0 Replies and 6 Views reading and processing multiple bands into one big file  6  0 Started by  David Hein-Griggs Hello, I am helping a PhD student automate processing of hundreds of huge satellite imagery files. These imagery files have been split into individuals files per band in the process of correcting metadata in a previous step. These band files all have the same names -- only the directory names are different based on the name of the source satellite imagery file. 29/09/2020 00:31 644 alpha.bin.hdr 29/09/2020 01:24 419,576,868 alpha.bin.img &91;snip&93; 2...

0 Replies and 15 Views IDL 8.8 Workbench, icon sizes (Win10 x64)  15  0 Started by  Kip Matthews In upgrading to IDL 8.8.0 from 8.7.2 (on a Windows 10 64-bit PC), the icons of the buttons in the IDL Workbench (for New Pro File, Cut, Paste, Compile, etc.) are drastically smaller in size than they were in the 8.7.2 Workbench (very problematic on a UHD-resolution monitor). In the 8.7.2 workbench, one could right-click on the toolbar and get an option to show text on the buttons, or to use small small icons; the 8.8 Workbench doesn't provide these options. I don't see any settings in Preference...

0 Replies and 225 Views Widget focus  225  0 Started by  Jürgen Koglin Hello, I have several floating draw widgets. All these widgets have the same level hierarchy. Setting the input focus automatically on one of these widgets, when I move the mouse over it, works fine. Unfortunately, 'widget_control, /input_focus' does not only set the focus on the widget, but also brings the widget to the front. How can I set the input focus on the draw widget without bringing it to the front Which means, if applicable the widget should stay behind the others and not be pu...

0 Replies and 167 Views multi-thread warning command line?  167  0 Started by  Wouter Schellekens Hi All, Recently, I've been getting this warning when I run a script from the command line (not from within the developer environment): OMP: Warning 190: Forking a process while a parallel region is active is potentially unsafe. Quite often the script will hang and not finish when this warning comes. It sounds like there's an issue with multi thread processing, but I'm not sure. Anyone have any good ideas on this issue and how to solve it I'm running IDL 8.7.3 on x64 Debian GNU/Linux ...
