As a (very) novice Photoshop user, I purchased PanosFX Puzzle Effects which has saved me days in creating the effects I need to use in a major Keynote presentation.
However, I’ve run into a small problem. When exporting each puzzle piece in .png format, each piece has a pixel width white edge. As I don’t want any background for each piece, this creates a bit of an ugly problem as the pieces are put together in Keynote.
How do I eliminate this white line? Is there a better format than .png?
Open each piece in Photoshop separately, then choose Layer / Matting / Defringe and fiddle with the settings under Remove White Border. This will probably work perfectly for you. PNG is the absolutely best format to use in Keynote, as all the transparency will be preserved, along with full-color gradients and other niceties. The only thing better would be PDF, but then, only if it was actually vector art. In pixel-base art, PNG is King!

You can “record” most multi-step processes in Photoshop. But try it out on one or two pieces first, and get your settings figured out. Then open the Window / Actions palette and press Record, open a new piece, run the filter on it, then press Stop. Read the help page on the process of setting up a multi-document run like this, there are some traps waiting for you in terms of saving the updated files, etc. Once you figure it out, you should be able to throw a whole folder of pieces at it, run the Action, and the resulting images will pile up in a new folder. I do this sort of thing once every couple of years, and have to re-learn the process each time.

Arg! I was afraid that would be the answer. Is there a “simple” way to automate that task in a batch process (again Photoshop neophyte user)?
