Detailed Description

Abstract base class for colormaps, which are transfer functions from a floating point value into RGBA values.

Member Function Documentation

void Wizt::Colormap::renew ( ) [inline]

If values in the colortable have been changed, call the renew() function to clear the local cache of the colormap.

Otherwise old values well be reused (in texture mode, in color table mode new values might be effective immediatly if the entries of getTable() have been modified).
