Graphics.DrawImage Method (Image, PointF, RectangleF, GraphicsUnit)
Draws the specified portion of the specified Image at the specified location and with the specified size.
Assembly: System.Drawing (in System.Drawing.dll)
member DrawImage : image:Image * destPoints:PointF * srcRect:RectangleF * srcUnit:GraphicsUnit -> unit
- Type: System.Drawing.PointF
Array of three PointF structures that define a parallelogram.
- Type: System.Drawing.RectangleF
RectangleF structure that specifies the portion of the image object to draw.
image is a null reference (Nothing in Visual Basic).
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 srcRect parameter specifies a rectangular portion of the image object to draw. This portion is scaled and sheared to fit inside the parallelogram specified by the destPoints parameter.
Creates an image from a JPEG file SampImag.jpg in the folder of the example.
Creates points that define a destination parallelogram in which to draw the image.
Creates 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 parallelogram locates the image on the screen, the size of the source rectangle and the size and shape of the destination parallelogram determines the scaling and shearing of the drawn image, and the size of the rectangle determines what portion of the original image is drawn to the screen.
