NAME

       plscmap1 - Set opaque RGB cmap1 colors values

SYNOPSIS

       plscmap1(r, g, b, ncol1)

DESCRIPTION

       Set  opaque  cmap1  colors  (see  the PLplot documentation) using RGB vector values.  This
       function also sets the number of cmap1 colors.  N.B. Continuous cmap1 colors  are  indexed
       with a floating-point index in the range from 0.0-1.0 which is linearly transformed (e.g.,
       by plcol1(3plplot)) to an integer index of these RGB  vectors  in  the  range  from  0  to
       ncol1-1.   So  in  order  for  this  continuous  color  model  to work properly, it is the
       responsibility of the user of plscmap1(3plplot) to  insure  that  these  RGB  vectors  are
       continuous functions of their integer indices.

       Redacted form: plscmap1(r, g, b)

       This function is used in example 31.

ARGUMENTS

       r (PLINT_VECTOR(3plplot), input)
              A  vector  that  represents (using unsigned 8-bit integers in the range from 0-255)
              the degree of red in the color as a continuous function of the integer index of the
              vector.

       g (PLINT_VECTOR(3plplot), input)
              A  vector  that  represents (using unsigned 8-bit integers in the range from 0-255)
              the degree of green in the color as a continuous function of the integer  index  of
              the vector.

       b (PLINT_VECTOR(3plplot), input)
              A  vector  that  represents (using unsigned 8-bit integers in the range from 0-255)
              the degree of blue in the color as a continuous function of the  integer  index  of
              the vector.

       ncol1 (PLINT(3plplot), input)
              Number of items in the r, g, and b vectors.
