8 Replies and 1169 Views IDL 8.7 Mac OS X client corruption  1169  8 Started by  Patrick O'Loughlin I have IDL installed on a handful of computers running Mac OS X High Sierra. I installed the 8.7 version of IDL on about six of these machines. One installation showed the error below about a day after the install, and another one about two weeks after the install. In both cases the error was present for all users of the machine. Rebooting did not help the problem. I uninstalled and then reinstalled IDL 8.7, and it has worked since. I was hoping to get a better understanding of what may be causi...

However, I found that the array storing the gridded data cannot be shown normally on the map. The first column and bottom row are ignored when plotted on the map.

6 Replies and 2677 Views Resampling with MNF bands  2677  6 Started by  Stavroula Giannakopoulou Hello everyone, I have an issue regarding the IDL of ENVI. I apply MNF to spectra in order to resample my spectral library and then to insert those data to the environment of IDL. The error that occurs after the procedure of IDL refers to: Import spectra: an error has occurred during processing error variable is undefined: Y. The result may be invalid. I don't know how to solve it because it relates to the y-axis for which it doesn't recognize the variable. Any suggestion Thank you very m...

1 Replies and 113 Views Discrepancy in calculation of ATAN  113  1 Started by  Dulci Avouris Hello! I found that when I use the ATAN function and input two arguments that I get a different result than if I first divide the arguments, and then calculate ATAN. i.e: theta = ATAN(num, den)/4 = -0.54489 num = -2.48664 den = -1.7322 VS angle = (-2.48664)/(-1.7322) = 1.43454 theta = ATAN (angle)/4 = 0.24051 This angle is being used in a varimax rotation, and with a different result for theta, the resultant rotation is not correct. Please clarify what is happening here...

0 Replies and 46 Views Manually trigger widget events  46  0 Started by  Christopher Mendillo What I'd like to do with widgets seems simple, but I don't think it is possible due to the single-threaded nature of widgets. I have a normal IDL program running -- let's say it is reading images from disk and displaying them. I would like to use a widget to display the images so that I can take advantage of mouse click events. So, the top level program creates a draw widget, starts reading images and passes them to the widget using UVALUE. For each image, I'd like to manually trigger the ...

2 Replies and 86 Views Spectral Feature Fitting Function / PyIDL Bridge  86  2 Started by  agraham1 Hi all, I have not been able to find any documentation on the harris site referring to a callable spectral feature fitting (SFF) function. I am hoping to obtain a score between two spectra much like in spectral analyst, using SFF. Does IDL have this functionality and will this function be callable in Python-IDL bridge Any help is much appreciated. Kind regards, Alex

0 Replies and 70 Views Interrupt embbeded Java Thread with CTRLC  70  0 Started by  IKhokhriakov Dear L3Harris Forum, I have a question concerning using embedded Java processes into IDL (Java-IDL bridge). Specifically I need to catch and process CTRLC while executing long running Java process from within IDL. Just listening for Thread.isInterrupted does not work. The source code of the embedded Java library can be found here: https://github.com/hzg-wpi/idl2tango/blob/6e8cd9f1a340481f7505f23d1a1c39cb36e493dd/src/main/java/hzg/wpn/idl/PollDevStateAwaitor.javaL54 Thanks in advance.
