Question

I’m searching for a way to stack two UIImages. I don’t want to simply merge them (add one above another), i rather want to stack their pixel values.
My knowledge ends by getting the data by UIImageJPEGRepresentation(), but that’s not the point. I would need raw image data of both images and create a third image with stacked data.
I really appreciate any help here. :/

Edit:
I’ve talked with a colleague of mine and he noted, that this is something like the screen layer-property in photoshop. Maybe that clarifies what i mean.

Answer 1

I’ve ended up using the same method as fake a long exposure.
