Graphics.TransformPoints Method (CoordinateSpace, CoordinateSpace, Point[])

 

Transforms an array of points from one coordinate space to another using the current world and page transformations of this Graphics.

Namespace:   System.Drawing
Assembly:  System.Drawing (in System.Drawing.dll)

member TransformPoints : 
        destSpace:CoordinateSpace *
        srcSpace:CoordinateSpace *
        pts:Point[] -> unit

Parameters

destSpace
Type: System.Drawing.Drawing2D.CoordinateSpace

Member of the CoordinateSpace enumeration that specifies the destination coordinate space.

srcSpace
Type: System.Drawing.Drawing2D.CoordinateSpace

Member of the CoordinateSpace enumeration that specifies the source coordinate space.

pts
Type: System.Drawing.Point[]

Array of Point structures that represents the points to transformation.

The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, which is a parameter of the Paint event handler. The code performs the following actions:

  • Creates two points and draws a blue line between them.

  • Sets the world transform to translate by amounts 40 in the x direction and 30 in the y direction.

  • Transforms the points from world coordinates (World) to page coordinates (Page).

  • Resets the world transformation to the identity.

  • Draws a red line between the transformed points.

The result is a blue line and a translated red line below it.
