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.
