GPainter Extensions


#1

Guys,

I made some extensions to the GPainter class for the 3.6" BW 128x64 screen.
If someone wants to add to this, just post a msg with your extension method.

Feel free to use in any way you like.

Gus, shall I add this to code.tinyclr.com ?

Usage:


GPainterExtensions paint = new GPainterExtensions();

paint.PrintCentered(0, 30, "Fez Rules"));

Class GPainterExtensions


using System;
using Microsoft.SPOT;

namespace GHIElectronics.Graphics.Simple128x64
{
  class GPainterExtensions : GHIElectronics.Graphics.Simple128x64.GPainter
