Certainly, if that is all that is required.
I'm not sure about the commercial software, but my very own MGIF will deal with 24 bit colour even if you are running on an ST with a monochrome monitor (where it can use flickering to simulate four greyscales). It currently supports all normal Atari graphics modes, up to and including Falcon TC, as well as graphics cards with chunky 8 bit mode (but unfortunately not yet any other 16 or 24/32 bit modes).
MGIF has lots of image processing functions (_very_ fast DSP accelerated convolution and median filtering among them), including filtered scaling, and supports GIF, JPEG, TGA and a couple of other image formats, so it might well do the job in this case.
Apart from a few things like text rendering, MGIF currently does not support creation of anything new in an image. It does cover a lot of aspects of image processing, however.
A neat aspect (IMHO ;-) is that it can be used as a TOS mode program or in batch mode as well as using the GUI.
Anyway, since it's free (GPL), there's little harm in trying it out. It's been quite a few years since I last did anything with it (I got irritated when trying to talk to Unisys about the lzw (GIF) patent...), but I fully intend to pick it up again some day (the lzw patent expires next year, IIRC). Any comments, suggestions, bug reports, etc are very welcome.
