How to increase JVM Heap Size for IDL-Java Bridge? 1885 1
Started by Deleted User
Hello All,
I am having problem in increasing the heap size of the JVM when I call Java objects from IDL. By default it uses only 64MB, and hence cannot generate a large array on Java side.
I tried to set the JVM start option in idljavabrc file:
'JVM Option1 = -Xms200M'
'JVM Option2 = -Xmx1G'
but it doesnot work. IDL starts JVM with heap size of 64MB.
I use following code to check the allocated heapsize for JVM

Handling large arrays in IDL 2406 1
Started by Deleted User
Hello,
Can you give me some tips on how to handle large arrays in IDL. The size of the arrays that I am working with are around (100000 x 100000). One way to get around is to create many smaller arrays but I would like to keep this option as the last one. The RAM size of the server is also very large, 8 GB, which I guess is the maximum that could fit onto the machine. I would be grateful to have some suggestions from you.
Thank you.
Regards,

Geography_Student intends to create algorithm for Target Species Mapping 1531 0
Started by Deleted User
Hi IDL users
I want to create an algorithm for mapping species based on the methods I am using in ENVI interface. May I mention that I have not done nor do I know anything about programming.
My plan was to use ERDAS Spatial Modeller to create my algorithm. Having been introduce to ENVI, I made a mistake by assuming that it would have environments (for creating algorithms) friendly to non-computer scientists such as spatial modeller which has library of graphical models I am competent in...

I am trying to get idl to start a routine every 5 minutes, while the user of the program should still be able to work on a widget interface.
My program should run under a virtual machine environment, check for new data automatically every five minutes, and still allow data browsing by using widgets while waiting for new data.
I tried using void IDL_TimerSet(1000.*15.,refresh_routine,0,0) but only get 'syntax error' for IDL_Timerset. This happens in IDL 5.5 (as well as for 6.4 demo mode) on a l...

IDL: erase doesn't work if graphics window is covered on openSUSE with X11 1620 1
Started by Deleted User
Hi,
when I issue the 'erase' command, or when the graphics window automatically erases because the next plot starts on a new 'page', if any part (or even the whole) of the graphics window is covered by other windows, then the part that is covered is not erased. If I issue a plot or other graphics command, this will happily draw the expected output in the window, even in the covered part (though of course if the covered part still contains the remains of a previous plot because the erase has ...

Hi,
I have 3 images in envi format and each has a header file(.hdr). They are image1,image2,image3.
When i use the file_search method to run a program, it reads image1 and image1.hdr,..and so on. I don't want it to read the header file because its not an image. Unfortunately, ENVI doesn't have an extension for its file names and hence i have to delete the header files each and every time i want to run my program. Is there a way of specifying the method not to read the .hdr files or to read o...
