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 Sub DrawImage (
	image As Image,
	destPoints As PointF()
)

Parameters

image
Type: System.Drawing.Image

Image to draw.

destPoints
Type: System.Drawing.PointF()

Array of three PointF structures that define a parallelogram.

Exception Condition
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 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 Sub DrawImageParaF(ByVal e As PaintEventArgs)

    ' Create image.
    Dim newImage As Image = Image.FromFile("SampImag.jpg")

    ' Create parallelogram for drawing image.
    Dim ulCorner As New PointF(100.0F, 100.0F)
    Dim urCorner As New PointF(550.0F, 100.0F)
    Dim llCorner As New PointF(150.0F, 250.0F)
    Dim destPara As PointF() = {ulCorner, urCorner, llCorner}

    ' Draw image to screen.
    e.Graphics.DrawImage(newImage, destPara)
End Sub
