Just looked at the description of calligra-krita: "Krita is a creative sketching and painting application." I have never been able to do any kind of sketch or hand-drawn anything on the computer, and I really
don't want to anyway. All I need to do is clean up some photographs a little--crop, increase contrast or density, that sort of thing. (I do use AutoCAD, but that's not sketching or painting!) Thanks anyway. --doug
Just because Krita (or Gimp, or tuxpaint, even
allow "drawing" and "painting" doesn't mean they are limited to this, or that you have
to use them exclusively for this. They are very
good for interactive manipulation (cropping, skewing, gamma adjustment, levels/curves adjustment, etc.) Some (like Gimp) can even be "scripted" for a more batch-like operation, if you have repetitive processes to apply.
It wouldn't hurt to do a little research and play with them a bit...they may well be what you're looking for (without the arcane aspect of a tool like Imagemagick)
Imagemagick, but that doesn't mean it's good for everything!
