[FR] Replace (background) color to transparency

[tfrancois]

Is your feature request related to a problem? Please describe.

Is there was a way to add a feature to take a PNG or JPG source image and replace the default background color with a transparent background or alpha/translucency. If necessary, the default background color can simply be selected using the pixel at the [0,0] x/y coordinate of the source image.

just change the background pixels alpha

Thank you for the quick reply. But how do you that? I need to perform this action programmatically.
