The image properties dialog ShowGraphic() API function The Properties dialog also shows the image size in pixels, the bit-depth of the image, and the source file and line number where the Show* macro was called. It will be seen in the child frames status bar and can also be seen in the properties dialog. The second version of the functions take a LPCTSTR pointer to a descriptive text that can be accessed later from the Image Viewer application when viewing the image. Image Viewer showing an HRGN region by inverting the colours of a bitmap 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.
