I sent the following yesterday, but since it was my first request to the
list, I got an autoreply. It never showed up in my digest of the list, and I
haven't seen a response. It's in the archives, but I am thinking that
archiving/autoreply was all that happened (no actual posting.)
Anyway, I am looking hard at PIL, and a little at PyGame. Still looking for
suggestions, though.
::::::::::::::::
I work for a Civil Engineering organization. I need to give our users a
means to generate geographic coordinates for our projects and structures.
I plan to do this by making a viewer which will accept a graphic file (png
or jpg) and two points (pixels) in that image for which geographic
coordinates are given. Users can then click on the image where appropriate to
generate a list of geographic points of interest for their work. The list will
be saveable as an xml file or a shp file (a widely used geographic binary
format.) In addition, other programs that I write will use the viewer as a
dialog box: will call the viewer directly and get the points from it, just
like a color picker dialog.
What I am looking for: thoughts on which Python modules are most
appropriate and generally applicable for this. PIL? Piddle? PyGIS? some of
Hobu's modules? I believe I can write the glue-code, but I don't want to
reinvent the wheel if there are existing modules that do
almost (or even better, exactly) what I need.
I work on WinXp, Linux, and WindowsCE. WindowsCE has a fairly
plain-vanilla Python build, so it's better if I stick to the core modules as far
as possible.
