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

public void DrawImage(
	Image image,
	RectangleF rect
)

Parameters

image
Type: System.Drawing.Image

Image to draw.

rect
Type: System.Drawing.RectangleF

RectangleF structure that specifies the location and size of the drawn image.

Exception Condition
ArgumentNullException

image is null.

The image represented by the image object is scaled to the dimensions of the rect rectangle.

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 rectangle in which to draw the image.

  • Draws the image to the screen.

The position of the rectangle locates the image on the screen, and the original size of the image and the size of the rectangle determines the scaling of the drawn image.

public void DrawImageRectF(PaintEventArgs e)
{

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

    // Create rectangle for displaying image.
    RectangleF rect = new RectangleF(100.0F, 100.0F, 450.0F, 150.0F);

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