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.
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.
