Python Bridge numpy absent 139 1
Started by Dagmar van Dusschoten
I recently installed IDL 8.8.3 and decided to setup the bridge to Python. I added to the PATH variable and ran setup.py in the correct directory. Everything looks OK. In Python 3.7.6 I can run from idlpy import * When I run in IDL > np=Python.Import('Numpy') I get PYTHON::LOAD: numpy is not installed for this python distribution and is required for the IDL-python bridge. numpy can be installed by running 'c:\users\d.van.dusschoten\Anaconda3\python.exe -m pip install numpy'. numpy is in...

Change Detection Difference Map 129 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...

python to IDL bridge on Mac 1993 2
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...

Scale all bands in raster 137 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 158 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!

Slow rendering at startup 1164 1
Started by Ellen Wasbø
I have an applikation with quite a few widgets in it, but I think it takes strangly long time to start up. 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. Are there anything I can do to my code to speed up the startup-rendering

Creating ROIs for a dataset and collect pixel values 1027 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...

Hi guys, My IDL program stops automatically at regular intervals, about 2 hours, although it can run successfully every time after I restart it. The error message is: Failed to open image.

problem saving graphics 964 1

Hi, I have the following problem when saving graphics on Windows 10 with IDL 8.7.2 I create a graphic and save it in a PNG file using the Save Method. A normal graphic can be seen here as an example: https://www.astroamateur.de/IDL/InetLayoutMOL40_ok.png From time to time, however, a graphic is created that sometimes shows bars instead of labels. Here is an example: https://www.astroamateur.de/IDL/InetLayoutMOL40_fail.png The faulty bars are usually in an identical position. Th...

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. I had several problems including incomplete IDL_PATH to access all libraries. Anyhow, I couldn't solve one problem: the function STRSPLIT. 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...

Using Symbol UValue 169 1
Started by Christian Kohler
Hi! As I did not find any possibility to show a colorbar for the Time Series Analyzer -> Vector visualization I wanted to recreate it using idl and the symbol function. But it turned out that adding a vast number of symbols is badly slow. By the way the whole ENVI program reproducibly crashes when interrupting a lengthy loop adding symbols. Therefore I wanted to add all symbols at once, passing x and y vectors to the symbol function and using the uvalue to set the symbol color. Would this be po...

Possible bug in position property in graphics objects 228 1
Started by Peter Montag
While working with some custom plotting routines, I found that setting the position property of a plot does not work as expected. Rather than the plot moving to those coordinates, it instead move something like 2/3 of the way there. For example, p=plot(&91;0,1&93;,&91;0,1&93;) p.position = &91;0.0, 0.0, 0.5, 0.5&93; p.position = &91;0.5, 0.0, 1.0, 0.5&93; will give a plot positioned at &91;0.314, 0.0, 0.814, 0.5&93;. Does anyone know what's happening here Is this intended beha...

Bandpass_filter error message 173 1
Started by Khilav Majmudar
I have 2D time series data, which means I have values in a plane that evolve. I would like to filter the data around the 5 mHz frequency and then plot it. The command I am using is: bp = BANDPASS_FILTER(array,freq0-0.004,freq00.004,/IDEAL). array is a two-dimensional array of values. freq0 is 5 mHz. This command is yielding the error message I mentioned in the summary. Any help is appreciated. Thank you.
