Hello,
First of all thank you for very interesting peace of code.
Unfortunately, your response is only indirectly related to the problem
mentioned above.
The problem is not just to export high-quality EPS-file. I also need
to possibly reduce its size prior to export by removing redundant
points. I have 3D-line plot which contains more than 20000 point and
exporting in huge eps-file. The line is smooth but have very
sophisticated behavior and I really need so much points for having the
plot to be of sufficient quality. But it is apparent that in 2D-
version of this 3D-line I do not need more so much point because some
(thousands!) of them are projected in a (approximately) one point.
So, having internal Mathematica's 2D-representation of this line I
could optimize number of point and produce a plot of the same quality
but having a size of 10-50 times less. It is not difficult to get a
projection of the line.
But what really is the problem - is to get a 2D-projection of axes
with ticks, labels and gridlines in the coordinate system of the line.
