 Please, answer me soon! Help me! 
 Thank you!

If you mean you want a block of LaTeX formatted text in a drawing, then the
advice about using Sketch may be helpful to you.

However, it sounds to me like you want to render some math and then use it as 
an artistic element.

To do that, what you'll want is to work from Postscript.  Render the desired 
LaTeX to Postscript.  Then use Gimp or ImageMagick or Ghostscript (which is
what they all use under the hood, actually -- and from the gs command line
you can be much more specific) to render the Postscript to a bitmap at the
desired resolution (pixel-size). Voila! You have a bitmap of the desired 
object, which you can then manipulate in Gimp -- color it, mask it, run
filters on it, whatever.

Variations are possible, of course -- in some programs you can rotate the 
postscript before rendering it (if that's required).  Otherwise you can just 
do a bitmap rotation -- in practice that usually works well enough.

I used a very similar method to render Japanese Kanji -- I used Yudit with 
the Cyberbit far-east fonts and rendered the result as Postscript. The rest 
is just like the above.  Basically, if you can get Postscript, you're most of 
the way there.

Cheers,
Terry

[Gimp-user] Knitting Images?

[Terry Hancock]

A long, long time ago, in a graphics package far, far away ...

There was a utility, which I think was called knit which would correlate 
two images, look for an overlap region and use the result to composite them 
into a single image. The application, of course, was putting together 
multiple scans or photos of the same original when the scanner or FOV was too 
small to capture the whole.

Does Gimp have any equivalent to that and/or is there an external program 
that I can use (on Linux) to do it?  Also, is there a more appropriate term 
for it, because gimp knit images does not turn up anything too appropriate 
on Google. :-)

Thanks for any pointers,
Terry
