Colours are the deeds of light; its deeds and sufferings: thus considered we may expect from them some explanation respecting light itself.
Name
cptcont — create a continuous GMT colour palette table (cpt) file based on the colours of a non-continuous cpt file.
DESCRIPTION
The cptcont program converts a (possibly) discontinuous colour palette in the input to a continuous palette in the output. This is achieved by replacing the endpoints of segments at which a discontinuity occurs by their mean colour.
The program will read from stdin if a file is not specified as
the final argument, and write to stdout if the -o option is not specified.
OPTIONS
--backtrace-filepath-
Specify a file to which to write a formatted backtrace. The file will only be created if there is a backtrace created, typically when an error occurs.
--backtrace-formatformat-
Specify the
formatof the backtrace written to the files specified by--backtrace-file, one ofplain,xmlorjson. -h,--help-
Brief help.
-m,--midpoint-
Split each input segment into two output segments with the colour at the common point being the colour of the original segment. This gives a more faithful conversion of gradients with "corners", such as diverging gradients, albeit at the cost of larger files.
-o,--outputfile-
Write the output to
file, rather thanstdout. -p,--partialpercentage-
The endpoints are moved the specified
pecentagetowards the mean colour, so that a value of 100 (the default) moves the endpoints to the mean colour, 50 moves them half-way there, and so on.Negative values and values greater than 100 are permitted.
-v,--verbose-
Verbose operation.
-V,--version-
