Hotspots are active, clickable areas in graphics. Hotspot data is stored separately from the graphics, which makes it possible to add hotspots to all graphics types, not just special hotspot graphics. All the link types supported in the editor are also supported in hotspots (topic links, Internet links, file links and script links).
Since the link types are identical to those used in normal topics their settings are only described briefly here. See Links, Anchors, Macros, Scripts and HTML for more information on hyperlinks.
Hotspots in graphics are only supported in electronic output formats (HTML Help, Windows eWriter Help, Visual Studio Help and PDF with hyperlinks activated). ePUB eBook readers do not support hotspots.
