skbitmap encode as stream in maui is not properly working (Android 12 samsung galaxy A10)

Question

 SKBitmap RotateBitmap(SKBitmap bitmap)
    {
        SKBitmap rotatedBitmap = new SKBitmap(bitmap.Height, bitmap.Width);
            using (var surface = new SKCanvas(rotatedBitmap))
            {
                surface.Translate(rotatedBitmap.Width, 0);
                surface.RotateDegrees(90);
                surface.DrawBitmap(bitmap, 0, 0);
            }
        return rotatedBitmap;
    }


SKBitmap photoBitmap = RotateBitmap(SKBitmap.Decode(streamimg));
Stream rotatedStream = SKImage.FromBitmap(photoBitmap).Encode().AsStream();

Getting wrong stream after encoding and when binding the stream to image, getting black screen.

Answer 1

Firstly, please run your code in the android emulator, will you get the same issue?

How did you bind the stream to image? I use following code and android 11 emulator, it is working without any issue.myImage.Source = ImageSource.FromStream(()=>rotatedStream);.

And please make sure you have installed following nugget packages in your project.
