• Converts TeX to an image. May be used to embed formulas in PhpWiki.

    Usage

    <<TexToPng arguments>>

    Arguments

    Argument

    Description

    Default value

    tex

    TeX Commands (default: text mode), use $...$ for inline math formula style and $$...$$ for large formula style

    magstep

    magnify image by (1.2 to the magstep)

    img

    Image type (png, jpeg or gif), if chosen image type is not available use the first possible from png, gif, jpeg (in that order)

    png

    subslash

    on or off: substitute slashes by backslashes (to avoid the backslash bug of the database pear interface)

    off

    antialias

    on or off: render ps to img with antialias option. This produces higher quality output but is slower and needs more disk space.

    transparent

    on or off: produce transparent background instead of white background. Seems to be buggy (in pstoimg - not my fault)

    center

    on or off

    off

    Examples

    This produces a little help screen:

    <<TexToPng>>

    A simple formula:

    <<TexToPng tex="$x^2$" >>
    $x^2$

    A more complex formula:

    <<TexToPng tex="$$/int^/infty_{-/infty} dx {1 /over /sqrt {x^2+1}}$$" subslash="on" >>
    $$/int^/infty_{-/infty} dx {1 /over /sqrt {x^2+1}}$$
