glutCopyColormap(3GLUT) 					       GLUT						   glutCopyColormap(3GLUT)

NAME

       glutCopyColormap - copies the logical colormap for the layer in use from a specified window to the current window.

SYNTAX

       void glutCopyColormap(int win);

ARGUMENTS

       win	 The identifier of the window to copy the logical colormap from.

DESCRIPTION

       glutCopyColormap  copies (lazily if possible to promote sharing) the logical colormap from a specified window to the current window's layer
       in use. The copy will be from the normal plane to the normal plane; or from the overlay to the overlay  (never  across  different  layers).
       Once a colormap has been copied, avoid setting cells in the colormap with glutSetColor since that will force an actual copy of the colormap
       if it was previously copied by reference. glutCopyColormap should only be called when both the current window and the win window are  color
       index windows.

EXAMPLE

       Here is an example of how to create two color index GLUT windows with their colormaps loaded identically and so that the windows are likely
       to share the same colormap:

	 int win1, win2;

	 glutInitDisplayMode(GLUT_INDEX);
	 win1 = glutCreateWindow("first color index win");
	 glutSetColor(0, 0.0, 0.0, 0.0);  /* black */
	 glutSetColor(1, 0.5, 0.5, 0.5);  /* gray */
	 glutSetColor(2, 1.0, 1.0, 1.0);  /* black */
	 glutSetColor(3, 1.0, 0.0, 0.0);  /* red */
	 win2 = glutCreateWindow("second color index win");
	 glutCopyColormap(win1);
