Graphics.DrawImage Method (Image, Rectangle, Single, Single, Single, Single, GraphicsUnit, ImageAttributes)

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)

public void DrawImage(
	Image image,
	Rectangle destRect,
	float srcX,
	float srcY,
	float srcWidth,
	float srcHeight,
	GraphicsUnit srcUnit,
	ImageAttributes imageAttrs


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.Single
The x-coordinate of the upper-left corner of the portion of the source image to draw.
Type: System.Single
The y-coordinate of the upper-left corner of the portion of the source image to draw.
Type: System.Single
Width of the portion of the source image to draw.
Type: System.Single
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.
Type: System.Drawing.Imaging.ImageAttributes
ImageAttributes that specifies recoloring and gamma information for the image object.


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 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 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 original image to the screen.

  • Creates an additional rectangle in which to draw an adjusted image.

  • Creates and sets the attributes of the adjusted image to have a larger-than-usual gamma value.

  • Draws the adjusted image to the screen.

For the original, unadjusted destination rectangle, the position 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.

private void DrawImageRect4FloatAttrib(PaintEventArgs e)

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

    // Create rectangle for displaying original image.
    Rectangle destRect1 = new Rectangle(100, 25, 450, 150);

    // Create coordinates of rectangle for source image.
    float x = 50.0F;
    float y = 50.0F;
    float width = 150.0F;
    float height = 150.0F;
    GraphicsUnit units = GraphicsUnit.Pixel;

    // Draw original image to screen.
    e.Graphics.DrawImage(newImage, destRect1, x, y, width, height, units);

    // Create rectangle for adjusted image.
    Rectangle destRect2 = new Rectangle(100, 175, 450, 150);

    // Create image attributes and set large gamma.
    ImageAttributes imageAttr = new ImageAttributes();

    // Draw adjusted image to screen.
    e.Graphics.DrawImage(newImage, destRect2, x, y, width, height, units, imageAttr);
