0 Replies and 51 Views 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 ...

1 Replies and 157 Views 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...

3 Replies and 193 Views 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 ...

2 Replies and 158 Views 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.

3 Replies and 2254 Views 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...

3 Replies and 231 Views Change Detection Difference Map  231  3 Started by  Christian Kohler 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. Filter Tie Points by Gl...

3 Replies and 283 Views 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...

1 Replies and 262 Views 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!

The rendering of images, lists and tables during runing the program is not a problem. It just sometimes take very long time to get the buttons visible to get started.

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...
