engineer 2011 Mar 1, 2011 6:41 AM (in response to c.pfaffenbichler)Thanks,
I will check the Image Interpolation when I get home.
What setting would you suggest?
I am doing "digital scrapbooking" type layouts where photos are not always straight up and down.
I looked in the help file and Bicubic Smoother looked like what it might work best for this application. Does this seem right to you?
Thank you,
John

engineer 2011 Mar 1, 2011 6:44 AM (in response to Semaphoric)I used the navigator to view it a 35% and then changed to various sizes. Big and small they all looked generally the same.

Bill Hunt Mar 1, 2011 9:04 AM (in response to engineer 2011)John,
One consideration is the degree/angle of your Rotation. If you are working in 90 degree increments, all will be better, than if you Rotate to other angles, as the pixels are square, and with other angles, there will be an issue, as you are now filling partial pixels - the other option is to fully fill all square pixels, but allow them to "step," creating "jaggies." I'd take a bit of Transparency in part of pixels, over "jaggies," myself.
Good luck, and hope that you get what you want. I would also think that Bicubic Smoother will look better, but it's easy to try Bicubic Sharper and judge the for yourself.

It's a known fact that it can look tremendously pixelated during the operation, as the algorithms are optimized for speed. But the results should be clean after the Transform is completed.
Maybe the preview during Transform is something Adobe can clean up in an upcoming version that relies more on OpenGL.
I would suggest leaving the interpolation setting at just plain Bicubic for best overall results.

engineer 2011 Mar 1, 2011 10:10 AM (in response to Noel Carboni)After it is complete.
I have saved the file closed it and reopened it. Then I tried to do something similar in a new file and got the same results (I was hoping a bad setting would be reset in a new file.)
Thanks-

10. Re: Rotating a layer
engineer 2011 Mar 1, 2011 10:28 AM (in response to Noel Carboni)You might be right because I had a trial of cs5 on my work computer and tried rotating a layer and was happy with the results.
My home computer with CS4 is the one not giving me good results. I will try to look at this tonight. I can see if my video driver has an update.
Thanks

11. Re: Rotating a layer
engineer 2011 Mar 2, 2011 5:55 AM (in response to Noel Carboni)I think your right about the video card. If I view the psd file at 100% and pan around it looks ok, but if I zoom in or out it looks bad. If I make a jpg out of the psd the jpg looks good in other programs.

12. Re: Rotating a layer
Noel Carboni Mar 2, 2011 8:59 AM (in response to engineer 2011)Check to see if OpenGL is enabled: Look in the Edit - Preferences - Performance dialog.
I suspect it is not, if you're seeing "rough" resampling. There's some good info on Adobe's site about getting your GPU to work best:

Thanks for the references.

14. Re: Rotating a layer
Noel Carboni Mar 2, 2011 12:04 PM (in response to engineer 2011)That could mean you need a video driver update, or in the worst case possibly a new video card. What model do you have?
