How do I control the opacity of individual pixels?
Hello everyone,
I searched on the internet but found nothing.
I want to control each pixel’s opacity depending on another pixel’s color on another layer.
For example: if a pixel in a layer 1 has the same color (hsla) as the pixel in layer 2, the pixel opacity of layer 1 becomes 0. Otherwise the opacity is 100.
I don’t know if this is actually possible.
Thanks a lot in advance,

I think you’d need to create a plugin to do that.

Hi Dan, Thanks.
Do you know any good website or tutorial that you can suggest to me on how to create a plugin?
I know it’s not that easy. But I’m kind of desperate to have this kind of control.

The best tutorial I know of is the SDK documentation itself. It sort of takes you through what you need to do to convert one of the example plugins to be your own. That part’s not too tough. However, there’s a pretty steep learning curve on figuring out how to make it do something different (like in your case–adding a layer control, checking out that layer, and getting pixels from it).
It’s actually quite a bit of fun figuring it all out and getting a new plugin to work, it’s just that first one will take quite a while.
