Need additional optiminization help! 51 0
Started by Bill Biagiotti
I have another efficiency question for my fellow IDL experts. I am calculating the 'entropy' of many sequential 3x3 2D subsets within an image by performing the simple calculation of finding the MIN and MAX of these subsets, calculating the delta, and storing it in an array and the BYTSCLing it to display. This is a little different from a question I posted last year when a poster (Ben) gave me a very nice IDL way to solve it. Unfortunately, it doesn't lend itself to this problem. Here is my ...

IDLDE on macOS X11 display not forwarded 157 1
Started by Chris Stuberg
I'm having some issues with IDLDE 8.8.3 not forwarding the Workbench window over X11. Instead, `idlde` launches Workbench on the host machine not the client machine. I'm using a MacPro as a host running macOS 11.7. I'm using a MacMini running macOS 11.7 as a client. XQuartz version is 2.8.3 for both machines. From the client, I can ssh to the host and run `idl` from the command line just fine, and it will forward plots without any issues. However, when I run `idlde` from an ssh session...

Keyboard accessibility: new windows in IDLDE 193 3
Started by Anna Malanushenko
Hi, for some years now, whenever I type 'window, &91;number&93;' in IDLDE, the window it opens is (a) minimized, and (b) at the very very end of the AltTab sequence. This essentially makes it terribly inconvenient to switch to from the keyboard. Is there any setting that can help Is there a workaround My workflow often requires me to run a program, click somewhere on an opened window, then flicker between window 1 and window 2 (for example), then go back to IDLDE, then run a ...

program routine arguments as lists and hashes 158 2
Started by Evan Fishbein
Does idl have a syntax like python when arguments and keywords can be accessed using lists (*arg) and dictionaries (**kwargs). I'm trying to write code that cycles through the supplied arguments and it seems that builtins like print, string and create_struct have this capabilities, but user written routines do not.

python to IDL bridge on Mac 2254 3
Started by Stephane Erard
Hello I have a hard time trying to make the python bridge to work on Mac (OS X 14.2 localized, IDL 8.7.1, python 2.7 and 3.6) I'm using either the Apple install of python 2.7 or a homebrew install of 3.6. The IDL to python seems OK with python in the PATH (I can call python from IDL command line, although not in the workbench), but not the other way around. - Defining a PYTHONHOME logical only results in complete blocking of python (exits with message ImportError: No module named site...

Change Detection Difference Map 231 3

Hi! Currently I am investigating differences in some data, in case two DEM files. Therefore I used the Change Detection Difference Map dialog in ENVI which is working perfectly fine and fast, but as I want to use it several time I am looking a possibility to recreate this functionality in IDL. Trying to recreate the functionality in IDL I used the following functions (firstly using ENVI modeler and then exported to IDL): 1. Generate Tie Points by Mutual Information 2.

Scale all bands in raster 283 3
Started by Federico Carotenuto
I am trying to perform in IDL an operation that is conceptually quite simple, but that's apparently very complicated code-wise. I have a raster with more than 200 bands. The raster data values are 'float' type data and range between 0 and 1. I want to convert this raster to have 'uint' data type scaled between 0 and 10000. Conceptually this would be as easy as typing 'fix(raster*10000)', but that does not work, band math is needed. Now, is it really possible that this is the -only- way to...

VECTOR function doesn't make plot on postscript device 262 1
Started by Xinghai Zhao
I am using VECTOR function to make vector plot. But the resulting plot is always showing up in separate 'x' window even if I set device as 'ps' as postscript. The postscript file generated has zero size. I use IDL 8.8.2 on M1 Mac with macOS 12.6. This seems the case on other systems too! Thanks a lot!

Creating ROIs for a dataset and collect pixel values 1217 1
Started by Bereket Mamo
I am doing remote sensing work and have a dataset containing a few hundred images. Each image has several bands, which contain information such as reflectance, incidence angle, longitude and latitude information. My goal is to create a database of reflectance and other information contained in the other bands on a pixel-by-pixel basis. 1. To reduce the large amount of data this would generate, I would like to create a region of interest (ROI) around a specified location of the surface and ap...

Hello everyone, I am a beginner in IDL language and I need it to use the ACIS Extract package. After instaling the IDL and the reauested libraries I tried to do the tutorial example of the package.

At some point, a procedure of the ACIS Extract package used this function and it raised an error 'Variable is undefined: STRSPLIT. Execution halted at: $MA...
