Screen rotation and visualization distortion 1621 0
Started by Deleted User
Hi,
I have a GUI with a 3D visualization that worked fine with IDL 5.0 and still works fine with 6.0 whenever the screen is horizontal.
But when I rotate the screen to have it vertically, and then execute my program, the volume is distorted. However, if I rotate once the volume is already displayed, it doesn't get distorted.
Anyone knowing how to solve this problem, please let me know.
Thanks

How to copy the content of a direct draw window into the clipboard in Linux 1650 0
Started by Deleted User
Recentely I swtiched from Windows to Linux and found out that the Linux version of IDL is quite a bit behind the Windows version considering the GUI. No color coding, cut and paste shortcuts do not work, mouse scroll wheel does not scroll the text, etc. My biggest problem is that I cannot copy the content of a direct draw window into the clipboard. In Windows I just used CRTL-C and then pasted the content into a word processor or a presentation software. Now in Linux when I click on the draw win...

multi-input spectral cancellation 1755 0
Started by Deleted User
I am trying to find IDL code for frequency-domain cancellation of N independent time series vs 1 dependent time series. For example, I may have 5 ancillary sensors that I'm using to remove the noise from the signal on a different sensor, and I wish to do the cancellation in the frequency domain. Does anyone have canned IDL code to do this

text widget fonts and colors 1805 1
Started by Deleted User
I would like to know if it is posible to change the font (and hopefully color) of
the text in an editable text widget after it has been created. I would like to
either change the font, or overwrite the text in the widget with text in a new
font. Is it also possible to change the color of the text
I can't seem to find anything in the documentation that makes it seem like
this is possible, but it sure would be nice in my application!
Many thanks to anyone that responds

This is strange - why would Save As stop behaving? 2061 1
Started by Deleted User
Using IDL6.2 on a WindowsXP machine. I'm editing an existing PRO and want to give it a new name - I just choose 'Save As' right However, rather than getting the expected dialog box so I can specify a new name, it just saves the edited file with the same name - as if it is behaving as 'Save.' Of course, I've done nothing different (of which I'm aware). Is this an IDL or Windows issue Maybe a reboot is in order...

dividing arrays of different sizes within a for loop 1910 1
Started by Deleted User
The code below is a diluted version of the one that I am working on. Basically i would like to divide each element of a 40 element floating array by n.
n refers 512 single arrays. I would like all this done within a for loop of 0, 511 so that the 40 element array would be divided by one n per increment in the loop.
In the end I would like each of the 512 40 element arrays to be plotted against 512 arrays of 40 elements each. However I seemed to be stuck.....any ideas
thanks

How to produce some latex symbols like \overline{X} ? 3275 1
Started by Deleted User
I find the textoidl package can not do this.
If i do something like :
'
a=textoidl('\overline{X}')
plot,findgen(100),title=a
'
It just give the title of the plot to be '\overline{X}'.
What I really want, however, is the title to be 'X' with a dash over it
So, how could I do that
Any solution will be highly appreciated.
