Dear NCAR Folks,
This may be a problem with the translator, but I'm not sure.
When generating a rectangular image but I do not want any kind
of smoothing, instead of contouring the image I display the
data using a cell array call (GCA). An example displaying a
360x180 grid (igrd(360,180)) is below.
call gca(x1,y1,x2,y2,360,180,1,1,360,180,igrd)
This looks like it works fine when I examine my results using
ctrans (i.e. ctrans gmeta), however then I create a PostScript
file from this meta file (ctrans -d ps.color gmeta > foo) for
high quality print-outs. The problem. The resulting
PostScript file is very very large, to the point where we can
not work with them easily, if at all. If you generate more than
one such rectangular image on a page - forget it. This has
prevented some people here from using NCAR Graphics for their
images, which is disappointing because it is high quality.
First question I guess is, are cell arrays what I should be
using for this ?? I have reviewed the book several times and
cell arrays seems to be just what I need. I want to display
a grid of data, but I want to see each grid cell, I do not
want the data smoothed. Also, displaying the 'gmeta' file
is pretty quick. So I believe I am using the correct NCAR
feature. If so then am I doing something wrong wrt the
translation into PostScript ?? or is that simply the way
it works with cell arrays ?? Perhaps there is a new and
improved translator that has addressed this problem ?? Or
am I the only one in the universe who has this problem ??
I am currently using ctrans.3.2.1. Anybody have any ideas ??
Thanx
