IDL: Fatal IO error 11 (Resource temporarily unavailable) on X server :0. 2495 1
Started by Deleted User
I use IDL 8.1 on ubuntu 12.04. This idl is running on server license and the desktop is connected to LAN.
I usually keep the idl program running for overnight. But, there is no guarantee that the next morning I will find the idlde session still running and not closed down. The idlde workspace tends to close down with the following error in respective terminal window "IDL: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.". For the same set of codes and accessed file...

Polyfill Speed Increase 1248 2
Started by Deleted User
Hi Everyone,
I am trying to increase the speed of a program in which I am using polyfill to plot out radar data range height indicators using elevation and range. Originally I was looping through each individual elevation and range and using polyfill to plot out that individual bin. I am trying to remove one of the FOR loops and pass a 4x500 array of x and y coordinates to polyfill. This has greatly increased the speed, but I am getting artifacts in the data. I am wondering if anyone else ha...

properties can&39;t be accessed within the class? 1241 5
Started by Deleted User
I have defined classes with properties through getProperty() and setProperty. It works fine in that other classes can access these properties on the class it defined them as well as on its subclasses. However, within the defining class (and its subclasses), the properties seem invisible (Tag name XXX is undefined for structure YYY). It seems as if "self" is only seeing the structure of its DEFINE. Is this by design, or am I doing something wrong here

help with function call syntax 1442 2
Started by Deleted User
Hi,
I'm a sysadmin, trying to restore some idl scripts after a system crash. It's been a LONG time since I've done any IDL development myself.
I'm running an old shell script that calls some custom idl routines, and am getting fundamental-looking syntax errors that look to me like the idl pro's were maybe written for an older version of IDL. I've installed the IDL that I thought was working on the system before the crash, but I don't know for sure. I've tried with IDL 5.6, 6.0, 6.3, 6.4 and 8.2....

how to fail an object&39;s INIT 1131 3
Started by Deleted User
I read in the documentation that when the constructor fails, INIT should return 0 rhather than 1. However, this seems to pass undetected and the program continues, albeit with an invalid object pointer. Should the result of obj_new() always be tested for validity, and if so, what is the proper way to do so

For loop bug? IDL 8.2 & 8.1 1178 3
Started by Deleted User
Hi, I'm experiencing what looks like a bug, in a simple for loop:
IDL> for i=0.,1.9 do print,i
0.00000
1.00000
2.00000
I see this in IDL 8.2.2 and 8.1, but not in versions before. Can anybody confirm whether this is a bug, intended behaviour or something else

E3de / Envi Batch Generation of Building Polygons and DEM/DSM 1407 3
Started by Deleted User
E3de or ENVI (depending on what version etc), has the function to capture building polygons and generate a Digital Elevation Model (DEM) and a Digital Surface Model (DSM) from a classified LAS file. Granted it can do more, however at the moment, just chasing these three.
I've been playing around with it and it seems as though it's more efficient in calculating a singular tile at a time, rather than numerous tile (perhaps also a limitation from the PC). However, I have nearly 10,000 tiles, pushin...

IDL script to applying transformation to image 1053 1
Started by Deleted User
Hi,
I'm working on a script that will take an image and the coefficients for a polynomial transformation and apply the transformation to the image. My script creates a new image as it's supposed to, but the coefficients I passed should just be a translation of 5 in the x direction and 5 in the y direction. Instead the image is all white with odd short diagonal gray and black lines all over it. Attached is my code and I was wondering if anyone could spot any glaring bug that I'm missing Than...

Unsupervised Classification 1285 1
Started by Deleted User
I've performed unsupervised classification (K-means) on a hyperspectral image. I had got 10 different classes and I brought it to bring it down to 6. For some parts of the image, the merging of the classes has worked out just fine, but in other parts of the classified image, even though I know that certain regions in the image belong to the same class, but they have been classified into multiples classes.
I can't merge these classes, because they'll affect the rest of the image.
So, my que...

8.2.2 installation on Windows 7 64 bit VM_SERVER_PATH, Java missing 1357 2
Started by Deleted User
I installed IDL 8.2.2 on a Win 7 64 bit machine. Starting IDL I get a message that idlde cannot be started because java runtime isn't in the VM_SERVER_PATH.. I mucked around with the idlde.ini file to try to point this to where the java is installed. Seems like IDL comes with its own java installation should I point to there I've tried a number of different ways. No luck. Can anyone who's done this successfully send me an example. I must not have the syntax right.
Thanks

On Windows, one must simply change the config file to point to the appropriate JDK.

Iterate over pixels 1170 0
Started by Deleted User
Hi There!
So, I have a RADARSAT-2 image. I need to generate polarimetric signature of the pixels to verify the location acquired using backscattering. I have marked the required locations using the ROI tool. Now, I need to iterate over the pixels to find out their polarimetric signature, and verify my findings. Is there a way to do so in IDL If so, can someone please provide a hint of a code or sample It will be highly appreciated!
