I was wondering how to do a routine to convert .GIF and .JPG files
to .PNG files.

Unfortunalety I haven't been able to found information on graphical
formats. Is that confidential information? Or could someone point me
in the right direction?

Thanks.

I suspect you meant..

..because..

Both those pages are still loading, but note this
whould be fairly simple to do, using Java 1.4+.
Marco Schmidt has some examples that might
be closely relevent, one loads an image and saves
to .JPEG, the other saves a screenshot as a .PNG.
