Exporting transparent image without background box
Hi All,

This is really frustrating...

I removed all white from an image and am trying to export it to a png. I have tried deselecting the "save background color" and "save color values of transparent pixels" and other options however It always exports with this faint box around it... Check it out here:

and here:

Can someone tell me what I am doing wrong?

Thanks Smile

Good thing but you should protect the inside of the lock with a selection: fuzzy select the background, and grow the selection by one pixel to include the edge pixels of the lock. Then do color-to-alpha, and it won't apply to the inside of the lock.

You didn't do anything wrong, you just assumed that the background was uniform when it wasn't, so C2A left some faintly opaque pixels. In the steps above, after the C2A, shrink the selection by two pixels (original background shrunk by one pixel) and [delete].

Perfect answer. Thank you. Looks awesome now Smile
