Graphics.DrawImage Method (Image, Rectangle, Int32, Int32, Int32, Int32, GraphicsUnit)


Draws the specified portion of the specified Image at the specified location and with the specified size.

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

Type: System.Drawing.Image

Image to draw.

Type: System.Drawing.Rectangle

Rectangle structure that specifies the location and size of the drawn image. The image is scaled to fit the rectangle.

Type: System.Int32

The x-coordinate of the upper-left corner of the portion of the source image to draw.

Type: System.Int32

The y-coordinate of the upper-left corner of the portion of the source image to draw.

Type: System.Int32

Width of the portion of the source image to draw.

Type: System.Int32

Height of the portion of the source image to draw.

Type: System.Drawing.GraphicsUnit

Member of the GraphicsUnit enumeration that specifies the units of measure used to determine the source rectangle.

Exception Condition

image is null.

The srcX, srcY, srcWidth, and srcHeight parameters specify a rectangular portion, of the image object to draw. The rectangle is relative to the upper-left corner of the source image. This portion is scaled to fit inside the rectangle specified by the destRect 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 a destination rectangle in which to draw the image.

  • Creates the coordinates of a source rectangle from which to extract a portion of the image.

  • Sets the unit of measure of the source rectangle to pixels.

  • Draws the image to the screen.

The position of the destination rectangle locates the image on the screen, and the sizes of the source and destination rectangles determine the scaling of the drawn image, and the size of the source rectangle determines what portion of the original image is drawn to the screen.
