NAME

plscmap0a - Set color map0 colors by 8-bit RGB values and double alpha value.

SYNOPSIS

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

DESCRIPTION

Set color map0 colors using 8-bit RGB values (see the PLplot documentation) and floating point alpha value. This sets the entire color map -- only as many colors as specified will be allocated. This function is used in examples 30.

ARGUMENTS

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