Bandpass_filter error message 8 0
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.

Possible bug in position property in graphics objects 88 0
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...

Mac OS compatibility for IDL 8.6.1 and 8.7 49 1
Started by Thayne Currie
Hi: I have an active, albeit old IDL License with 8.6.1 installed on an older computer running Sierra (OS 10.12). On my account, I also see 8.7 as a listed potential 'add on', although I do not see a download link. Questions: - if I upgrade my OS to Mojave (10.14), will IDL break (i.e. is 8.6.1 incompatible with Mojave) - Is 8.7 compatible with Mojave

IDL 8.8 not compatible with 8.6 code 96 1
Started by Achim Holtmann
Hi, in IDL 8.6.1 list({a:&91;1&93;}) eq list({a:&91;'1'&93;}) returns 1. In IDL 8.8.1 the same returns 0. This breaks my code that determines whether two structures are equal (as IDL cannot say {a:1} eq {a:1}). This (among other issues - see topic 'Fatal error with restored structure from sav file') definitely prevents me and my working group from updating IDL beyond 8.6. Will this be changed eventually to assure backward compatibility Thanks a lot! Achim

Need Optiminization help! 118 3
Started by Bill Biagiotti
I've been working at this dilemma for quite a while and thought I would ask my fellow IDL experts. I am processing an image by taking sequential 3x3 2D subsets from it and calculating the following: 1) Subtracting the center point from the surrounding elements, 2) Calculating the absolute value of (1), and then summing all of those deltas. The problem is I can't figure out how to efficiently do this with IDL without loops. Here is some code: n = statboxsize - 2 temp = INTARR(statboxsize, ...

.RUN not working w/o options in idl 8.8.2 511 3

Using .RUN in idl 8.8.2 does not give me a '-' prompt, just goes right back to IDL> . However if I do '.RUN --' then I get the '-' prompt. I do not see this issue with IDL 8.8.1 . Any ideas on how to setup 8.8.2 so I don't need to add '--' to use .RUN . Same happens to .RNEW . Thanks Chris

How to download IDL Virtual Machine 745 2
Started by Vittorio Torroni
Hello, I need the IDL VM to run a .sav file that has been given to me. I have completed the registration process, but I don't understand how to download IDL. If I go to download and licensing center, it says that I need to enter a specific username and password (not the same one used to register on the main website), but there is no link to create such account. I have tried to download old versions, but it says that the page is temporarily unavailable. It's very disappointing that l3harri...

Fatal error with restored structure from sav file 204 2
Started by Achim Holtmann
Hi, I use list(struct) eq list(struct) to compare structures. This works fine mostly but the code below produces a fatal error (IDL Workbench closes). Note that this only happens when the structure is set up in a certain way, e.g., with only the first two tags, it does work. s = {l: 1l, s: '', s2: ''} list(s) eq list(s) ; This returns 1 as expected save, s, FILENAME='s.sav' restore, 's.sav' list(s) eq list(s) ; this produces a fatal error I use IDL 8.8.1 on Linux Mint 20.3 Thanks...

Hello everybody, i am very new at idl programming but know the principles of OOP. Now i need a class with a few instances where each instance is able to access the same data.

UTF-16 Support in IDL 248 0
Started by Viji VL
In IDL 8.1 version, default encoding for workspace and resource file UTF-8. If we need to support surrogate pair (in Chinese environment), we need UTF-16 encoding. In UTF-8 encoding surrogate pair character is displayed as ''. But we could not change to UTF-16 encoding. If we change to UTF-16 encoding in IDL workspace file entries got messed up or IDL got crashed. Also even if we input surrogate pair character in widget_text control, GET_VALUE returns '' Please give support for UTF-...

HDF5 Question 240 1

Does IDL have support for 'dimension scales' in its H5 routines I see it in various Python, Fortran, and C implementations. But I cannot see anything similar in IDL's H5 routines. For example, the calls to H5DS at this thread: https://hdfeos.org/forums/showthread.phpp=1774 . Thanks for any input. -Marcos

QUERY_DICOM return zero for dicom files 363 1

I have some dicom files not being recognized as dicom by IDL, but recognized by other dicom readers/viewers. One example is from the newest softwareupdate for an x-ray vendor export raw images in a dicom format where QUERY_DICOM return zero. The file can be read by other software including MicroDicom and ImageJ so the vender claim that there is nothing wrong with the dicom files. Another example: Some processed images, both for old and new gamma camera, return zero on QUERY_DICOM. The files can ...

How to determine which US state a point is located in? 5482 0

There is no routine built into IDL to do this by default. However, it is very simple using the stock states shapefile and the IDLanROI object class: https://www.l3harrisgeospatial.com/docs/idlanroi.html See the provided example function below which can be used to identify the state containing the specified point: function stateFinder, longitude, latitude ; NAME: ; stateFinder ; ; PURPOSE: ; This function returns the name of the US state containing the specified point....

Plot transparency issue IDL8.8.2 332 1
Started by Wouter Schellekens
Hi IDL experts, When I plot symbols with the plot or scatterplot function, the transparency of the symbols is high. I cannot get it to zero, and appears to be transparency=50 by default. I can increase it to values higher than transparency=50. However, the issue only occurs when displaying within IDL and not when I save it to e.g. a png-file. I'd like to see my figures exactly as I would save them, so I'd know what I'm saving. How can I fix this I'm using IDL8.8.2 on Linux Debian 11 Tha...
