Example of

ViewIntoBitmap

method

Rotating or Flipping a Bitmap

13

Use the

MungeBitmap

function (page 10-22) to perform various bitmap operations

such as rotating or flipping the bitmap. These operations are destructive to the bitmap
passed as an argument to this function; the bitmap is modified in place and the
modified bitmap shape is returned. Figure 13-11 illustrates how the

MungeBitmap

function works. See "Using Bitmaps" (page 13-17) for a code example.
