show palette palette <n> savergb

[Petr M. <mi...@ph...>]

Currently gnuplot can print colour palette table on screen by 'show palette
palette <n>'. I made a patch which can save it to a file, just 3 columns of
r,g,b, to be easily plotted by gnuplot as colour profiles. The syntax
proposed is below. Does somebody propose any other addition? (E.g. how to
save lut files?)


show palette palette <n> {savergb {<scale> {int}} 'filename'}

`show palette palette <n>` shows RGB triplets for the current settings and a
palette having <n> discrete colors. This table can be saved into a
`filename` (accepting also '-' and '|pipe_command'), optionally scaled by
'<scale>' and rounded to integer values.
