The grayscale ramp on Palm displays is hardly linear, but the
conversion ramp we use for images is indeed linear. This means that
there are ranges of color which get lumped together somewhat badly.
To make things worse, the particular ramp seems to depend on the kind
of screen you happen to get in the particular kind of Palm you get.
Someone needs to write a grayscale calibration tool which in which
you'd fiddle with a calibration panel to get things looking right,
then upload a DB to the PC side of things, where it would be converted
into a custom quantification map for use by the Plucker distiller.
Lacking that, you can fiddle with the default quantification if you
are using netpbm as your image converter. It comes with a standard
colormap called "palmgray4.map", which gets stuck in the netpbm "lib"
subdirectory. If you change the value of "palm4bit_graymap_file" in
your ~/.pluckerrc file, you can then create a clone of the
"palmgray4.map" file somewhere and experiment with the specific color
'buckets' till you get something that looks better on the Palm.
If you come up with something you like better, please send a note so
that we can adjust things (as an option).
