Gmt2kml and cpt and circle

Q&A
1

I dont understand what is wrong if I want to use the option -Ccolor.cpt with
gmt gmt2kml myfile.dat -Fs -Ccolor.cpt > myfile.kml

gmt2kml [ERROR]: Cannot use continuous color palette. Here the idea is to associate different colours to each point depending on the amplitude value we can find on the 3rd column.

Any comment?

gmt2kml is a filter so input may come from files or stdin. We need to build the KML styles up front for the various colors. If you use a continuous CPT then there is an infinite number of colors (since we have not read any data yet). Just decimate your CPT by using a small increment and you get a finite number of colors.
