DESCRIPTION

47       r.quant produces the quantization file for a floating-point map.
48
49       The map parameter defines the map for which the rules be to be created.
50       If more than one map is specified, then this implies that the floating-
51       point range is the miniumum and  maximum  of  all  the  maps  together,
52       unless either basemap=map or fprange=min,max is specified.
53

Quant rules

55       The quant rules have to be entered interactively.
56
57       If rules is specified, the input has the form:
58
59       value1:value2:cat1:[cat2]
60
61       where  value1  and  value2 are floating point values and cat1 cand cat2
62       are integers. If cat2 is missing, it is taken to be equal to cat1.  All
63       values can be "*" which means infinity.
64

NOTE

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