Hi Nadia, This made me think it would be a nice addition to the "colour to alpha" to provide a "Select" parameter which has the options: - By colour (behaviour as it is now) - Top Left - Top Right - Bottom Left - Bottom Right This makes the action more flexible for batch processing images with different colours. What do you think? Stani

If they are the same, make it transparent, otherwise leave it be. This obviously only works if nothing in the foreground is colored the same as the background, but I have had good success with this sort of method in the pygame world for making sprites. _______________________________________________ Mailing list: https://launchpad.net/~phatch-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~phatch-dev More help : https://help.launchpad.net/ListHelp
