Problem pasting images which contain alpha into a grid in a larger image in Photoshop

Recommended Posts

Hello. I have 64 100x215 pixel images which I need to paste into a 800x1720 pixel 8x8 gridded image. I have created the grid fine using guides and I have selected 'Snap to guides' however I have come into a problem. The 64 images that I am copying and pasting into the grid contain mainly alpha information. i.e. there is a lot of nothing in them especially around the edges. When I do 'select all' on the sources image I see a dashed black line around the rectangular edge of the image as I would expect, but when I then copy and paste this into the larger image I cannot get the image to snap properly. For some reason Photoshop is making the Bounding Box of the pasted layer just outside the non-transparent area in the source selection instead of being the whole 100x215 area. Can anybody tell me how I can paste a selection which contains alpha at the borders into another image whilst retaining the full boundary of the original selection? Kind regards, Mark Coleman

I have had troubles pasting alpha channels from one image into another before as well. 'Select All' doesnt grab the alpha channel. You need to physically go to the Channels tab to selecta all channels. In other words 'Select All' will grab the RGB channels. Just Shift + Select the alpha channel too (You will see the alpha 'bleed' through the image in a pinkish tone. Then go about your pasting.

Hope that helped.
