The following code, copied from MSDN article "Using Matrix Transformation in
System.Drawing" creates an OutOfMemoryException when creating the Matrix.

The downloaded MSDN source code works fine.

Any ideas please? Thanks a lot!

Imports System.Drawing.Drawing2D

Public Class Form1
Inherits System.Windows.Forms.Form

'define the application coordinate range
Private mMinX As Double = -5.0
Private mMaxX As Double = -5.0

Private mMaxY As Double = mMaxX
