12 Plug-in Reference
The "coords" attribute contains [0..1] floating point coordinates where 0 is left or
top and 1 is right or bottom. The coordinates for the polygon points defining the
polygon shape need to be specified in the form:
x1, y1, x2, y2, x3, y3 ...
Theoretically you can use any number of coordinates (points), but keep in mind that
more coordinates and more polygons require more CPU power on the user's
system. Using very complex polygons with hundreds of coordinates will lead to poor
performance as the polygons will be drawn by FSI Viewer at runtime.
HotSpot Z-Order
When defining HotSpots that overlap each other, you have to keep the z-order of
the HotSpots in mind. The z- order of HotSpots is determined by the sequence in
which they are defined in the configuration file, from bottom to top.
As a rule of thumb you should define big Hot Spot areas first to ensure that smaller
Hot Spots are not completely hidden beneath.
