how obtain more informations about a .dicom file with IDL? 2845 0
Started by Deleted User
Good morning for all
I am working with the IDL language and i need to know the time acquisition of an image format (.dicom). i have used the query_dicom function and the (print, info) expression but i did'nt obtain what i wanted.
i have just obtained: info.dimensions, info.channels, info.num_images, info.image_index and info.pixel_type.
Can you help me and tell me if there is a function other than query
Thank you

Chirp-Z transform 3015 0
Started by Deleted User
Hi,
I want to implement an inverse chirp-Z transform that will take bandwidth limited frequency domain data as an input and output a given portion of the time domain. Is there any code out there that will help me &91Currently I use a zero-padded iFFT, this is very slow and introduces a lot of noise; any alternative to this would be good&93

Reading Binary Files in IDL 3738 0
Started by Deleted User
I have a binary file that I need to read into IDL. It has a structure:
80 byte header &91string&93
4 byte &91integer&93
then for as many times as are equal to the above integer:
12*4 byte &91floats&93
2 bytes unused ('padding')
What I wish to do is to read in the header, the integer, then read the floating point numbers into arrays of length of the integer. Unfortunately, IDL documentation (and I will not mince words) is absolute crap, and I cannot figure out how to implement...

Pointers in Objects 2771 0
Started by Deleted User
I want to create objects where the size of the data is not known and it is only been set at run time. That can be done with pointers but when you create a pointer as a data members IDL set it to a NULL pointer at initialization and then you cannot change it afterwards. How can I remedy that

5.6 & OSX: graphics woes: how about Apple's X11? 2678 0
Started by Deleted User
Direct Graphics does not always display properly under Orobor at least on several TiBooks. This example produces nonaccurate graphics:
x=findgen(1000)
y=cos(x/5)
z=xy
tvscl,z
The way the system behaves makes it look like a rendering problem, but neither hardware nor software rendering works properly.
I'm playing with Apple's X11, used for awhile by a colleague with good results. In this case Object Graphics crashes IDL and sometimes even X11 with hardware rendering, but appears s...

funny results for landscape metrics 2779 0
Started by Deleted User
I'm using version 5.5 and I've written a program to calculate various landscape metrics from a random array. I'm getting good results when the size of the random array is (50,50), (100,100), (500,500), but when I make the array (1277,1654) which is the size I need, I get odd results. Below is part of the code and the problematic results, the rest of the code seems to be working fine.
patches = max(regions)
patch_sizes = 0

Playing sound files with IDL 3418 1
Started by Deleted User
I would like to play sound files with IDL. Is this possible
I can read and write .WAV format sound files using the READ_WAV and WRITE_WAV subroutines but I can't figure out how to play these files.
The actual format of the sound files is not that important to me. Ideally, I would like to be able to play .WAV files but I would be satisfied if I could play any format of sound file.
Thanks.

Spawning an IDL application from a link on a webserver 2980 1
Started by Deleted User
I would like to hear from anyone who has already
done this or thought about the possibility.
If doing this has become fairly common, does RSI
have any utilities to facilitate the process
At his point I would think that I could bring up
a web form to gather all the necessary input
parameters, format that information in a file that
could then be passed to an IDL program that allows
for a 'batch' mode of operation.
Thank you.

Conversion to type double -- problem with READS procedure? 2969 1
Started by Deleted User
I have an ordinary ASCII data file formatted in columns with whitespace between them. So, I've been using the IDL 'READS' procedure to import the data into IDL variables. However, after some hunting for errors propagating through the code, I discovered that the 'READS' procedure was truncating the double-precision variables into float variables before storing them in my type double array. (The numbers I'm using have up to 13-digit precision.) I've been trying to find reasonable ways around this,...

'In fact, IDL users have already had success with distributed processing with IDL by
taking advantage of larger existing frameworks such as PVM or MPI.'
I tried to find an example or an example code but was unsuccessfull. Could you suggest a place to look or is anyone having a sample code for this I am trying to see if I can use I...
