plgcol0 (icol0,
 r,
 g,
 b);
 

Returns 8-bit RGB values (0-255) for given color from cmap0 (see the section called “Color Map0”). Values are negative if an invalid color id is given.

icol0 (PLINT, input)

Index of desired cmap0 color.

r (PLINT_NC_SCALAR, output)

Returned value of the 8-bit red value.

g (PLINT_NC_SCALAR, output)

Returned value of the 8-bit green value.

b (PLINT_NC_SCALAR, output)

Returned value of the 8-bit blue value.
