Latex formula editor ?
Stef Mientki
is there a formula editor availabale for wxPython,
that converts Latex formula to png files.
(so they can be embedded in html)
thanks,
Stef Mientki

I would be gob-smacked if you could find anything pre-built for this.
It's not a simple task. If you know TeX and LaTeX are installed, you
can certainly write your own scripts to do the conversion, but the
TeX/LaTex installation on my hard disk is about 650MB.
OpenOffice has an equation writer that might be usable in other
contexts. That's worth checking.

You can use Python to script OpenOffice, so that might be doable.

Oooh, that's a great hint -- I wish I had remembered that first. Here's
a link to a sample:

Actually, I don't know if it will help the original poster; he said that he wanted an editor, and certainly matplotlib cannot help with that. I should have read more closely :/ --thank you all for your comment,

a quick and dirty summary
- Latex itself is much to heavy
- Openoffice component could be a good candidate, but I know nothing of OO, so getting out some small component seems a lot of hassle
- MatPlotLib could work, but requires a working Latex ( so too heavy)
- Mimetex.exe seems to be a very good candidate, small and fast. I'm not sure this will work on other than Windows
With mimetex and 30 lines of code, I made a first version of a real-time formula editor dialog.

yup -- I saw some folks working on a project to make a TeX designed for
embedding a couple years ago -- it might be worth googling for.

Ah, I think you missed a feature. MPL can optionally use a full TeX
distribution as the engine, but it also has a built-in TeX
implementation with a limited feature set for equations (i.e. no
paragraph layout, etc). Depending on your needs, it may be OK -- and
it's pure Python.

Why not -- it looks like it's ANSI C, GPL;s and there are binaries for a
bunch of OSs. It would be kind of cool to wrap it as a python extension,
rather than the CGI interface.

OK -- I couldn't help myself, here is a quick and dirty TeX editor,
written using Matplotlib.
Enjoy!

This is SWEET. It is, however, unfair of you not to share.
Did you find mimetex.exe as a download, or did you have to compile it?

works smoother than the mimetex version (and pure Python)
Indeed I missed that MPL contained a subset of Latex.
So I think I'm going for your solution,
One other thing, does anyone know a good set with math icons.
The best I could find is

WelI I want to make a number of groups with different sets of math symbols,If you are using the MPL solution why not generate them on the fly or as a part of the build process � then you will be able to a) Generate the size(s) you need and b) be sure that they are all supported by MDL.
that will act as a toolbar to insert the corresponding latex info.
So it will cost a lot of work to generate and include them all,
and probably I'll miss a few.

Stef

The MPL version, has a number of problems:
- it misses a number of commands, like \small , \tiny
- the image size is fixed (to the original window size ?) with a lot of white space around the formula
(therefor the image size is also much larger than necessary)

I'm glad it's helpful.
You might want to take a look at:
matplotlib.mathtext.MathtextBackendBitmap()
A backend to generate standalone mathtext images. No additional
matplotlib backend is required.
That may let you eliminate the MPL figure stuff (though it's not too
much coding overhead)
One thing I didn't figure out last night was how to tell how large a
given chunk of rendered text is, so that you can do things like center
it on the Figure. Some poking into the docs and code may help figure
that out, or a question to the MPL list.

Perhaps you could generate them with MathtextBackendBitmap().

well, it's certainly incomplete -- I don't know how hard it would be to
add things like that. Those particular commands could be pretty
straightforward.
If you want EVERYTHING, a full LaTeX distribution is your only option.
Though maybe mimeTeX has significantly more than MPL.

See my previous note -- I suspect you can solve that one.

tested the "Cambria Math" font on wxPython 2.9.1 on
Windows 7, all the random code points in the "Mathematical
Operators Unicode code block" I randomly selected are
rendered in a StaticText, a TextCtrl or in a STC.
I have other math fonts I'm using in XeTeX. I did
not test them, they are not installed at the system
level.
