Hello,
I have a scanned gray scale signature, because of the scan it’s effectively anti-aliased already. However, it’s anti-aliased to the white background it was written on. Is there someway to tell photoshop to convert the different shades of gray to black with a corresponding transparency value (i.e. so that it would be effectively anti-aliased over a transparent background rather than white) as I want to paste it over the top of an image.
I think it would be a pretty simple operation to perform (theoretically) and the only information needed should be that solid color is black anti-aliased to white background so calculate the transparency value to give a particular gray over the white. But whether there is some easy option to do it I’m not sure!
I have tried the Image -> Extract… option. This doesn’t seem to do a perfect job as I tested it by drawing a ‘perfectly’ anti-aliased curve with a paint brush tool onto a white background and then tried to extract it back out off the white, it was ok but far from perfect compared to the original. It seems a lot of fiddling around as well.
Any ideas or suggestions welcome! I need to buy a book on photoshop!
Using photoshop 6.0.1 by the way.
Thanks for any help/suggestions
