Opening a Communications (COM) serial port 1671 1
Started by Deleted User
I'm interested in opening a serial port connection on my computer to send text commands and retrieve responses. More specifically, I would like to access a COM port from a remote computer location, similar to opening a socket in IDL.
First, can anyone supply a few steps to opening a COM port for communication with a device, say on com1 or com2 Secondly, does it seem reasonable that this process could also be performed from a remote computer over a TCP connection
Many thanks. Jon

Curve fitting 1339 0
Started by Deleted User
Does anyone know how to do curve fitting using an image with several bands (>10) whereby the image values are the observed Y values, at given wavelength (X), and output the parameters (A0, A1, A2 ...) as images. eg for a simple linear model using least squares. All examples in IDL deal with only given values of X and Y, In other words, how can you the same using image as variables

Drawing smooth antialiased lines 1613 2
Started by Deleted User
Can anyone please advise me how to draw high quality, possibly antialised lines in the plot
All of the curves or lines plotted under angle come out jagged. It seems like the line or curve drawing algorithm is not very good or I may be missing some parameter that makes the smoothing possible.
Is there a code example sowhere
Thanks,
Alex

Hi, I'm an ENVI user and I had dowload your IDL application ilidar to test it with some lidar data. I have been trying to use it and I can do almost everything that I have readed on the users manual.

Also it doesn't keeps the original coordinate system, how can I solve this problem Is it possible to create a tif...

How do I insert programmatically a second legend into my iTool

The first of these works fine, the second fails with the message
'A visualizatino supported by the legend facility was not selected.'
I'd be happy to select a visualization, but I don't even know how to do that. I...

Hi
I've a (beginer)question concering Itools, and in particulat the Idlitimessaging class.
I am trying to set a progress bar, but I really don't know how to do.
I have tried the following code, but it doesn't work:

test=Obj->IDLitIMessaging::ProgressBar('test',cancel='cancel', PERCENT=40)
Could you give me a way to do that (just the idea) I will then use 'help'

interpolation with griddata but with bounds like krig2d 1611 0
Started by Deleted User
hello,
I would like to perform an interpolation (idw) with griddata but my problem is that I want to extend the the region interpolated define by min(x), min(y) and max(x), max(y).
I have tried to define my extented region with start, gridsize and delta kewords. But the result is sometime not good, and the reason is may be due to that the start keword (x_min_region_extend and y_min_region_extend) don't contain a value to interpolate.
I think this is easilly done with krig2d notably with...

idldoc improvements 1464 0
Started by Deleted User
It will be a great idea to provide source code for idldoc tool written by michael galloy.
There is now a little well identified problem in the production of idldoc-index*.html files that may be easily fix by Michael himself and I will be glad to contribute to a XML/Docbook ouput if people are interested.
Without source codes, we can't improve the very usefull tool.
