[iOS] Canvas.DrawImage and Canvas.Rotate cut Image

[ptittof57]

Description

The following code have a strange behavior when rotation value is animated on iOS device only. Image seems to move inside a rectangle of image initial width and height and it's cut and not rendered like expected. On iOS and Net-7.0, image get out of red border only for the reproduction project. But in my personal project this is the same behavior, canvas.DrawImage + canvas.Rotation cut image for both Net-7.0 and Net-8.0. Everything works like expected in Android physical device and simulator. Check print screens to see the results. I added a testing project with rotation bind into a value that change every 200ms to a better view.

public class ImageDrawable : IDrawable
 {
     private IImage _image;

     public void Draw(ICanvas canvas, RectF dirtyRect)
     {
         if (this._image == null)
         {
             Assembly assembly = this.GetType().GetTypeInfo().Assembly;
             using (Stream stream = assembly.GetManifestResourceStream("ImageRotate.Resources.Images.dotnet_bot.png"))
             {
                 this._image = PlatformImage.FromStream(stream);
             }
         }

         canvas.DrawImage(this._image, 0, 0, this._image.Width, this._image.Height);
     }
 }

Android is OK

iOS Simulator Net-7.0 (out of red border)

iOS Physical device image is cut Net-8.0

Steps to Reproduce

Run the reproduction project on iOS 17 device or simulator

Link to public reproduction project repository

https://github.com/ptittof57/MAUI-ImageRotate

Version with bug

8.0.3

Is this a regression from previous behavior?

Seems it was better with Net-7.0 but it was running out of red border.

Last version that worked well

Net-7.0 image was not cut

Affected platforms

iOS

Affected platform versions

iOS 17, Net 7 and Net 8

Did you find any workaround?

I used Image.Rotation on iOS and this worked and both iOS and Android
