avlcpt: convert ArcView Legend gradients to GMT colour palette tables
NAME
avlcpt - convert ArcView Legend gradients to GMT colour palette tables
SYNOPSIS
-
avlcpt [-b
rgb] [-f rgb] [-h] [-l adjust] [-n rgb] [-o file] [-p precision] [-u adjust] [-v] [-V] [file]
DESCRIPTION
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
In the following, all rgb specifications should be of the form red/green/blue where the colour components are integers in the range 0 to 255.
-b, --background rgb
- Set the background colour of the output.
-f, --foreground rgb
- Set the foreground colour of the output.
-h, --help
- Brief help.
-l, --lower adjust
- Decrease the lower limit on each segment by the specified amount.
-n, --nan rgb
- Set the NaN (no data) colour of the output.
-o, --output file
- Write the output to file, rather than stdout.
-p, --precision precision
- Specify rounding. ArcView legends have a rather interesting approach to height specification whereby colour ranges might be 0-49, 50-99, and so on. The cpt format requires that the end of one segment be at the same as the start of the next, so some rounding of the input will usually be required. The precision is specified directly rather than by number of digits, so that -p10 will round to the nearest 10 and so on.
-u, --upper adjust
- Increase the upper limit on each segment by the specified amount.
-v, --verbose
- Verbose operation.
-V, --version
- Version information.
