39 Raster map(s) to be quantized
40
41 rules=name
42 Path to rules file ("-" to read from stdin)
43
44 basemap=string
45 Base map to take quant rules from

48 Floating point range: dmin,dmax

50 range=min,max
51 Integer range: min,max
52
54 r.quant produces the quantization file for a floating-point map.
55
56 The map parameter defines the map for which the rules are to be cre‐
57 ated. If more than one map is specified, then this implies that the
58 floating-point range is the minimum and maximum of all the maps to‐
59 gether, unless either basemap=map or fprange=min,max is specified.
60
61 Quant rules
62 The quant rules have to be entered interactively.
63
64 If rules is specified, the input has the form:
65
66 value1:value2:cat1:[cat2]
67
68 where value1 and value2 are floating point values and cat1 cand cat2
69 are integers. If cat2 is missing, it is taken to be equal to cat1. All
70 values can be "*" which means infinity.
71
73 It is an error for both basemap and fprange to be specified.
