Array has too many elements error 3269 2
Started by Deleted User
Hello,
I have the following lines in my code for calculation of mean values in a ROI in a 3-colour image:
TV, I_disp, TRUE=1
ROI=CW_DEFROI(WG_Window_I, IMAGE_SIZE=&91500,500&93, OFFSET=&910,0&93)
ROI_X=ROI MOD 500
ROI_Y=ROI/500
M=mean(I_disp&912, ROI_X, ROI_Y&93)
When I select a large ROI (2500 points) in a 500x500 image with CW_DEFROI, IDL returns an "Array has too many elements" error in the last line "M=mean(I_disp&912, ROI_X, ROI_Y&93)"
I would...

Problem starting idlde 1572 2
Started by Deleted User
Hi,
I am currently experiencing problems loading the IDLDE 7.06 from my login on our server, but no one else seems to have the same problem which is really odd. We currently use SuSE Linux 11.3, and while I can run IDL from a terminal if I try and run IDLDE I get to the splash screen, choose my workspace and then I see the following error message:
** (bug-buddy:1500): WARNING **: Couldn't load /etc/xdg/autostart/ksmolt-autostart.desktop: Invalid key name: X-KDE-autostart-condition&91$e&9...

Hi all,
I am porting (well, I am trying...) my old IDL 7.1 program to IDL 8.0

The working old code is:

IDL Graphics Window Object 1481 1
Started by Deleted User
Hi IDL forums
I am fairly new to IDL and object graphics, so here is my problem. I hope you guys can help!
I am trying to find the object window that the IDL intrinsic plot functions send their objects to. I want to overlay a group of IDLgrPolyline objects onto the IDL contour plot and vector plot. The reason I want these overalayed onto the intrinsic plots is because the window is resizable and I can plot a vector field (I don't know how to do this with object graphcis). The reason I ...

Dear all,
I would be grateful if someone can help me to create a program for cluster analysis. I know the CLUST_WTS function but I don't understand what is the format of the input file.

Then, I would like to calculate a number 'n' of clusters with the representative paths (latitude and longitud...

Bug report writing to hdf-files: 1356 0
Started by Deleted User
I recently tried to write some data to an hdf-file. I created an hdf-file and started adding a whole list of different arrays containing data. IDL crashed and gave a coredump. After some debugging it turns out that when the length of filename or pathfilename exceeds 120 characters, writing several arrays to the hdf-file results in a crash. For 119 characters or less this does not occur. Note that a langth of 120 characters is not that unusual if you have a long path for a data directory.

Hi, I'm not quite sure what is going wrong in my code so hoping for some help please.
I have a .txt file that has been output from a different program which I want to read into IDL. The file itself looks like:
x
1 circle
2 square
3 square
4 circle
The first line which has an 'x' is just a dummy line that the program puts in and can't change. The commands I'm using to open and read the file are:
openr, 1, 'filename.txt'
readf, 1, object, shape

Beginner - Don't even know where to start - IDL and Batch 1501 0

I'm a beginner to IDL. I"ve been using the ENVI gui for a year, but IDL 4.7 is foreign to me. I think I need to use it because I have 150 MrSid aerial images that I need to classify in some sort of batch mode. I could also mosaic them, but envi freezes every time I try to mosaic more than 10.
I'm first looking for a resource on basics of how to use scripts people provide in the forum. The only thing I know how to do in IDL is open via the GUI in IDL 7.1.
Here's my plan.

Picking data points inside a IDLgrPolygon 1014 0

Hi all,
I am doing a visualization application and I am picking some data on
the surface of IDLgrPolygon defined spheres. The procedure which

Celestial Sphere), seemingly I am not able to pick "interior" points
of the sphere, since they are not recognized. I cannot think about any

Plot without axes? 2698 1
Started by Deleted User
This feels like it should be trivial but I've been stuck on it and trying messy workarounds for too long, so here goes: how can I make simple plots (PLOT command) but with the axes either omitted or at least freed from tick marks AND all text
The best I've been able to do is first plot with normal axes, and then overplot with AXIS using YTICKLAYOUT=0 and COLOR set to the background colour, so the desired axis gets overwritten with the background colour and vanishes. This doesn't work well ...
