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 GLUT_RED, GLUT_GREEN, or GLUT_BLUE.
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(GLUT_WIN-
DOW_COLORMAP_SIZE), that is if the color index is transparent or out-
side the valid range of color indices.
