Find and replace colors from .aso palettes

[bluebeezle]

I'm trying to write a script that will take all the colors (using 0-threshold) in the current document found in the first .aso (the swatches of which are sorted in a specific order) and replaces them with the colors from the second swatch. So for example, if I wanted make a darker version of my image, I'd make one palette with #FF0000 red as the first swatch, #0000FF blue as the second swatch, etc, and in the second palette, I'd have dark red as the first swatch, and dark blue as the second swatch, etc. Then all instances of red in the file would be replaced with dark red, all instances of blue with dark blue, etc. And to complicate things further, the files have a timeline, so this would have to be done on every layer on every frame.

Is there a way to do this? Can I read hex colors from an *.aso file? Or will I have to store the colors in another format, like a text file? Is there a way to replace colors on every frame?

Try this script.

Change the code after the comment

// I did not understand what you really need

var file1 = new File("C:/A0/1.aco"); // first color file // comment this line if you want to use the current color

var file3 = new File("C:/A0/3.aco"); // result color file

I should add that I mistakenly called them aso files when they're aco files, but as for your script, this goes a long way towards getting me where I want to go. Thanks!

Hi rbin, I tried running the code, but am getting this error:

the line "set" is not currently available
