Graphics.DrawImage Method (Image, Point[])
Assembly: System.Drawing (in system.drawing.dll)
The destPoints parameter specifies three points of a parallelogram. The three Point structures represent the upper-left, upper-right, and lower-left corners of the parallelogram. The fourth point is extrapolated from the first three to form a parallelogram.
The image represented by the image parameter is scaled and sheared to fit the shape of the parallelogram specified by the destPoints parameters.
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 an image from a JPEG file SampImag.jpg in the folder of the example.
-
Creates points that define a parallelogram in which to draw the image.
-
Draws the image to the screen.
The position of the parallelogram locates the image on the screen, and the size of the original image and the size and shape of the parallelogram determines the scaling and shearing of the drawn image.
private: void DrawImagePara( PaintEventArgs^ e ) { // Create image. Image^ newImage = Image::FromFile( "SampImag.jpg" ); // Create parallelogram for drawing image. Point ulCorner = Point(100,100); Point urCorner = Point(550,100); Point llCorner = Point(150,250); array<Point>^ destPara = {ulCorner,urCorner,llCorner}; // Draw image to screen. e->Graphics->DrawImage( newImage, destPara ); }
