Colours are the deeds of light; its deeds and sufferings: thus considered we may expect from them some explanation respecting light itself.
cptcont — create a continuous GMT colour palette table (cpt) file based on the colours of a non-continuous cpt file.
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.
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.

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.
Write the output to

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.
