ASCII Plot 1265 0
Started by Deleted User
Hello,
I am a complete beginner in IDL so please bear with me. I am trying to plot an ASCII file.
I do the following:
First I find the path of my file using:
C:\Program Files\ITT\IDL71\desktop\overnight.lvm
'overnight.lvm' is the ASCII file. I then create a plotting template:
plotTemplate = ASCII_TEMPLATE( )
and then:
plotAscii = READ_ASCII(FILEPATH('overnight.lvm', SUBDIRECTORY= $
&91'desktop'&93), TEMPLATE=plotTemplate)
My question is. How do I point to the file using the fil...

how to call a matlab file(.m) in IDL? 1296 2
Started by Deleted User
Dear all.
I need to call a matlab file (.m) from idl. I know IDL can host the MATLAB COM object. For example: oMatlab = obj_new('IDLcomIDispatch$ProgId$Matlab_application_6') ;test in IDL6.2 with Matlab6.5
But I don’t know how to pass variable value and return value between IDL and MATLAB, and how to execute a matlab file (.m) in IDL.
Furthermore, can you tell me how to use Call_external function call a matlab file (.m) in IDL.
Would you like to give me some example codes
Thanks for your h...

IDLgrPolygon fill 922 1
Started by Deleted User
Hi,
If the vertices of a polygon are as follows.
x = indgen(12)
y = &915, 5, 6, 7, 8, 9, 8, 7, 6, 8,5, 4&93
thisPoly = Obj_New('IDLgrPolygon', x, y, Color=&91255,0,255&93)
thisPoly->SetProperty, STYLE=1
with Style=1 the polygon is created properly as expected.. whereas if Style=2 (i.e when filled), the filling is performed over the outer vertices. And hence these two do not look similar.. Is there any option to make the polygon fill by considering vertices as such and not by out...

Need a reversed X axis in object graphics 1244 0
Started by Deleted User
Greetings:
I need an x axis with positive values to the left. In procedural graphics, this is easy: &91 plot,&911,2,3&93,xrange=&9110,-10&93 &93.
With object graphics, if I don't use exact=1, then it reverses the range, putting positive to the right. If I use exact=1, the axis labels are mirror imaged and I have not yet found a way to scale the plot object to put the data in the view.
This is with idl 7.1.
Thanks...

IDL shortcuts (hot keys) and SCIM on linux 1192 0
Started by Deleted User
Hello!
A year ago I had some problem with IDL on my Ubuntu Linux box (it was 8.04):
All shortcuts (hot keys) in my widget program ceased to work. After a week of investigations I found that the reason was the new SCIM manager (Smart Common Input Method) introduced in Ubuntu by default. The problem was fixed by disabling all functions in SCIM.
After my last update of Ubuntu (to 9.04) the problem came out again. But now it can't be solved with SCIM configurations.
Does anyone have this pro...

Hi...I have some .mxhi (merged extracted high dispersion) files which i have downloaded from IUE site. Now in order to retrieve data i need to convert them into .fits format. I thought of using idl for that. Now there is a function readmx in idl which does that, which is available in idl libraries. Now, this readmx calls various functions...one of them is keygen.pro. I am able to read the .mx files but while writing them to a .fits file the problem arises.

Readu, Writeu only 32-bit on 64-bit system 1199 1
Started by Deleted User
Hello everyone,
I have created rather large 3-D binary arrays in IDL that I save as unformatted data using writeu. When the number of elements contained in the volume gets to be around 2,300,000,000 if I attempt to writeu or readu the volume, I am kicked out of IDL with a segmentation fault. I don't think it's a memory issue, I'm running 64-bit IDL on a 64-bit linux running redhat enterprise with 12 GB of ram, and I can save arrays that have larger file sizes as long as they have a smaller...

Dear all,
I am using the floating license of my institute under Linux. Currently there is only one license available (if one is working another has to wait). I need to run a simple script, however currently it will take 28 days to complete it.. So, I would like to take advantage of the empty cpu's waiting in the system.
But, I do not know if parallel processing is possible under idl. Even if so, I do not know how to write mine.. So, I wish to run the same script under 6-8 windows to get the re...

use ENVIIDL together 1353 1
Started by Deleted User
Hi everyone,
I have written a code in IDL which interacts with ENVI. The code works fine on a Windows system but I need to run it on an Linux system.
Is there a possibility on Linux to start ENVIIDL together like in the Windows system with the "envi_idl.exe" file Until now, with the Linux system, I can only start ENVI and IDL seperately which means that they can't interact together.
I hope that someone can quickly answer to this question:
Cheers,
Nicolas
