Transforming the Drawing

These instructions assume that you have completed the Scaling the Coordination task.

This topic uses the DrawEllipse method to draw an ellipse and calls the ResetTransform method to reset the transform space. A new transform space is specified by setting the Transform property.

Before you reset the transformation and multiply the drawing, import the Drawing2D and C1Flash namespaces; add the following code to the top of the form:

To write code in Visual Basic

Visual Basic	Copy Code
Imports System.Drawing.Drawing2 Imports C1.C1Flash

To write code in C#

C#	Copy Code
using System.Drawing.Drawing2D; using C1.C1Flash;

In the Form_Load event handler, you will add code to reset the transformation and multiply the drawing. Complete the following steps:

Add the following code to the Form_Load event, placing it after the code that sets the DrawEllipse, FillEllipse, RotateTransform, and ScaleTransform properties but before the RenderToFile method:

To write code in Visual Basic

Visual Basic	Copy Code
' Resets the coordinate Me.C1FlashCanvas1.ResetTransform() Dim i As Integer For i = 1 To 11 Me.C1FlashCanvas1.DrawEllipse(Pens.Red, rect) ' Change the Transform Dim m As Matrix = Me.C1FlashCanvas1.Transform m.Shear(0.15F, 0.15F) Me.C1FlashCanvas1.Transform = m Next i

To write code in C#

Save and run the application.

C#	Copy Code
// Resets the coordinate this.c1FlashCanvas1.ResetTransform(); for(int i = 1; i < 12; i++) { this.c1FlashCanvas1.DrawEllipse(Pens.Red, rect); // Change the Transform Matrix m = this.c1FlashCanvas1.Transform; m.Shear(0.15F, 0.15F); this.c1FlashCanvas1.Transform = m; }

This topic illustrates the following:

Your transformed matrix drawing will look like the following image:
