2 Replies and 1164 Views Change default font for plot function  1164  2 Started by  Deleted User Hi, Is there a way to change the default font variables for the plot function I know that this does the trick: "For IDL's Graphics functions, use the FONT_NAME and FONT_STYLE keywords to select the font." But I'd rather change it once, then using these keywords every time I want to plot something. Thanks in advance, Wouter Schellekens

3 Replies and 1506 Views Last line of file problems  1506  3 Started by  Deleted User When I import data from a text file into IDL and uses it, then the data from the last line in the text file ends up giving errors. So there is some kind of end of file thing going on, that makes reading that last line of data go wrong.

4 Replies and 1322 Views IDL 8.2.3 crash windows 7 (x64)  1322  4 Started by  Deleted User Hi, I've upgraded my version of IDL to 8.2.3 a couple of weeks ago and I'm experiencing many random crashes. The IDLDE on windows 7 (x64) just quits during aspecific tasks. It mostly happens when I try to copy paste some code into the comand line. It doesn't give any errors or warnings; it just quits. I didn't experience this problem with IDL 8.2.2 or earlier versions. I can imagine that, given this information, it may be hard for you to figure out the problem, so if there's any further info I...

4 Replies and 1401 Views Is it possible to save RTV_DOIT output to disk as an evf file?  1401  4 Started by  Deleted User Hi, I'm trying to figure out a way to run SVM programmatically and for that I need to generate ROIs from a raster image. First, I create 2D arrays of the same size as the image to be classified, which value 0 and 255, where value 255 indicates a training pixel. Then I use the RTV_DOIT procedure to vectorize these data. However, it only outputs the results to memory. How can I programmatically access generated vector files In other words, can I save these files to disk or get their file ids so...

I am trying to write a simple code that will take single band tiffs as inputs (MODIS bands 1, 2, and 7 for each day in a ~2 week period), stretch each band based on a range of values which are already predetermined (linear stretch using absolute min/max input values), and then stack the bands to create a 721 false color composite for each date.

2 Replies and 1440 Views write_png in OSX 10.8?  1440  2 Started by  Deleted User I have a new OSX 10.8 computer that I'm using to run IDL 8.2.3. The command write_png,'foo.png',tvrd(true=1) no longer produces a PNG file of the graph I have drawn. Instead it reproduces the background and nothing else. The command worked great on a computer running OSX 10.6 and IDL 8.2. Can this be fixed or is there a workaround
