NAME
cnice - make cheap colors
SYNOPSIS
cnice -q [-v] [-ca] [-f free] [-d distance] [colors]
cnice [-s] [-a] [-f free] [-d distance] -e command [args]
cnice -l [-a]
cnice -x [-m] [-a] [-f free] [-d distance] [files]
DESCRIPTION
cnice is an X application that queries the default colormap of the
default screen. It can be used to print out the map or examine the
color cells available for free use. cnice can also be used to pre-
parse argument of a command for color names and find the color that
takes the least resources. cnice is also able to parse X resource
files for color names and modify them. Optionally it can add 3d
shading color definition to the resource definitions for Motif.
OPTIONS
-q puts cnice into query mode. In this mode it expects color names.
The generated output in verbose mode:
tag: input_color -> output_color cellnumber distance
for each color. In non-verbose mode it is
s/input_color/output_color/g
for colors that need to be changed. Possible values for tag are:
allocated: color need to be allocated
exact: exact color can be shared
approximate: approximate color can be shared
far: far color can be shared
The number of free cells are summerized at the last line in
verbose mode. Used tells how many cells are not available for
any use because some application allocated the color cell for
private use (read-write). Shared tells how many cells can be
allocated read-only - sharing colors with other applications.
Free tells how many celss are available for private (read-write)
or shared (read-only) use.
-c is used with - q option. It keeps cnice running continuously.
Useful if you want to keep cells allocated.
-v turns off verbose mode.

-f free
sets up a threshold for the color allocation logic. If the number
of free entries in the colormap are equal to or more than this
number far colors get allocated. The default value is 20.
-d distance
sets up a distance for color chosing logic to determine which
colors should be considered far colors. The farest distance is
1000. This is the distance between black and white. The default
value is 70. Note that colors do not get allocated even if they
are far if there are less than threshold number of free cells
available.
-e command
This option should not be followed by any more options. cnice
executes the command by preparsing its command line arguments and
if any colors are found modify those to be allocatable/usable.
The rebuilt command line is passed to the program.
-s is used only with - e option. It makes cnice picky about colors.
Normally it accepts color names but with this option it will
ignore those that do not start with #.
-l lists all color cells and their availibility. The list format is:
cellno color free/used/shared
-x reads standard input and interpret the lines as Resource Database
values. cnice modifies the values that imply color names and
write the whole input with the edited values back to standard
output.
-m is used in conjunction with the - x option. It generates extra
output for shading colors for Motif. The extra resource name
generated from background are
foreground
armColor
topShadowColor
bottomShadowColor
