Graphics.DrawImage Method (Image, PointF[])

Draws the specified Image at the specified location and with the specified shape and size.

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

public void DrawImage(
	Image image,
	PointF[] destPoints
)

Parameters

image
Type: System.Drawing.Image

Image to draw.

destPoints
Type: System.Drawing.PointF[]

Array of three PointF structures that define a parallelogram.

ExceptionCondition
ArgumentNullException

image is null.

The destPoints parameter specifies three points of a parallelogram. The three PointF 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 object is scaled and sheared to fit the shape of the parallelogram specified by the destPoints parameter.

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 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 DrawImageParaF(PaintEventArgs e)
{

    // Create image.
    Image newImage = Image.FromFile("SampImag.jpg");

    // Create parallelogram for drawing image.
    PointF ulCorner = new PointF(100.0F, 100.0F);
    PointF urCorner = new PointF(550.0F, 100.0F);
    PointF llCorner = new PointF(150.0F, 250.0F);
    PointF[] destPara = {ulCorner, urCorner, llCorner};

    // Draw image to screen.
    e.Graphics.DrawImage(newImage, destPara);
}
