Xamarin Form SkiaSharp SKMatrix transformation

Question

Hi,
I try to solve my problem with SkMatrix in SkiaSharp :

I want to transform my Bitmap1 (corners A, B, C, D) and resize it to my full container (corners 1, 2, 3, 4) with Matrix transform.

(Of course the Bitmap will be a bit distorted ...)

Help of expert would be appreciated ;-)

Thanks

Hi, MisterXamarin-2605. To resize an SKBitmap to fill an SKCanvasView, try using the Resize method.

var resizedBitmap = bitmap.Resize(info, SKBitmapResizeMethod.Box);
canvas.DrawBitmap(resizedBitmap, info.Width / 2 - resizedBitmap.Width / 2, info.Height / 2 - resizedBitmap.Height / 2);
