Hello,

SQL Access questions 2136 0
Started by Deleted User
I am new to IDL and I am trying to create a database interface module using the dataminer functionality. The documentation and online tech notes appear to be very sparse on this topic, so I am hoping I will find a user who has worked through some of my issues.
Immediately I am trying to get a recordset working that is based on a ExecuteSQL statement so I can limit the retrieval from the database to specific records. My query appears to work (no error reported), but the first record retreived ...

IDL6.1 on OSX 10.4 Tiger Server 2032 0
Started by Deleted User
I installed IDL6.1 on OSX 10.3 (Panther) and on OSX 10.3 Server, and everything worked fine. Then I did an upgrade to 10.4 (Tiger) on my PowerBook G4 - again, this worked fine. However, when I upgraded to OSX 10.4 Server on my desktop G5 and G5 server, I get a segmentation violation as soon as I try to fire up idl or idlde.I suspect that there is a library conflict somewhere, but it seems strange to me that it works on 10.4 but not on the server version of 10.4. Any suggestions

How do I save a BINARY_TEMPLATE? 2012 1
Started by Deleted User
I'd like to use BINARY_TEMPLATE to extract header information from a binary file in IDT XVision's Multipage Raw (MRF) format. I want to save the template so I can use it repeatedly in the future without going through the template gui again ... the help file says I 'can' save a template, but I can't figure out how.
Any help would be appreciated!

Exporting images to ArcGIS format 2006 1
Started by Deleted User
Hello,
I am a new IDL user and I can't figure out how to export images in a form that can be read by ESRI's ArcGIS. I have tried using write_tiff with the geotiff command, but I don't understand what the format of the geotiff statement needs to be. I'm also wondering if using a geotiff is the best way to transfer the data or whether there is a better alternative I would really appreciate any advice!
Cheers,
Jessica

Creating an array of structures of arbitrary dimensions 1656 0
Started by Deleted User
Hello:
After going through the IDL help files I still haven't found a way to create a matrix of matrices in which the main matrix can be initialized to some arbitrary dimensions (n,m). I was also wondering how the indices within the sub-matrices could then be called. Any ideas
Thanks in advance

rotate with IDL 2001 0
Started by Deleted User
Hello,
I currently treat images ASAR and I would have to like to know how I could make to turn them of a some angle (36° example). The problem which I meeting is as follows, there is a function well ' rotate_doit' which makes it possible to turn the image but with preset angles and the function ' rotate' of IDL does not function (IDL don't can open an image ASAR). If somebody can help me that too will not be.
Thank you in advance.

Catching events while GUI is blocked by amoeba 2146 0
Started by Deleted User
I've got a gui which starts a lengthy minimization process using the function amoeba. I would like to be able to stop amoeba by clicking on a stop button in my gui. How can i capture gui events while amoeba is running. I've inserted code into amoeba while loop to catch events, but i'm unable to generate events while IDL is preoccupied with amoeba even with the no_block option passed to xmanager. Any suggestions

BBEdit/Codeless Language Modules 2240 0
Started by Deleted User
Dear All,
I notice that in the latest release of BBEdit 8 for Mac OSX there is a provision for Codeless Language Modules that are written as plists. This provides a (relatively) straightforward hook to color coding IDL syntax in BBEdit. As a profoundly lazy programmer who does not really want to understand the XML formatting of plists I was curious as to whether anyone knew of a Codeless Language Module that had been created to color code IDL syntax in BBEDIT.
Thanks,
Brian

error in iimage command! 1966 0
Started by Deleted User
I have two data sets to draw using Iimage.
Each data set has different Max and Min data values and I want to draw these two data with same scaling factor. When I draw each data set using Iimage, Iimage automatically scales Min and Max value to 0 and 255 respectively. Because Max and Min values are different from each data set, the scaling factor is also different.
To fix this, I did the following to one of data sets to match the scale.
Operations -> Transform -> Bite scale
