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


       _m_a_p_=_n_a_m_e    The	map for which the rules be 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.

	_b_a_s_e_m_a_p_=_m_a_p  The quant rules of this map set the quantization.

	_f_p_r_a_n_g_e_=_m_i_n_,_m_a_x   This sets the floating-point range for the quantiza-
       tion.

	    _-_t _f_l_a_g   Truncate floating point data

	    _-_r _f_l_a_g  Round floating point data

	_r_a_n_g_e_=_m_i_n_,_m_a_x	This sets the integer range for the quantization. Oth-
       erwise a default of 1-255 is used.

       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.



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