NAME
     cmap_compact -  colormap  configuration  utility  to  reduce
     colormap flashing.

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  screens;  it
     applies only to color screens.

     For more information about the general problem  of  colormap
     flashing  and  instructions  for using cmap_compact to solve
     the problem, refer to the OpenWindows documentation.

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  Sta-
     ticColor  default  colormap.   Note  also that the server is
     grabbed during the save.

     init Reads the colors which have been saved  in  ~/.owcolors
          and  allocates 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 color-
     map 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  initial-
     ized 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  invo-
     cation.

     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  exam-
     ple,  might  occur  if  the the default visual 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 colormap.
     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.  Con-
          tains  a  list of saved, read-only workspace colors for
          all screens.

BUGS
     Currently does not support using the same  ~/.owcolors  file
     for different machine architectures.
