Hi.
I'm new here. I have to evaluate IDL to see if some of the features
incorperated in one of our WINDOWS apps can be done with IDL under UNIX.
Specifically, with the current app, you can load in a satellite data image
and, using a 'transparent' bitmap, draw a coastline over top of the image
which you can then slide around, using the mouse, to render correction fo
satellite pitch, roll, time etc.
The image is drawn pixel by pixel, and the coastline is drawn with
polygons, using lat/lons translated into the images data pixel
coordinated, then retranslated into window coordinates.
Can anyone tell me if it can be done, and if so, using what
functions/parameters/keywords?
Thanks in advance
James
