Les couleurs sont des actes de la lumière, ses actes et ses souffrances. Ainsi considéré, on peut attendre d’eux une explication de la lumière elle-même
Synopsis
avlcpt [-b rgb] [-f
rgb] [-h ] [-l adjust] [-n rgb]
[-o file] [-p precision] [-u adjust] [-v ] [-V ] [file]
DESCRIPTION
The avlcpt utility will extract a gradient from an ArcView Legend (avl) file and write it to the GMT (Generic Mapping Tools) cpt format. Note that not every avl file will contain a gradient, some just have patterns.
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,--backgroundrgb-
Set the background colour of the output.
--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. -f,--foregroundrgb-
Set the foreground colour of the output.
-h,--help-
Brief help.
-l,--loweradjust-
Decrease the lower limit on each segment by the specified amount.
-n,--nanrgb-
Set the NaN (no data) colour of the output.
-o,--outputfile-
Write the output to
file, rather thanstdout. -p,--precisionprecision-
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
-p10will round to the nearest 10 and so on. -u,--upperadjust-
Increase the upper limit on each segment by the specified amount.
-v,--verbose-
Verbose operation.
-V,--version-
Version information.
