Description Goran 2005-10-22 10:23:38 UTC 
Currently the "R" or "]" command performs lossy transformation to the right. 
I would like to have a keyboard shortcut to the lossless transform.
 - or - have the lossless transform as the default action!

Other information:
I use gthumb to view my digital photos, and often I need to rotate photos.

Patch to development branch

This patch changes the actions of the "[" and "]" shortcuts to do a lossless
rotation instead of a lossy rotation when in browse mode.

problem is the "lossless" transform isn't really lossless

(I dont have a recent version of gthumb on this machine, IIRC the lossless rotation changes the original file, overwriting it with the new version.  There is a small possibility I am not remembering correctly but I'm pretty gthumb worked that way.)
I would be very worried about making it easier for people to use the lossless transform feature without knowing what they were doing and accidently lose edge pixels.  Some people feel very strongly about not damaging their originals which they use like negatives and only make chagnes on a copy.  

Whatever you decide be careful to consider the risks.
