plspal1: Set the palette for cmap1 using the specified cmap1*.pal format file 

DESCRIPTION:

    This function is used in example 16. 

SYNOPSIS:

plspal1(filename, interpolate)

ARGUMENTS:

    filename (const char *, input) :    The name of the cmap1*.pal file,
    or an empty string to specify the default cmap1.pal file. 

    interpolate (PLBOOL, input) :    If this parameter is true, the
    columns containing the intensity index, r, g, b, alpha and
    alt_hue_path in the cmap1*.pal file are used to set the cmap1
    palette with a call to plscmap1la. (The cmap1*.pal header contains
    a flag which controls whether the r, g, b data sent to plscmap1la
    are interpreted as HLS or RGB.) If this parameter is false, the
    intensity index and alt_hue_path columns are ignored and the r, g,
    b (interpreted as RGB), and alpha columns of the cmap1*.pal file
    are used instead to set the cmap1 palette directly with a call to
    plscmap1a.
