NAME
       cmap_compact - colormap configuration utility to reduce colormap flash-
       ing.

SYNOPSIS
       cmap_compact [ op ] [ -display dpyname ]

DESCRIPTION
       cmap_compact is a utility which allows certain colors to be  designated
       as  special  and to be promoted to the high end of the default colormap
       (toward pixel 255).  This reduces colormap flashing in many situations.

       This technique has no effect for monochrome or full color  screens;  it
       applies only to PseudoColor screens.

OPTIONS
       -display dpyname
              Indicates the X11 display to use.  ':0' is the default.

       op can be one of the following operations:

       save   Records the RGB color values of all shareable (read-only) colors
              in the default colormap for each active screen and  saves  these
              values on the file ~/.owcolors.

       The  black  and  white  pixels  (typically  at  pixels 254 and 255) are
       ignored during the save.

       Note that all colors are ignored for screens with a StaticColor default
       colormap.  Note also that the server is grabbed during the save.

       init   Reads  the colors which have been saved in ~/.owcolors and allo-
              cates them as read-only colors at the high-end  of  the  default
              colormap.   The  color  allocations for those applications which
              use these colors will be derived from  these  high  colors.   If
              there  is no ~/.owcolors file, nothing happens and no message is
              printed out.

       The colors are allocated in reverse order of the order  in  which  they
       were  saved.   Thus,  the  lowest  pixel  in  the colormap at save time
       becomes the highest pixel at initialization time.

       This operation is typically invoked from ~/.xinitrc prior  to  starting
       the color applications.

       This  operation  creates  on  the root window of each screen a property
       named XA_COMPACTED_COLORS_COUNT of type XA_INTEGER.  The value of  this
       property  specifies  the  number of initialized colors for that screen.
       Note: this value also includes the black and white pixels.

       An X11 close down mode of RetainPermanent is set  so  that  the  colors
       this  program  allocates  will  stay  around  after cmap_compact exits.
       These colors may be freed by  calling  cmap_compact dealloc  .   Before
       this program allocates its colors, it frees any colors left over from a
       previous invocation.

       If there are more saved colors than can fit in the default colormap, as
       many  colors as will fit are allocated and a warning message is printed
       out.   This situation, for example, might occur if the the default vis-
       ual  were  switched  from an 8-bit to a 4-bit visual without discarding
       saved colors.

       Note: no allocations occur for screens with a StaticColor default  col-
       ormap.
       Note: The server is grabbed during the initialization.

       discard
              This operation removes the file ~/.owcolors.

       dealloc
              This  operation  frees colors allocated by a previous invocation
              of cmap_compact init.

       show   This operation prints out the RGB values of the saved colors for
              each screen.

FILES
       ~/.owcolors
              The  file  which  is generated by cmap_compact save.  Contains a
              list of saved, read-only workspace colors for all screens.
