Using
a Bitmap as a Hot Spot
You can use
bitmaps as hot spots. This enables you to create graphics, such as icons or
buttons, and use them as jumps to particular topics or as hot spots for
macros. The following example uses the bitmap in the MYBUTTON.BMP file to
create a link. When the user clicks the bitmap, Windows Help jumps to the topic
identified by the context string topic15 :
{ \strike \{ bml mybutton.bmp\}}{ \v topic15}
You can also
divide a single bitmap into several hot spots and assign a different link or
macro to each hot spot. Such bitmaps, called segmented-graphics bitmaps, are
created by using Hotspot Editor. For example, if you have a bitmap of a dialog
box, you can assign links to each of the control windows in the dialog box,
enabling the user to click a control window and view information about it.
Segmented-graphics bitmaps already contain the context strings needed for the
links; only a bml or bmr statement is needed to insert the
bitmap. The \strike and \v statements must not be used.
