onemap(3G)

NAME
     onemap - organizes the color map as one large map

FORTRAN 77 SPECIFICATION
     subroutine onemap

PARAMETERS
     none

DESCRIPTION
     onemap organizes the color map of the currently active framebuffer as a
     single map.  Because single map mode is the default value for all GL
     framebuffers, it can be called in any of the framebuffer drawmodes
     (NORMAL, PUPDRA, OVERDR, and UNDERD).  To return the normal framebuffer
     to single map mode, however, you must call onemap while in drawmode
     NORMAL.

     The single color map allocated to a framebuffer in onemap mode has as
     many entries as are supported by the bitplanes in that framebuffer.  The
     normal framebuffer has up to 12 bitplanes, and therefore up to 4096 color
     map entries.  Call getpla after setting draw mode to the desired
     framebuffer to determine the color map size.  getgde can also be called
     at any time to determine the size of the color map of any framebuffer.

     onemap does not take effect until gconfi is called.  When called, gconfi
     executes onemap requests pending for all draw modes, regardless of the
     current draw mode.

     A framebuffer's color map is used to display pixels only if the
     framebuffer is in color map mode (see cmode).

NOTES
     This routine is available only in immediate mode.

     On Iris Entry, Indy, XL, XS, XS24, XZ, Elan, Extreme, and IRIS-4D
     RealityEngine systems multim is not supported so onemap is always in
     effect for color map mode.
