The TCExam LaTeX render converts the code to a PNG image that is cached on CACHE folder for successive calls to the same code.
The LaTeX rendering requires the following additional software:
- Windows I suggest to use MiKTeX (http://miktex.org/);
- ImageMagick (http://www.imagemagick.org/);
- Ghostscript (http://sourceforge.net/projects/ghostscript/).
Then you have to edit the file /shared/config/tce_latex.php to match your system settings. ( main settings shown below)
/**
* Path to LATEX (/usr/bin/latex).
*/
define (‘K_LATEX_PATH_LATEX’, ‘C:/Progra~1/MiKTeX~1.9/miktex/bin/latex.exe’);
/**
* Path to DVIPS (/usr/bin/dvips).
*/
define (‘K_LATEX_PATH_DVIPS’, ‘C:/Progra~1/MiKTeX~1.9/miktex/bin/dvips.exe’);
/**
* Path to ImageMagick convert (/usr/bin/convert).
*/
define (‘K_LATEX_PATH_CONVERT’, ‘C:/Progra~1/imagem~1.4-q/convert.exe’);
/**
* Path to ImageMagick identify (/usr/bin/identify).
*/
define (‘K_LATEX_PATH_IDENTIFY’, ‘C:/Progra~1/imagem~1.4-q/identify.exe’);
