[SOLVED] rotating an image in GIMP

newbiesforever · 08-01-2011, 12:48 PM

In GIMP, can I rotate an image by only a few degrees? It's a scanned image of a crooked xerox copy, and I want to straighten it. I see options only for rotating by 90 or 180 degrees.

Use the rotate tool, once you click into a layer a dialog will open for precise rotating. Be sure to set the rotating point at the right place.

Shift+R - rotate tool.

That worked, thank you. What about the canvas that shows at the edges as a result of the image no longer being perfectly aligned with the canvas? I tried a few things, and the two ways I can find to hide the canvas are: (1)crop the edges, (2)Layer-->Transparency-->Remove Alpha Channel (whatever that is). Is there a better way?

If I have to deal with that I usually crop the image. Removing the alpha channel just removes the transparency, so that those free parts just become opaque, but they contain no image information.

Alpha == Opacity
