Hi,
I am new to widgets. I am entering floating point numbers in my text widget, but once they have passed through event handling they are returned as integer values. Does this sound like something familiar to you that I may be missing

Segmentation fault IDL 6.3 on Linux Debian Etch 1788 4
Started by Deleted User
Hi.
We are evaluating IDL 6.3 on Linux Debian Etch and have run into a segmentation fault error each time a graphic device is started (e.g. IDL> help,/device ).
In a previous thread (2165: Segmentation fault: IDL 6.3 on Debian SID: Hm Li), the same problem was detected on Debian Sid and a workaround was offered. We have tried reinstalling the X Windows packages as suggested, but with no success (it failed even after a fresh linux installation).
Any help would be really appreciated.

Intensity Profile - Spectroscopy from Image 1334 0
Started by Deleted User
Hi,
I have to do some analysis and was hoping someone who has done something similar might help!
I have some spectroscopic data, and my image from the FPA is the spread out light. I basically want to analyze a portion of this, and obtain intensity vs. pixels (i.e. corresponding to wavelength) to get the spectrum. I can open my image both in IDL and IImage and did do the histogram profile in IImage, but need something more for pixel by pixel.
Any help would be appreciated!
Thanks,
Radha

Stop responding ENVI/IDL 2274 0
Started by Deleted User
I have a strange problem in ENVI/IDL.
Has anyone encountered the situation where after they compile their project files, IDL stops responding and the processor runs at 100
If I close all the file windows within IDL, the project compiles fine and I can run my project; but then if I open any of the files in my project, IDL stops responding once again.
Thank you.

question about exiting 1336 1
Started by Deleted User
This question has to do with a project that I inherited from another worker that is no longer here (so I am still learning about the code). In the main Window of the application, in the upper right hand corner are the standard Minimize, Maximize, and Exit (X) buttons. Is there a way to take control of the Exit button so that when a user clicks on it I control what happens to the program Thank you.

Converting TIFF to ENVI format 4065 1
Started by Deleted User
Hi,
I have some image files that are .tif files. They are 320x241 the 241st being the header. I need to convert these file images into raw binary files (columns and rows of 1 and 0s) and the accompanying header to be able to work with them. Is there any easy way of doing this in IDL - (I do not have ENVI)
Thank You!!

700 aerial photographs 1467 1
Started by Deleted User
Hi there, new on the forum and very new to IDL. Glad to be here.
I have 700 aerial photographs which are in .tiff format. When I open one in ENVI, a dialogue box opens up and asks me to specify the projection and datum. This is United Kingdom, OS of Great Britain 36' for each one. Once I select this the image displays and is georefferenced. I was wondering if i could write an IDL script which would enable me to batch process each image so i don't need to specify the projection info each time...

cropping fits images 1995 0
Started by Deleted User
The imcopy tool in iraf does an excellent job cropping images. It retains the wcs information and
even keeps the original pixel indices. I have not been able to reproduce this in IDL.
I can do a crop and resave it with the header but then I have to change the crpix, cdelt and naxis values. I am not
even sure that this gives and accurate wcs and it assumes you have matched up a pixel location with its coordinates. I tried using modfits but this doesn't change the size of the image.

Re-sampling radar data to a lat/lon grid 1316 0
Started by Deleted User
Hi,
I am wondering about the best method for converting some previously fixed-distance (2km) gridded radar data to a more coarse, earth-fixed grid. The data consists of a 151 x 151 pixel array of rain estimates. I know the center of each 2 km pixel with respect to lat/lon and the middle pixel (75,75) is the location of the radar.
I want to choose, say a 0.25 or 0.5 degree grid centered over the data and resample the data to that grid. Note that I have missing data near the center of t...

Deleting a vector from Available Vectors List 1728 1
Started by Deleted User
Hi,
I'm writing a program that makes changes to attributes of a vector.
But, no matter those changes are saved to a file or not, the changes remain changed unless I manually remove the vector from the AVL, or restart the whole ENVI session.
So, I like to know a function/procedure that removes a vector from the Available Vectors List.
(Or a function/procedure that updates/reload the vector from disk.)
Thank you.

1. Does anyone know how to make the editing keystrokes work I'm using OS 10.4 on a powerbook G4.

I'd like to apologize if this is a simple question, but I am new to IDL
and haven't had a lot of experience with it yet. I have some GeoTIFF
files created in ENVI (georeferenced MODIS imagery that has been

see if there is snow cover in some and not others. The images are
georeferenced and have common points, but do not have the same
dimensions or same complete coverage areas. So, I think I need to find
