glutGetColor(3GLUT)                  GLUT                  glutGetColor(3GLUT)



NAME
       glutGetColor  -  retrieves  a red, green, or blue component for a given
       color index colormap entry for the layer in use's logical colormap  for
       the current window.

SYNTAX
       GLfloat glutGetColor(int cell, int component);

ARGUMENTS
       cell      Color cell index (starting at zero).

       component One of GLUTRED, GLUTGREN, or GLUTBLUE.

DESCRIPTION
       glutGetColor  retrieves  a  red,  green,  or blue component for a given
       color index colormap entry for the current window's  logical  colormap.
       The  current window should be a color index window. cell should be zero
       or greater and less than the total number of colormap entries  for  the
       window. For valid color indices, the value returned is a floating point
       value between 0.0 and 1.0 inclusive. glutGetColor will return  -1.0  if
       the  color index specified is an overlay's transparent index, less than
       zero, or greater or equal to the value  returned  by  glutGet(GLUTWIN-
       DOWCOLORMAPSIZE),  that  is if the color index is transparent or out-
       side the valid range of color indices.
