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_WINDOW_COLORMAP_SIZE), that is if the color
index is transparent or outside the valid range of color indices.
