Display part of a bitmap. See also draw-bitmap.

      source : bitmap% object

      color = black : color% object

  The xsrc, xsrc, width, and height arguments specify a rectangle in the source bitmap to copy to this device context.

  The xdest and ydest arguments are in DC coodinates and may be scaled, but the source bitmap is never scaled as it is copied. Thus, if the DC has a scaling factor of 2, the destination width in DC units is width/2.

  See draw-bitmapfor information about style and color.
