Re: [Zim-wiki] equation editor

[Paulo van Breugel]

Just FYI, I compiled the latest version of dvisvgm (Ubuntu 14.04 still
packages the ancient 1.2.2). With version 1.14.1, the multiplication sign
(x) is rendered as such. Still, the formula still doesn't look great (see
attached), so the even with the latest dvisvgm version the -n flag is
required.

Re: [Zim-wiki] equation editor

[Paulo van Breugel]

That did the trick.. was just about to compile the latest version of
dvisvgm, but now this works I'll wait till the packages are updated.

It looks great, really happy with this. One suggestion would be to allow
one to set the size (equal to setting the size of an image).

For me the svg option is great, but if you still plan to have the option to
choose between png and svg, it might be a nice idea to have the option to
set the resolution if one selects the png. But again, just suggestions, I
am really happy now :-)

 Hi Jaap and other Zim devs,

 The 'insert equation' function is a great function, producing nice
 looking equations in Zim. However, the resolution of the image (png 
 file)
 that is generated by the addon is fairly low. Is there a way to change 
 the
 resolution of the image? Or even better, would it be possible to add 
 the
 option to store the on-the-fly generaged image as svg instead of png? 
 This
 would provide in perfectly scala

Try "-n -o" instead of "-o -n" ..

Re: [Zim-wiki] equation editor

[Paulo van Breugel]

Hi Jaap,

I had already tried that like below (not sure that is the correct way)

dvipngcmd = ('dvisvgm', '-o', '-n')

But this results in an error "An error occurred while generating the image.
Do you want to save the source text anyway?"

I'll see if I can install/compile the new version

Regards

Paulo

OK there is a work around for this issue: add the "-n" commandline option
for dvisvgm.

Fix for the underlying bug is in newer versions of dvisvgm, but this is not
a pre-requisite when applying "-n".

 Hi Jaap and other Zim devs,

 The 'insert equation' function is a great function, producing nice
 looking equations in Zim. However, the resolution of the image (png file)
 that is generated by the addon is fairly low. Is there a way to change the
 resolution of the image? Or even better, would it be possible to add the
 option to store the on-the-fly generaged image as svg instead of png? This
 would provide in perfectly scalable solution for any document.

 Best regards

 Paulo

Re: [Zim-wiki] equation editor

[Jaap Karssenberg]

Weird, it looks like dvisvgm mixes up unicode characters. Reported the bug
upstream here: https://github.com/mgieseki/dvisvgm/issues/52

Hope they can fix it, would make equations look prettier if we can use svg
instead of png.

Regards,

Jaap

Re: [Zim-wiki] equation editor

[Paulo van Breugel]

Thanks. Unfortunately, the svg file doesn't look correct in my case (see 
attached the tex file, the png file originally created and the svg file 
after patching). I played around with the dvisgm options, but couldn't 
find a solution.


Best wishes,

Paulo

Re: [Zim-wiki] Equation Editor Thought

[Jaap Karssenberg]

Hi Dalon,

Not very difficult to make, but you would need to dig in a bit in the zim
object structure.

Basically you want to modify the equation editor plugin to listen to the
end-of-word signal, and trigger the dialog when you match a latex equation.

The code for this plugin is seperated in zim/plugins/equationeditor.py and
the base class zim/plugins/base/imagegenerators.py

To see an example of how to do the automatic text replacement have a look
at the "insertsymbol" plugin.

Regards,

Jaap

[Zim-wiki] Equation Editor Thought

[Dalon Work]

To the Zim Team,

I've just discovered Zim, and really like what I see. I am a PhD student,
and think this would be a good way to record notes and research. This would
include lots of equations, and am wondering how feasible it would be to
tweak the usage of the equation editor a bit.

My thoughts are to have the equation editor become part of the
auto-formatting, following the same convention of latex for an inline
equation:

Typing $ \int_0^x d\phi $ would then activate the equation editor plugin
and force the picture equation. Right-clicking on the resulting image would
bring up the editing dialogue box as it already does. The idea is only to
change the initial input method. This would prevent lots of trips to the
menu to bring up the equation editor dialogue box.

I'm willing to take a stab at implementing, if I can be pointed in the
right direction, although I am not as familiar with python programming as I
am other languages.

Thanks.

[Zim-wiki] equation editor dialog box

[Ramiro Magno]

Hi

I noticed that the equation editor dialog box is not scrollable. Could
this be implemented in zim's next release? Otherwise long latex input
can make the dialog box too long, actually going over the screen size.
Besides equations, I'm also using the equation editor plugin to make
tables in Zim and I just made a huge table and the dialog box grew
with it :) ...

Thank you.
