Reading multiple image files 1318 1
Started by Deleted User
Hi!
I want to make a classification of a large number of images (640) with the same parameters, and I think that the best way is using a loop. But I don't know how to make than IDL open diferent image files and later. put a diferent name to all output information generated. The image's names are like 'IMG_001', 'IMG_002'... to 'IMG_640'.
How can I do it
Thanks for your time!

Length of minor tick marks 1713 1
Started by Deleted User
Hi !
I would like to modify the length of the minor tick marks in my IDL plot. For Major tick marks there is the 'ticklen' keyword. Is there a 'minorTicklen' keyword How could I obtain a minorTicklen=1.0 (i.e. minor tick mark for one side to the other on my plot, similar to ticklen=1.0) on my plot
Thanks for your consideration.

Problems with structures 1204 1
Started by Deleted User
Dear All,
I'm currently trying to read in a .fits file into IDL (this is being done using a routine called MRDFITS which reads the .fits file into an IDL structure). So far I have been able to obtain information about how many columns and rows are within the structure (n_tags and n_elements) and then used this to simply create a double precision array of the same size.
I now want to transfer the data from the structure into the array.
For instance the first line of the structu...

passing parameters to IDL executable 1325 1
Started by Deleted User
Dear Users,
I was wondering whether it is possible to create an IDL executable which requires the person executing the code to also pass a parameter. For example:
idl -rt=executable.sav 'working/directory'
In this case, the executable would take the string parameter with the working directory information and use it.
First, I would like to know if this is possible. Second, what needs to be done in the code to make this possible and three do I have to use some special keywords when creating ...

IDL Java Bridge -- Packaging class files and IDL files in a single war (or jar) file ? 1253 1
Started by Deleted User
Hi all,
I'm currently developing web-services for some IDL applications. To do so, I'm using IDL's (java) bridge technology. Besides, I store the IDL files to which these web-services provide access at a separate location, which has been added to the IDL_PATH. So far so good.
A disadvantage of this approach, however, is that I can't package one .war file that contains the class files of the web-service as well as the IDL files that will get accessed through this service. Instead, I first n...

Simple question on path 1208 0
Started by Deleted User
Hello,
I am compiling running an ABC.pro in a given Linux directory. ABC.pro calls other procedures, lets say 123.pro, which are located in the same directiory as ABC.pro. At run time, I get an error saying that the '123' variable is undefined.
How can I solve this problem I went ahead and opende the 123.pro and compiled, then went back to my ABC.pro and it went well. How can I avoid the manually compiling 123 (or other procedures needed by ABC.pro) on the fly
Thanks!
