r.quant --help
r.quant [-tr] input=string[,string,...] [rules=name] [basemap=string]
[fprange=dmin,dmax] [range=min,max] [--help] [--verbose] [--quiet] [--ui]

--ui
Force launching GUI dialog

Parameters:
input=string[,string,...] [required]
Raster map(s) to be quantized

rules=name
Path to rules file ("-" to read from stdin)

basemap=string
Base map to take quant rules from

fprange=dmin,dmax
Floating point range: dmin,dmax

range=min,max
Integer range: min,max

DESCRIPTION


r.quant produces the quantization file for a floating-point map.

The map parameter defines the map for which the rules are to be created. If more than one
map is specified, then this implies that the floating-point range is the miniumum and
maximum of all the maps together, unless either basemap=map or fprange=min,max is
specified.

Quant rules
The quant rules have to be entered interactively.

If rules is specified, the input has the form:

value1:value2:cat1:[cat2]

where value1 and value2 are floating point values and cat1 cand cat2 are integers. If cat2
is missing, it is taken to be equal to cat1. All values can be "*" which means infinity.

NOTE


It is an error for both basemap and fprange to be specified.
