Public Sub TransformPoints (destSpace As CoordinateSpace, srcSpace As CoordinateSpace, pts As Point())
Public Sub TransformPoints (destSpace As CoordinateSpace, srcSpace As CoordinateSpace, ParamArray pts As Point())
Parameters
- destSpace
- CoordinateSpace
Member of the CoordinateSpace enumeration that specifies the destination coordinate space.
- srcSpace
- CoordinateSpace
Member of the CoordinateSpace enumeration that specifies the source coordinate space.
Examples
The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e
, 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.
public:
void TransformPointsPoint( PaintEventArgs^ e )
{
// Create array of two points.
array<Point>^ points = {Point(0,0),Point(100,50)};
// Draw line connecting two untransformed points.
e->Graphics->DrawLine( gcnew Pen( Color::Blue,3.0f ), points[ 0 ], points[ 1 ] );
// Set world transformation of Graphics object to translate.
e->Graphics->TranslateTransform( 40, 30 );
// Transform points in array from world to page coordinates.
e->Graphics->TransformPoints( CoordinateSpace::Page, CoordinateSpace::World, points );
// Reset world transformation.
e->Graphics->ResetTransform();
// Draw line that connects transformed points.
e->Graphics->DrawLine( gcnew Pen( Color::Red,3.0f ), points[ 0 ], points[ 1 ] );
}
private void TransformPointsPoint(PaintEventArgs e)
{
// Create array of two points.
Point[] points = { new Point(0, 0), new Point(100, 50) };
// Draw line connecting two untransformed points.
e.Graphics.DrawLine(new Pen(Color.Blue, 3), points[0], points[1]);
// Set world transformation of Graphics object to translate.
e.Graphics.TranslateTransform(40, 30);
// Transform points in array from world to page coordinates.
e.Graphics.TransformPoints(CoordinateSpace.Page, CoordinateSpace.World, points);
// Reset world transformation.
e.Graphics.ResetTransform();
// Draw line that connects transformed points.
e.Graphics.DrawLine(new Pen(Color.Red, 3), points[0], points[1]);
}
