Hi all,
I'm new to the forum! I have searchied on the forum for a solution but I'm a newbie so I don't even know how to formulate my question properly. What I'm trying to do is the following:
I have a png file of a fractal triangle. The pixels in the png are all white and the background is transparent (in the picture below I have added a black background in Affinity Photo 2 so that the white pixles can be seen).
Next I would like to recolor the white dots only with a gradient ranging from light blue at the edges of the large triangle to black (or transparent) in the center of the large triangle.
How can I do this?
I have tried the gradient tool but I can't figure out how to do this. Reading different instructions on similar (?) topices I imagine that I want to have a gradient fill (light blue to black/transparent) while protecting the alpha so that only the white pixels are affected and not the background.
Any suggestions?
Br,
Fredrik
