With the ShowRegion functions, which are based on code supplied by WalderMort, it is possible to show the HRGN in black on the default background, or if a background image is supplied as either a HBITMAP or HDC the HRGN will be shown by inverting the pixels of the background image that are within the supplied HRGN. The image is drawn three times: ILD_NORMAL on top, ILD_TRANSPARENT in the middle, and the bottom is drawn using the custom ILD_* flags parameter. Specifying -1 as the index will draw the entire image list. The index may be -1, or a legal index for the image list. They are the image list's handle, the index of the image in the list, and a custom ILD_* display flag. The ShowImageList() function, which was originally written by Jrgen Sigvardsson, works a little differently as it takes three parameters. The Image Viewer application with a cursor

The left most part is the AND mask, the middle is the XOR mask, and the right most part is the actual icon or cursor as it will appear when drawn. The ShowIcon() and ShowCursor functions show the icon or cursor as a three part horizontal image. ShowGDIPlusBitmap(bmp) // take a peek at what is drawn. To watch a Gdiplus::Graphics object that you may be working on, create it with an Image, and watch that Image. The ShowBitmap(), ShowDC(), and ShowGDIPlusBitmap() functions will show the image "as-is". The possible return codes are explained below.

The API consists of the following macros: Some code that requires the image viewer tool You turn the viewer on by defining the ACTIVATE_VIEWER macro. Simply include the ImageViewer.h header file in the source file you have your drawing code in. All the neccessary files are contained in the Image Viewer utility download file.
