NAME
       plimagefr - Plot a 2D matrix using color map1

SYNOPSIS
       plimagefr(idata, nx, ny, xmin, xmax, ymin, ymax, zmin, zmax, valuemin, valuemax, pltr, pltr_data)

DESCRIPTION
       Plot a 2D matrix using color map1.

       Redacted form:  General: plimagefr(idata, xmin, xmax, ymin, ymax, zmin, zmax, valuemin, valuemax, pltr, pltr_data)

       This function is used in example 20.

ARGUMENTS
       idata (PLFLT**, input)
	      A 2D array of values (intensities) to plot.  Should have dimensions idata[nx][ny].

       nx, ny (PLINT, input)
	      Dimensions of idata

       xmin, xmax, ymin, ymax (PLFLT, input)
	      Stretch  image  data  to	these  Plot coordinates.  idata[0][0] corresponds to (xmin, ymin) and idata[nx - 1][ny - 1] corresponds to
	      (xmax, ymax).

       zmin, zmax (PLFLT, input)
	      Only data between zmin and zmax (inclusive) will be plotted.

       valuemin, valuemax (PLFLT, input)
	      The minimum and maximum data values to use for value to color mappings.  A datum equal to or less than valuemin will be plotted with
	      color  0.0,  while a datum equal to or greater than valuemax will be plotted with color 1.0.  Data between valuemin and valuemax map
	      linearly to colors between 0.0 and 1.0.

       pltr (void (*) (PLFLT, PLFLT, PLFLT *, PLFLT *, PLPointer) , input)
	      Pointer to function that defines a transformation between the data in the array idata and world coordinates.  An input coordinate of
	      (0,  0) corresponds to the "top-left" corner of idata while (nx, ny) corresponds to the "bottom-right" corner of idata.  Some trans-
	      formation functions are provided in the PLplot library: pltr0(3plplot) for identity mapping, and pltr1(3plplot)  and  pltr2(3plplot)
	      for  arbitrary mappings respectively defined by one- and two-dimensional arrays.	In addition, user-supplied routines for the trans-
	      formation can be used as well.  Examples of all of these approaches are given in the PLplot documentation.  The transformation func-
	      tion should have the form given by any of pltr0(3plplot), pltr1(3plplot), or pltr2(3plplot).

       pltr_data (PLPointer, input)
	      Extra  parameter	to help pass information to pltr0(3plplot), pltr1(3plplot), pltr2(3plplot), or whatever routine is externally sup-
	      plied.
