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`

<@U010550J4RZ> Yes I know, but the problem is that the desktop canvas does not have a corresponding message.

<@U015TKX93PD> 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 :-)
