Thanks, Mario, for reminding me of eps_color.
I have been using just terminal=eps for all other
draw2d plots, with good color output, so never bothered
Using eps_color with the image function did restore color, but
has an additional editing behavior. I had sampled the expression
x*y at 25 points, with x in (0,1), y in (0,1), to form the matrix
passed to image(...).
This produces a very discrete looking "density plot" with both the
gnuplot console window and also the terminal=jpg case.
But terminal=eps_color appears to smooth its input, giving a very
smooth density plot with none of the discreteness which should have
I basically gave up on both eps and eps_color, and used cygwin's convert
function (convert case.jpg case.eps ) to get an accurate eps file. This was
not a perfect solution, since there is a mysterious dotted line along the
Anyway, thanks for the suggestion. I am making good progress on my "qdraw"
graphics interface to draw2d and am trying to resist the temptation to
and more features(!).
