Photoshop: Trim a photo so it contains no transparent pixels?
Solution 1:
Image > Trim then select Based On: Transparent Pixels
Solution 2:
Using CS6, the following does exactly what is required for me:
- select crop tool
- select 'straighten'
- draw along a known straight line
- the rotation is performed immediately and a suggested crop appears cutting out all the transparent pixels resulting from the rotation.
result: beautiful!
