You can create graphical hot spots using bitmaps. With a bitmap hot spot, the user clicks anywhere on the bitmap to activate the hot spot. Bitmap hot spots use the same display mechanism as regular pictures, so you can use your 16-color bitmaps and metafiles as hot spots.
Bitmap hot spots use the same positioning options as regular pictures (except for inline bitmaps, which don’t support text wrapping). For information on the alignment options for Help graphics, see Chapter 1
