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

public:
void DrawImage(
	Image^ image,
	int x,
	int y,
	int width,
	int height
)

Parameters

image
Type: System.Drawing::Image^

Image to draw.

x
Type: System::Int32

The x-coordinate of the upper-left corner of the drawn image.

y
Type: System::Int32

The y-coordinate of the upper-left corner of the drawn image.

width
Type: System::Int32

Width of the drawn image.

height
Type: System::Int32

Height of the drawn image.

Exception Condition
ArgumentNullException

image is null.

The rectangle defined by the x, y, width, and height parameters determines the position and size of the drawn image.

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 the position and size of 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 size of the original image and the size of the rectangle determines the scaling of the drawn image.

public:
   void DrawImage4Int( PaintEventArgs^ e )
   {
      // Create image.
      Image^ newImage = Image::FromFile( "SampImag.jpg" );

      // Create coordinates for upper-left corner.
      // of image and for size of image.
      int x = 100;
      int y = 100;
      int width = 450;
      int height = 150;

      // Draw image to screen.
      e->Graphics->DrawImage( newImage, x, y, width, height );
   }
