A fork of https://github.com/mikepenz/HypnoticCanvas with removed fluff and updates to support the newer Compose Skia API.

Add the library as a dependency to your Kotlin Multiplatform project. Replace VERSION with the desired release (click the badge above to see the latest).

hypnoticcanvas = { module = "dev.brahmkshatriya.hypnoticcanvas:lib", version = "VERSION" }

The library provides a shaderBackground modifier. Use it.

import com.mikepenz.hypnoticcanvas.shaderBackground
import com.mikepenz.hypnoticcanvas.shaders.GlossyGradients

//...
Box(Modifier.fillMaxSize().shaderBackground(GlossyGradients))

You can also take a look at the examples module for more examples.

Custom shaders can be created by implementing the Shader interface.

Texture-style uniforms are supported too. In AGSL/SkSL, declare them as uniform shader and sample them with .eval(...).

override fun applyUniforms(runtimeEffect: RuntimeEffect, time: Float, width: Float, height: Float) {
	super.applyUniforms(runtimeEffect, time, width, height)
	runtimeEffect.setShaderUniform("uWaveform", ImageShader(waveformBitmap))
}

Example shaders included in the library are:

• MeshGradient
• GlossyGradients
• MesmerizingLens
