1. Re: Resizing An Image Yields Transparent Pixels On Edge
Chris Cox May 17, 2010 12:15 PM (in response to Shan-Dysigns)The image is on a layer, and outside the edge of that layer everything is transparent (there could also be other image data out there as well, depending on how the document was created).
So, when you resample, some of the transparent values get combined with the image data, resulting in some partially transparent pixels on the edges.
It's an unavoidable problem as long as you have layers involved.

Shan-Dysigns May 17, 2010 1:15 PM (in response to Chris Cox)Thanks for responding.
So, you are saying this is just the way the sofware works and there isn't a (easy) way around it?
I supposed I can create an action to crop the image by 1 pixel after I resize it (assumming exact pixel dimensions aren't required). I'm using CS 4. I assume (like I said above about this being the nature of the software), this issue still exists in CS 5?
The solution is more manual than I would hope for.
Thanks again for the reply.

Yes (or more like "that's the way math works, and there is no way around that").
Again, that "issue" exists as long as you have transparency and allow for data to extend beyond the document boundary.
It has been there a long time, and will continue to be there -- because it is not a bug, but an unavoidable fact when doing resampling with transparency involved.

Noel Carboni May 17, 2010 10:11 PM (in response to Shan-Dysigns)In short: Flatten your image before resizing, or make sure the image is on the background layer.
