printf within time interval 1436 1
Started by Deleted User
I am fairly new to IDL and need some help with coding a specific task. I have a data file with time intervals that I read in from one text file (file A with i elements). For example, the time interval vectors are 'timestart' and 'timeend' and they each have the form FLOAT = Array&911, 78&93. The times are in utc seconds. These two vectors form the time interval (i.e. timestart&91i&93 and timeend&91i&93 where timestart&91i&93
Any help with exampel code related to this task would be grea...

multiple lines pasted into console from DE editor don't run 1663 5
Started by Deleted User
Hi. I've noticed another problem with 8.2.1 DE that was non-existent in 7.1 There seems to be an issue with copying lines of code from a file open inside the editor into the IDL console. I often like to have programs open in the editor and I debug by pasting various lines into the console and doing some real-time manipulations.
However, when I paste multiple lines of code into the console, they do not run. They appear to paste just fine but the actual code doesn't carry out. And when I pre...

Read binery file 1148 2
Started by Deleted User
Hi
I got a problem with loading a binary file with IDL. I cannot read data with different byte order. In the header of ENVI standard file "byte order" is equal to 0 or 1 (Host, Ieee respectively). The default value for reading data with binary_read is 0, but how can I change it to 1.
There are some other function to read binary data but I do not know which function or program can read binary data with different byte order.
thanks a lot.

Scale and resolution of the image capture by aircraft, 1344 1
Started by Deleted User
Scale and resolution of the image capture by aircraft,
I’m wondering if there is a mathematical relation between the scale and resolution of the image captured by aircraft and thus the attached table can be justified:
(sorry i couldn't insert the image here or even attach it)
Mathematically, the scale of the image captured by the aircraft can be obtained from the equation:
Scale = 1/(H/f)
where H is the flying height of the aircraft and f is the focal length of the cam...

How to quickly draw red-NIR scatter plot? 1350 4
Started by Deleted User
I want to extract the soil line by IDL, a scatter plot of red-NIR is needed. Although the following code is working, however, it's very slow for a large image or high resolution image because repeated drawing of many coincide points.
PLOT,B3,B4,LINESTYLE=1,PSYM=3
When I directly plot the red-NIR space in the ENVI, I found it very fast even for a very large image. Can you tell me how to solve this problem

active plot window remains in front? 1156 3
Started by Deleted User
In IDLDE 7.1, once an active direct graphics window was open, it was possible to input commands into the IDLDE console while keeping the active window "up front" (or "on top") so that you can make plotting changes on the fly and see it update without making the IDLDE active and "on top", thus covering up the plotting window. This was nice because they could overlap each other on the monitor but I could still easily make real time changes and see the results. This ...

Inverse matrix is failing 1274 3
Started by Deleted User
I have a matrix N
N FLOAT = Array&913, 3&93
With the following values:
10.0000 5.45787e006 3.55141e006
5.45787e006 2.97883e012 1.93831e012
3.55141e006 1.93831e012 1.26125e012
When I take the inverse of the matrix:
u = INVERT(N)
The inverse fails,
Because the result of
uN
0.894347 1.52182e-006 5.25777e-007
-512203. 1.79728 0.227137
-231619. 0.543829 1.14051
Does not give a 3x3 identity matrix.
Any ideas
Thanks

use of temporary in IDL 1104 0
Started by Deleted User
I had a question regarding the use of temporary in IDL.
I wanted to re-order a 3D array.
Suppose the array is vol = IntArr( 512, 512, 287 )
I sorted the Z dimension and got the indices. The command I then used was
vol = temporary( vol&91 *, *, sorted_z&93 )
Despite this, the memory used is still the same if I don’t use temporary (almost 5 times the size of the array)Is this the correct way to use temporary If I am using it correctly, is it just the IDL way of reading columns and r...

I am running the IDL Workbench 7.1.1 with Windows XP-Pro.
I would like to start the Workbench from the command line and specify the Workspace. Is this possible
If you like details: I repeatably run the same IDL sav file on multiple machines at the same time without an operator. This sometimes fails because there are not enough IDL licenses. I can recover: after one hour, the calling program gives up, kills IDL, and restarts it. But, I have noticed that if I start the IDL Workbench first, ...

Is there a way, using the current plot-function, to apply multiple colors for the FILL_BACKGROUND option
For instance, let's say I want to fill the area under curve, bigger than zero, with red and the area under curve, smaller than zero, with blue. How would i do that, without having to break up my data and make two separate overlapping plots
