A null +reference or invalid value was found. +in <0x00084> System.Drawing.GDIPlus:CheckStatus (Status status) +in <0x0004e> System.Drawing.Drawing2D.Matrix:.ctor (RectangleF rect, +System.Drawing.PointF[] pa) +in (wrapper remoting-invoke-with-check) +System.Drawing.Drawing2D.Matrix:.ctor +(System.Drawing.RectangleF,System.Drawing.PointF[]) +in <0x0017f> MatrixBug.Program:Main (System.String[] args) + +On this line of code: +Matrix m = new Matrix(new RectangleF(0.0f, 0.0f, 100.0f, 100.0f), new +PointF[] { new PointF(10.0f, 10.0f), new PointF(20.0f, 10.0f), new +PointF(10.0f, 20.0f) }); + +This constructor works fine under MS.Net 2.0. + +Steps to reproduce the problem: +Compile the above line. A small test program is attached, as well. + +Actual Results: +Exception. + +Expected Results: +Correctly constructed Matrix. + +How often does this happen? +Always. + +Additional Information: +I'm not an expert in Mono or GDI Plus, but it looks like the Mono +constructor is attempting to pass the rectangle and points directly to GDI +Plus, but it looks to me like the .Net class and the GDI Plus class have +constructors that look similar but actually do different things. Even given +that, I'm not sure why this exception would arise, though. _______________________________________________ mono-bugs maillist - [email protected] http://lists.ximian.com/mailman/listinfo/mono-bugs
