Qt Other Utility

Score 71%



Homepage:  Link
Depends on  Qt 4.x
Downloads:  1317
Submitted:  May 3 2009
Updated:  Jan 1 2012


This project is continued from kde-apps.org. Since it was re-written for pure Qt4, its place is here I guess. On kde-apps.org, the project reached 3694 downloads before being transferred to qt-apps.org.

KLatexFormula is an easy-to-use graphical user interface
for generating images (that you can drag and drop, copy and paste or save to disk) from LaTeX equations.

Comprehensive download and install instructions can be found here: http://klatexformula.sourceforge.net/klfwiki/index.php/User_Manual:Downloading_&_Installing

The program has two modes, shrinked and expanded mode. Shrinked mode is straightforward, and expanded mode lets you to specify a few options.

You can use KLatexFormula in command-line mode (eg. for scripts)by invoking klatexformula_cmdl executable. Type klatexformula_cmdl --help for more information. A C++/Qt library is also provided.

Manuals are centralized on a wiki at http://klatexformula.sf.net/klfwiki.

Binaries are also available for Mac OS X and Windows.

Note that the K in the name "KLatexFormula" is there for historical reasons; this program is now a pure Qt 4 application.

I hope this can be useful for someone. I'm not sure of having much time to spend for keeping this application up to date, but I was encouraged to publish it so here it is... :-)

Sorry, I should have specified this more clearly !

klatexformula-3.0.1> qmake
klatexformula-3.0.1> make

and to install in /usr, run as superuser:

klatexformula-3.0.1> make install

For these steps to work, you need the Qt4's qmake to be in your $PATH.

Best Regards,
Philippe Faist

Thanks for the porting to qt4. It is a very very useful app, and now it is faster, looking better, better integrated.

 command-line mode

Is command-line mode was removed in 3.1.0 version?
symlink klatexformula_cmdl works like klatexformula.

Hi nucleas,
klatexformula_cmdl is symlinked to klatexformula because now klatexformula itself suppports command-line instructions. type klatexformula --help for basic help. Basically, you can run either the full GUI, either in batch mode, each time possibly specifying latex input and possibly output file, etc.
Batch mode is automatically activated if a --latexinput or --input option is given.

Hi, thanks a lot for this wonderful application, I use it for 3 weeks now, with OOo impress and the result is near perfection ;)

I would like to know if there is a possibility to add an anti-aliasing option, because I observed that long mathematical expressions are better viewed if I apply the corresponding blur effect after png export with the Gimp.

Thank you very much.

Hi Olivier,
Thanks for your feedback.
Currently already the option -d{Graphics,Text}AlphaBits=4 is passed to gs (maximum antialiasing). However I don't see how I can improve antialiasing through gs (which would be in my opinion the best solution). A possible feature would be to run gs with a multiple of the given dpi resolution, then scaling down the image to the required resolution using a smooth scaling algorithm. Is this what you're suggesting?

Hi Philippe, thanks for your answer.
I don't know a lot about gs, but the proposed solution with a smooth scaling seems interesting.
If needed, I can be beta-tester :D
best regards,

With 3.2.0 I released a very simple blur plugin provided at https://sourceforge.net/projects/klatexformula/files/klatexformula-plugins/klfplugins-2.0/.

But consider using OpenOffice draw format export, it integrates more natively into your documents; you can also use the new KLatexFormula OpenOffice integration toolbar (see http://klatexformula.sourceforge.net/klfwiki/index.php/User_Manual:Tips_and_Tricks)

Hi Philippe,

I am pleased to use the new version since this morning, and it works perfectly.
I choose the possibility to export to OOo draw format and the result is really perfect for what I need (and do not).
I will test the plugins you provide asap !

Thanks again for this wonderful software ;)

Best regards
