,textmath]{preview}and try to re-run it.
I cannot spot any message related to LatexIt in Thunderbird's debugger window.
Amazing, that seems to solve it!
Well, it's not that amazing, since dvipng --depth requires the preview package. BTW you should now see your formulae nicely aligned with the surrounding text.
The template is automatically updated, if the user has not changed it (#58 (comment)).
Changing utf8x to utf8 is just reducing some dependencies on the Debian system (see #8), so had not a direct impact on your problem.
@protz: I guess, we might get more of this. Is it possible to issue a warning when updating the add-on?
The reason, why the second run in #63 (comment) "worked" is a result of bug #64.
The version 0.7.3 hit the Thunderbird add-on repository, so this can be closed.
