It's not impossible, but PS simply has no algorithms to detect isolated islands that meet specific criteria. I vaguely remember one of the lesser known programs having a feature to muve such stuff without creating selections, but I'm not sure if it was PD Pro/ Project Dogwaffle or an even more esoteric one... It#s realyl not a matter of vector vs. pixel, PS simply doesn't have the code for it.
Many thanks for the answer.
I have to clarify my question. I wasn’t precise enough, it’s a little bit different.
Given: I have individual image coordinates for a set of locations.
Wanted: A possibility to position the cursor sequentially at those image location by the means of an external script or procedure.
Thanks for any help.
