plscmap0a — Set cmap0 colors by 8-bit RGB values and double alpha transparency value

Synopsis

plscmap0a(r, g, b, alpha, ncol0)

Description

Set cmap0 colors using 8-bit RGB values (see the PLplot documentation) and floating point alpha transparency value. This sets the entire color map -- only as many colors as specified will be allocated.

Redacted form: plscmap0a(r, g, b, alpha)

This function is used in examples 30.

Arguments

r (const PLINT *, input)
Pointer to array with set of unsigned 8-bit integers (0-255) representing the degree of red in the color.
g (const PLINT *, input)
Pointer to array with set of unsigned 8-bit integers (0-255) representing the degree of green in the color.
b (const PLINT *, input)
Pointer to array with set of unsigned 8-bit integers (0-255) representing the degree of blue in the color.
alpha (const PLFLT *, input)
Pointer to array with set of PLFLT values (0.0 - 1.0) representing the alpha transparency of the color.
ncol0 (PLINT, input)
Number of items in the r, g, b, and alpha arrays.
