I am working on 2D rendering in Avalonia and have drawn lines, circles, and other entities using the DrawingContext in the control's Render override method. I am using the Matrix class for scaling and Y-axis translation.

I can select a specific entity, such as a line or circle, without using the matrix transformation. However, when applying the matrix, the selection does not work correctly because the points do not match.

    public override void Render (DrawingContext context) {
   base.Render (context);

   
  
   // 2D Render Matrix
   this.renderMatrix = _2DView.GetMatrix ();

   // Draw Scene
   using (context.PushTransform (this.renderMatrix)) {
      if (this.Entity == null) return;
      foreach (var entity in this.Entity!) {
         defPen = entity.IsSelected ? new (Brushes.Red, 2) : new (Brushes.White, 1);
         EntityDrawerVM.DrawEntity (context, entity, this.renderMatrix, defPen);
      }
   }

}



  Convert screentoworldpoint:
 private Avalonia.Point ScreenToWorld (Avalonia.Point p) {
    return new Avalonia.Point (
               (p.X * this.renderMatrix.M11) + (p.Y * this.renderMatrix.M21) + this.renderMatrix.M31,
               (p.X * this.renderMatrix.M12) + (p.Y * this.renderMatrix.M22) + this.renderMatrix.M32);
 }
