What are some advanced techniques in Skia graphics?

Skia offers several advanced techniques like custom shaders, path effects, and advanced image filters. Would you like to know more about any specific technique?

Can you explain how to create custom shaders?

Certainly! Custom shaders in Skia can be created using GLSL. You define your shader code and compile it, then use it in your drawing operations. Would you like a code example?

Yes, please provide a simple example of a custom shader.

Here's a basic example of a fragment shader that inverts colors:

#version 120
void main() {
    vec4 color = texture2D(u_texture, v_texCoord);
    gl_FragColor = vec4(1.0 - color.rgb, color.a);
}

This shader inverts the colors of the texture applied. Would you like to learn about integrating this shader into a Skia project?

That would be great! How do I integrate it?

To integrate the shader, you need to create a SkShader object using the compiled GLSL code and then apply it to your paint object before drawing. Would you like a step-by-step guide?
