Working on it! any way I coulden't use the diagonal but think i give a visual better solution.
Now Im thinking also in a tool to rotate...
Cheers, Jabier.

Nice idea Martin... You could also avoid the clipping problem by taking the diagonal measurement of the current canvas view and use it as the height and width, making a square preview that extends beyond the borders of the preview from the center, so you never see any clipping during rotation.

Realy there is "realtime" but the draw need to be re-rendered so in complex objects you need to wait. Seems dificult to solve in the future without taking a bitmap image of current desktop and realtime "phantom" over real draw. but this seems not a good idea to me.
No need for phantom, just take the pixels off the canvas and rotate them in real time using a non-accurate method (i.e. the fast one).
That should provide enough in-between for mouse actions. Only when the rotation has been stable for a second or two does it need to be re- rendered.
I know this means there's going to be clipping edges, but I don't think it's going to matter as much as not being able to /see/ what the rotation looks like while it's being rotated because of some complex path, filter or pattern.
