NAME

       plscmap1la - Set color map1 colors using a piece-wise linear relationship

SYNOPSIS

       plscmap1la(itype, npts, pos, coord1, coord2, coord3, coord4, rev)

DESCRIPTION

       This  is a version of plscmap1l(3plplot) that supports alpha transparency. It sets color map1 colors using a piece-wise linear relationship
       between position in the color map (from 0 to 1) and position in HLS or RGB color space (see the PLplot documentation) with alpha value (0.0
       - 1.0). It may be called at any time.

       This function is used in example 30.

ARGUMENTS

       itype (PLBOOL, input)
	      true: RGB, false: HLS.

       npts (PLINT, input)
	      number of control points

       pos (PLFLT *, input)
	      position for each control point (between 0.0 and 1.0, in ascending order)

       coord1 (PLFLT *, input)
	      first coordinate (H or R) for each control point

       coord2 (PLFLT *, input)
	      second coordinate (L or G) for each control point

       coord3 (PLFLT *, input)
	      third coordinate (S or B) for each control point

       coord4 (PLFLT *, input)
	      fourth coordinate, the alpha value for each control point

       rev (PLBOOL: *, input)
	      reverse flag for each control point. (rev[i] refers to the interpolation interval between the i and i + 1 control points).

NAME

       plshade -  Shade individual region on the basis of value

SYNOPSIS

       plshade(a,  nx,	ny,  defined,  xmin, xmax, ymin, ymax, shade_min, shade_max, sh_cmap, sh_color, sh_width, min_color, min_width, max_color,
       max_width, fill, rectangular, pltr, pltr_data)

DESCRIPTION

       Shade individual region on the basis of value.  Use plshades(3plplot) if you want to shade a number of  regions	using  continuous  colors.
       plshade(3plplot)  is  identical	to plshade1(3plplot) except for the type of the first parameter. See plshade1(3plplot) for further discus-
       sion.

       Redacted form:  General: plshade(a, defined, xmin,  xmax,  ymin,  ymax,	shade_min,  shade_max,	sh_cmap,  sh_color,  sh_width,	min_color,
       min_width, max_color, max_width, fill, rectangular, pltr, pltr_data) Perl/PDL: Not available?

       This function is used in example 15.

ARGUMENTS

       a (PLFLT **, input)

       nx (PLINT, input)

       ny (PLINT, input)

       defined (PLINT (*) (PLFLT, PLFLT), input)

       xmin (PLFLT, input)

       xmax (PLFLT, input)

       ymin (PLFLT, input)

       ymax (PLFLT, input)

       shade_min (PLFLT, input)

       shade_max (PLFLT, input)

       sh_cmap (PLINT, input)

       sh_color (PLFLT, input)

       sh_width (PLINT, input)

       min_color (PLINT, input)

       min_width (PLINT, input)

       max_color (PLINT, input)

       max_width (PLINT, input)

       fill (void (*) (PLINT, PLFLT *, PLFLT *), input)

       rectangular (PLBOOL, input)

       pltr (void (*) (PLFLT, PLFLT, PLFLT *, PLFLT *, PLPointer) , input)

       pltr_data (PLPointer, input)
