Here are some answers.
1. No. Just Render->WriteImage instead of Image, for example
2. Yes, the general array importer can be used. Here's an example for
the W100N40.DEM file
file = W100N40.DEM
grid = 6001 x 4801
format = msb ieee
interleaving = record
majority = row
field = height
structure = scalar
type = short
dependency = connections
positions = regular, regular, 40., -0.00833333333333, -100.,
0.00833333333333
end
3. Reprojection should be done via coordinate warping. It is generic to any
geo-located data, not just
imagery. A discussion of the approach and examples are available at
http://www.research.ibm.com/dx/proceedings/cart/index.htm. The tools to
do what is discussed at
that site are available at:

4. In general, use Tube or Ribbon after Isosurface. You may wish to
Remove(,normals) afterwards. If you are
using OpenGL rendering, then Options(,"line width", n), where n is the
number of pixels thick.
Also, I do a bit of work with weather data and DX. Some of the
applications are not unlike what are outlined on your company's web site.

Subject: [opendx-users] Reproject images
I've just started to explore DX and have some questions.
I want to use DX to visualize meteorological data.
1. Does DX have to send an image to a screen in order
to export an image to a file when executing a script?
2. Is it straightforward to import gtopo30 DEM data
into DX?
3. Could someone tell me if there are modules/macros
that imports an image (with known dependencies)
and reprojects it to some new projection? I would like
to display an image overlayed by isolines of some field.
4. How do I control the line thickness from isosurface?
Thanks in advance,
Paul Skeie
