Aakanaar Posted September 8, 2007 Share Posted September 8, 2007 It was working the other night, now.. suddenly.. When i rotate the layer by 90 degree's, instead of a nice crisp clean layer, i get something that looks like i've glausian blurred it. I don't have any idea what's changed. I havn't downloaded any new plugins since it was last working, nor updated the software (it's currently 3.10). I've not made any other changes to the computer. Before it would rotate the layer.. now.. Let me get a screenshot of what i mean. ... Ok.. scratch that.. now suddenly it's working again.. I replicated the problem all morning long, and now when I need it, i can't. There is a bug in there somewhere, not easily reproducable i guess. Consider this just a report.

Aakanaar Posted September 8, 2007 Author Share Posted September 8, 2007 Bah.. now it's doing it again.. argh!! ok.. let me show.. Getting screenshot You can see how the one rotated 180 degree's went nice and sharp.. while the one rotated only -90 degrees went way out of focus. It used to be sharp as well.

Ghost Ranger Posted September 10, 2007 Share Posted September 10, 2007 It has to do with anti-aliasing. When rotating a pic with non-anti-aliased( :AntiAliasingOff: ) pixels, it blurs them, as the pixels are in a grid, so when rotated, half of a pixels might be in one grid section and the other half in another, so it shades them to make it look like it is in only one. I would suggest either enabling anti-aliasing( :AntiAliasingOn: ) or using "flip horizontal/ vertical". Quote Link to comment Share on other sites More sharing options...

That shouldn't have any effect. Rotate/Zoom uses its own sampling method which is separate from the Anti-aliasing( :AntiAliasingOff: / :AntiAliasingOn: ) settings . Are you adjusting anything beside the rotation "Angle"? Edit: What was you image resolution when you were able to reproduce this? I think I might have gotten this to work(not work...)

barkbark00 Posted September 11, 2007 Share Posted September 11, 2007 Repro: Open new canvas at 801px w x 500px h. Draw aliased lines and curves in bottom right corner Rotate/Zoom (Angle set to -180 degrees) Quote Take responsibility for your own intelligence. 😉 -Rick Brewster Link to comment Share on other sites More sharing options...
