CPTCONT(1) User commands CPTCONT(1) NAME cptcont - create a continuous GMT colour palette table (cpt) file based on the colours of a non-continuous cpt file. SYNOPSIS cptcont [-h] [-m] [-o file] [-p percent] [-v] [-V] [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-file path 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-format format Specify the format of the backtrace written to the files specified by --backtrace-file, one of plain, xml or json. -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, --output file Write the output to file, rather than stdout. -p, --partial percentage The endpoints are moved the specified pecentage towards 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 Version information. EXAMPLE Create an almost-continuous table: cptcont -v -p 66 -o new.cpt old.cpt AUTHOR J.J. Green SEE ALSO GMT(1). CPTUTILS 22 Feb 2017 CPTCONT(1)
