plspal1 (3plplot)

plspal1(filename, interpolate)

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

Redacted form: plspal1(filename, interpolate)

This function is used in example 16.

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(3plplot). (The cmap1*.pal header contains a flag which controls whether the r, g, b data sent to plscmap1la(3plplot) 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(3plplot).
