Skia custom brushes

[Adrian F]

Hi, I'm trying to implement a drawing application using Visual Studio's Window Forms Applications. I decided to go with Skia for the drawing logic and I have been struggling to implement 'custom brushes'. Essentially I want to be able to create different types of brushes like the Microsoft Paint program, but I haven't been able to find much information online. The best I've been able to do is use an SKShader ( with a png bitmap ), in the SKPaint object and then using this paint object in the Canvas.Draw() method, but the behavior is more like the bitmap is being revealed rather than actually 'drawing' with the bitmap. I hope that makes sense and I would appreciate any advice that'll point me in the right direction (if this is even possible with Skiasharp), thanks!

This old conversation might be relevant to what you want:

It's close. From what I can tell from the conversation and the images provided, when you draw a line using the noise mask, drawing would essentially reveal the mask underneath. I want it so that I actually draw with the noise mask. Instead of revealing I would like it draw with the noise mask texture. Otherwise, I think if you drew on the entire canvas it would look exactly like the noise mask image, correct me if I'm wrong.
