I am tracing objects with the intent of later adding them to another image. First I trace with free select and then I copy and paste the object to a transparent layer. Then I export to a png and I get the option to save color values from transparent pixels. I don't know whether or not to select this option.
When I zoom in on the pasted object on the transparent layer I see along the edge of the tracing what appears to be partially transparent pixels. If I opt to save color values from transparent pixels will the object blend better when I add the png file to another image?
The way you do it, no.... The transparent layer you copy/paste to is already filled with black (0,0,0) so that's what the pixels you don't change (so, the ones that remain transparent) are set to.And if you don't save the color of transparent pixels, it is set to black. So whatever your choice, the result is the same.
Of course the colors of all other pixels (including the partially transparent ones) is always saved.
