AndroidNativeCanvas

class AndroidNativeCanvas(canvas: Canvas) : KiteCanvas

KiteCanvas backed by android.graphics.Canvas.

This is the right choice on Android when you don't want Compose: pass a Canvas from your custom View's onDraw(Canvas) override straight into the constructor and the renderer paints into it.

Pair with AndroidPdfBitmapRenderer for the "render a PDF page into a Bitmap" use case.

Blend modes require API 29+ (Paint.setBlendMode). The module's minSdk is 29 to match. See :kitepdf-native build.gradle.kts.
