hey guys, i remember having a photoshop action that takes a selection, grabs the pixels around it's edge, and duplicates them out around the selection, giving each selection island a pixel width of padding. anyone know what i'm talking about, and where i can find this badboy?
var padding:int = 4; duplicate the layer, add a gaussian blur filter with {padding:int} amount. No duplicate that new layer like 10 times and merge them together (ctr + j). Lastly put this merged layer under your original and you should have a extended pixel padding size of {padding:int} pixels.
Select > Modify > Expand by 1 pixel ... is what you're after? or Border..? Hard to tell from your wording. But try both and record the action yourself..
