chroma key Jscript operation? - RealWorld forums

i have an unlayered image i need to chroma key to make transparent but i cant find a function for it also I cant program AT ALL. so just type it in as your comment or something and i'll copy and paste and stuff.

Wouldn't the floodfill tool with tolerance set to 0 be sufficient?

thanks, but not exactly what I'm looking for.
I have this graphic (and lots of other ones) that I got off the web:
(converted to cursor for easy showing)
as you can see, it smoothly blends with the lighter color. instead of blending with the other color,
I want it to blend with the color for complete transarency.

I see. Unfortunately, this is not a trivial task. Reversing the smoothly blended edges is not an unambiguous operation in a general case. One color can be obtained by more than one pair of colors. I'll eventually try to solve this at least for some cases, but it is going to take time.

You may try to use the Effect->More effect->Remove hue command for now. It may help in some cases.

ah. well, thanks in advance, for your efforts at the least. and btw this could be a neat feature for future programs to include.

On second thought, that worked great! all I had to do was up the opacity after removing the background. <-- hey, maybe there's something?

It works in some cases, but it is not a 100% solution. It needs some more work.
