Sorry... We have file_lines for lines(rows) in IDL. What about file_columns? 1495 1
Started by Deleted User
I posted similar message below yesterday, but I am really sorry for my language mistake. English is not my mother tongue, and my language is totally different from English. For this reason, I am doing this kind of stupid mistakes sometimes.
I rewrote my posting. Please understand me... Please ignore the other question below. T.T
What I was trying to know was on 'file_columns'. We can easily figure out how many lines(rows) in IDL using File_line function. However, at least in my knowledge...

Started by Deleted User
I know there is an excellent functions to count the number of lines of data file...
What about file_rows Is there any functions to check the number of rows
If there is no functions, what do you do if you want to have the number of rows of a big data file, for example, (*, 169245)

Using CVS with IDL 1301 0
Started by Deleted User
I'm looking to add version control to my IDL projects. I want to use CVS tags to update the Revision number (and other things). But I also want to be able to display a dialog at start-up with the revision information from all the source files in the project. I have created a variable at the beginning of every file:
rev = '$Revision$'
My question is, how can I extract this variable from each file in the project so I can display the information at run time I see this as a scope problem. But e...

Change 640x240 array into 320x240 array using pixel values 1525 1
Started by Deleted User
I have this 640x240 array i need to change into a 320x240 array. However, i need to use th info of the first array, values of the pixels and compute them together to be able to obtain value for pixels in the second array (values of 2 pixels correspond to 1 pixel in the 2nd, hence double width). Is there an easy straightforward way of doing this without resorting to too many for loops.
thanks

IDL runtime call ENVI routines 1467 1
Started by Deleted User
Hi,
I am trying to write some program that can run in IDL runtime that uses ENVI routines. I have included the following code
ENVI, /restore_base_files
ENVI_batch_init
The program runs fine in IDL IDE mode but when I exported as a standalone *.sav file, it calls up the ENVI menu and stops.
Does anyone share the same problem

generating a 3D array of .tiff images from a set of several separate .tiff images for use in mpeg creation 1504 1

Hello,
I have three sets of 20 previously generated .tiff files (400x300 pixels each). I would like to stack them into three 3D array files so that I can create three mpegs, however I'm running into problems, specifically I think I am running out of logical units. I'm rather new to IDL and I think this is a relatively simple problem to fix, probably something wrong with the syntax. Here is what I have so far to generate the first of the three sets:
