AndroidDrawing

This is a porting layer between System.Drawing.Graphics and Android.Drawing.Canvas classes.

Its primary use is in MAUI/Xamarin Android framework.

This layer allows to share the same primitive drawing code between .net Windows Mobile/Windows Phone platforms and Android platform.

AndroidDrawing also contains a trivial implementation of System.Graphics Pen, Color, Brush, Size, SizeF, Rectangle.

FastGraphics implementation (which is default) uses a simple operation batching method. This method increases performance if many simple draw operations are performed on Graphics canvas one by one. Main gain comes from eliminating too many JNI-Java switches.

Usage

 // Optional:
 Graphics.DeviceDPI = android_dpi;

 var g = new Graphics(android_canvas);

 // Optional:
 g.LineWidth = 2;
 g.Flags = Android.Graphics.PaintFlags.AntiAlias;
 g.DrawLine(new Pen(Color.Red), 0,0,100,100);
 g.DrawText(new Pen(Color.Red), 0,0,100,100);
 g.DrawString("Hello Android", new Font("serif", 12, FontStyle.Italic),
                     new Brush(Color.Black), new RectangleF(0,0,100,100));
 g.DrawImage(new Bitmap(100,100), 0, 0);
