PLSCOL0A(3plplot) PLplot API PLSCOL0A(3plplot)
NAME
plscol0a - Set a given color from color map0 by 8 bit RGB value and double alpha value.
SYNOPSIS
plscol0a(icol0, r, g, b, a)
DESCRIPTION
Set a given color by 8-bit RGB value and double alpha value for color map0 (see the PLplot documentation). Overwrites the previous color
value for the given index and, thus, does not result in any additional allocation of space for colors.
This function is used in example 30.
ARGUMENTS
icol0 (PLINT, input)
Color index. Must be less than the maximum number of colors (which is set by default, by plscmap0n(3plplot), or even by
plscmap0(3plplot)).
r (PLINT, input)
Unsigned 8-bit integer (0-255) representing the degree of red in the color.
g (PLINT, input)
Unsigned 8-bit integer (0-255) representing the degree of green in the color.
b (PLINT, input)
Unsigned 8-bit integer (0-255) representing the degree of blue in the color.
a (PLFLT, input)
double value (0.0-1.0) representing the alpha value of the color.
