Graphics.DrawImage Method (Image, Point, Rectangle, GraphicsUnit, ImageAttributes)
Draws the specified portion of the specified Image at the specified location.
Assembly: System.Drawing (in System.Drawing.dll)
member DrawImage : image:Image * destPoints:Point * srcRect:Rectangle * srcUnit:GraphicsUnit * imageAttr:ImageAttributes -> unit
- Type: System.Drawing.Rectangle
Rectangle structure that specifies the portion of the image object to draw.
- Type: System.Drawing.GraphicsUnit
Member of the GraphicsUnit enumeration that specifies the units of measure used by the srcRect parameter.
image is a null reference (Nothing in Visual Basic).
The destPoints parameter specifies three points of a parallelogram. The three Point 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 parallelogram in which to draw the image.
Creates a rectangle to select the portion of the image to draw.
Sets the graphics drawing unit to pixel.
Draws the original image to the screen.
Creates an additional parallelogram 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 parallelogram, the position locates the image on the screen, and the size of the rectangle and the size and shape of the parallelogram determines the scaling and shearing of the drawn image.
