Skiasharp: [BUG] iOS OutOfMemory crash when SKCanvasView height or width less than 1
This situation may occur when SKCanvasView involved in animation
For example:
var ani = new Animation(x => _canvas.HeightRequest = x,_open ? 100 : 0,_open ? 0 : 100);
ani.Commit(_stack, "sdfs", length: 2000);
Demo project is attached
- Version with issue: 1.68.0
- IDE: Visual Studio 15.9.3
- iOS: 12.2.1.11
I work around this issue added the custom renderer:
`[assembly: ExportRenderer(typeof(SKCanvasView), typeof(CoreXF.iOS.MySKCanvasViewRenderer))]
namespace CoreXF.iOS
{
public class MySKCanvasView : SkiaSharp.Views.iOS.SKCanvasView
{
public override void Draw(CGRect rect)
{
if(rect.Height < 1 || rect.Width < 1)
{
Debug.WriteLine($"Canvas {rect.Height}x{rect.Width}, Bounds {Bounds.Height}x{Bounds.Width}");
Debug.WriteLine($"Skip !!");
return;
}
base.Draw(rect);
}
}
public class MySKCanvasViewRenderer : SKCanvasViewRenderer
{
public MySKCanvasViewRenderer() : base()
{
}
protected override SkiaSharp.Views.iOS.SKCanvasView CreateNativeControl()
{
return new MySKCanvasView();
}
}
}
Log for this renderer :
[0:] Canvas 0.5x44, Bounds 0.479999999999997x44
[0:] Skip !!
