Hi Hazen: Much thanks for this effort which is going to make colour management much easier for PLplot. Currently plspal0 and plspal0 simply fopen the specified file with no checks on whether it exists. One obvious way to deal with that issue is to use the same function (plLibOpenPdfstrm) we use for opening map files and also our traditional Hershey font files. plLibOpenPdfstrm currently tries a large number of standard locations (including the current directory) to find the file specified. If you go that route, then everything will magically work without having to include the path of the colour palette file names that are specified on the command line. Of course, to answer Hez's question, you would have to place our "official" palette files in the data directory in the source tree and install them in DATA_DIR (which currently corresponds to $prefix/share/plplot5.9.4) in the install tree. But the current directory search by plLibOpenPdfstrm should work well for the casual user who is just trying out some palette files of his own. Alan __________________________ Alan W.
