Transform interpolation has changed - any fix?

I recently had to re-do some work that had been done earlier with PS7 which requires distorting a screen dump. Doing this under PSCS resulted in a very different-looking image, noticeably more jaggy than the PS7 result. You can compare at

I notice that under Image>Image Size... there are now two variants of Bicubic interpolation (Smoother and Sharper). Using this function with either option does not change my results using Transform (the Smoother/Sharper setting isn't remembered anyway), and I can find no setting for a default interpolation method in Preferences.

Any ideas for a workaround?

I'd look at your comparison GIF image, Allen, but the couple times I tried resulted in connection timeouts.

Are you sure you posted the URL correctly? I tried adding "www." where appropriate....that didn't help.

Allen - you use preferences to set the default for other transforms. It's in the first panel of preferences, right where the manual says it should be.

And both versions you posted have some aliasing. (and you don't say which is which)

I had a similar experience.

Turned out that 'before' and 'after' canvases were created at different resolutions.

Screen, Canvas, and printer resolution - more is not always better. I always cropped the screen dump so I ended up with a smaller image that I had to enlarge. If the area of interest was captured at 800 x 600 screen rez, I may end up with only 300-400 pixels of width that need to print out 4" wide at 300 dpi. Stretching 300 pixels to fill 1200 pixel holes is ugly.

Quite right, Chris. Didn't see it. Going to the smoother bicubic replicates the former default setting. Thanks.
