The Android canvas has a method drawBitmapMesh . I can’t find this, or any equivalent method, in the Compose canvas, so that I could use that on desktop too. I have to render my images distorted, so that I can accommodate to different projections of my map-tiles.

You can access the platform canvas by calling nativeCanvas on the compose canvas instance which will return an android.graphics.Canvas for Android and the desktop canvas. You can then call the corresponding methods directly on it.

Under the hood Android uses SkCanvas::drawVertices and `SkShader::CreateBitmapShader`:

So I think you can implement drawBitmapMesh using pure Compose androidx.compose.ui.graphics.Canvas.drawVertices and androidx.compose.ui.graphics.ImageShader

@Nader Jawad Yes I know, but the problem is that the desktop canvas does not have a corresponding message.

@Igor Demin Thanks, that gives me some hope but I will have to leave that exercise to a later time when I (hopefully) understand the whole system a little bit better :-)
