Need Help To Modify This Script

jmarkt · Post by **jmarkt** » Tue Jan 13, 2015 3:51 am

The script below modifies PNG format clipart by filling current transparent areas within the clipart to black, which is desired. The black lines are also converted to white, which I would like to modify so that that white would be "knocked out", or made transparent. Here is a link to reflect current and desired: https://jumpshare.com/b/Rxbfz8Xr42NUiBOwEuTS

I think you should restructure the process.
First create the Selection that you currently use for the black Layer, then load the Red Channel, but instead of SelectionType.REPLACE use DIMINISH and create only one Layer.

It absolutely did, pfaffenbichler! Helped my learning curve as well. Thanks again!
