Name

cptpg — convert GMT colour palette tables (cpt) to PostGIS colour-maps.

Synopsis

cptpg [-h ] [-o file] [-p ] [-v ] [-V ] [file]

DESCRIPTION

The cptpg utility converts the colour palette table (cpt) files used by GMT(1) to the colour-maps used by PostGIS, in particular those for the ST_ColorMap function. It should also be possible to use the maps in the GDAL program gdaldem, the GRASS r.colors utility and in ESRI products which call for a HDR color table.

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.

-o, --output file

Write the output to file, rather than stdout.

-p, --percentage

Convert (z) values to percentages.

-v, --verbose

Verbose operation.

-V, --version

Version information.
