Cannot compile a certain file 1570 1
Started by Deleted User
Hi,
I debugged a code I have for creating a nice, but simple, GUI but now when I try to compile it, it just hangs. According to the debug watch window, the interpreter is running but there is nothing happening in the console window and all attempts to enter more commands are just queued up. What have I done And apart from exiting IDL, is there a way to stop the interpreter and regain control
I am running 8.1 on Mac OS 10.6.8
Thanks

RedHat linux and file_move procedure issues 1496 1
Started by Deleted User
I'm running IDL 8.1 on Red Hat Enterprise Linux WS release 4 (Nahant Update 5) and I'm comming across this funny issue. When using file_move like below:
file_move, zip_file, outfile, /allow_same, /overwrite
I'm getting this prompt in the console:
mv: overwrite `/work/srco/decision/output/local_archive/RTWP/IO_DIST_BOX.zip'
The same program is working fine on Red Hat Enterprise Linux Client release 5.5 (Tikanga)
Can someone tell me what versions of Linux IDL 8.1 supports

Hi all !,
When I try to export xvolume figure with export vmrl bar menu, If isosurface off option is enabled then I obtain a small size file and I can't view it with a vmrl viewer (It only draws the axis into a empty figure).
If isosurface opaque option is enabled then I can view this isosurface with a vmrl viewer but it only shows a grayscale figure without colours.
I'm very interested to export the full volume figure to vrml. Exist a bug with the VMRL export option

Start IDL only when license is available 1306 0
Started by Deleted User
Hi everybody,
we would like to make sure that an IDL license is available when starting it. Now the command line option that seems to do this (-queue) works as expected when no license is available (thus the demo mode is not started, but instead one is listed as waiting for license). It does however never comes back, even when a license is later available (I interrupted the shell after > 1hour). We run Suse Linux 11.1, IDL versions are from 6.4 to 8.x available.
Any ideas

Automatically orthorectifying a cell 1316 1
Started by Deleted User
Hello,
In our company we are orthorectifying a very large amount of images. For now we just use the GUI of ENVI (Map > Orthorectification) to do the job, but it is very time consuming. I am trying to automate the process, and it seemed clear that IDL was the right tool.
However, I have not been able to find an API to call ENVI's orthorectification module from IDL. Is it possible in the first place And if it is not possible, does anybody know a way to automate this process
Thanks...

Layer Stacking 1723 4
Started by Deleted User
I'm currently Layer Stacking the 8 bands of WorldView 2 down to three. The WorldView 2 images already come layer stacked into 8 bands, but I'm only interested in three. I'm a beginner at IDL, but I've wrote a script in the past to layer stack individual bands (from separate files) into one multi file. I was wondering if there is a script to just layer stack and separate the three bands
Thanks

So I added at the beginning of my procedure the following:

IDLgrPolygon 1741 0

I would like to know if it is possible to create multiple polygons using object graphics and then selectively remove one or more polygons. Polygons can be overlapped or embedded within another polygon. Also the polygons will have to be transparent with a highlighted edge. Any help with example would be helpful.
