C++ API

: spinmap ()
: spinmap (t)
: spinmap (t, inc)
: spinmap ("inf")

Cycle the colormap for t seconds with a color increment of inc.

Both parameters are optional. The default cycle time is 5 seconds and the default increment is 2. If the option "inf" is given then cycle continuously until Control-C is pressed.

When rotating, the original color 1 becomes color 2, color 2 becomes color 3, etc. A positive or negative increment is allowed and a higher value of inc will cause faster cycling through the colormap.

See also: colormap.
