That is the ENVI idl run-time (virtual machine) is invoked to run the SAV in the aspx page. While the application is ok when I run it through Visual Studio debugging environment, It can not be run after publishing the website in local host (i.e. http://localhost/myWeb ). I don't know what the reason is and I will be appreciate if anybody could help me.

1 Replies and 222 Views Issues with the MEAN function  222  1 Started by  SH I am stymied by something that IDL is doing in my code, and I cannot explain it. I am calculating the mean (average) of a defined subset of an array (using an index defined by the where function), and I am printing out the mean as well as the number of elements in the subset for which a certain condition is met. If no element meets the condition (index = -1) , I would expect the mean to come out as NaN. However, IDL always returns a number. I thought something was wrong in my elaborate code, but...

1 Replies and 136 Views Changing Font Size and Type in Axis Titles  136  1 Started by  Josh Colwell p.title.font_size=value works fine to change the main title font size, but I don't see a way to change the size of the x axis and y axis titles. Also, what font was used prior to 8.6 I think the new one looks terrible, and it seems to be drawn differently: it's blurry and not as crisp and clear as in previous versions.

1 Replies and 154 Views Controlling vector maps with VECTOR and LEGEND  154  1 Started by  Simon C. Hi everyone, I am trying to draw vector maps with IDL from a list of vector catalogs by using the VECTOR and LEGEND functions. However, I encountered two frustrating problems that may force me to find alternative methods in order to get publishable results. First, let me explain what I need to do: I am trying to compare on the same plot two vector catalogues containing information about astronomical polarisation vectors. These vectors are plotted on top of a contour map of the astronomical...

1 Replies and 123 Views Changing PLOT Function Font back to 8.5 values  123  1 Started by  Josh Colwell The new IDL PLOT in 8.6 has new fonts and size for the titles. I can change the font size on the main title, but I don't know how to change it for the XTITLE and YTITLE. The new text looks fuzzy as well, not as crisp as original. What were the default font and font size prior to 8.6 and how can I change it back to that for all PLOT title values

0 Replies and 223 Views Question about IDL Legend  223  0 Started by  David Starbuck Question from customer: Is there any way to mix a line and a single symbol in a legend You can reduce the number of symbol by setting the SAMPLE_WIDTH to zero, but then the line will disappear. Possible Answer: Unfortunately, I think the only way to reduce the number of symbols is by adjusting the SAMPLE_WIDTH. You can then use the POLYLINE routine to manually draw the line onto the legend: IDL> theory = SIN(2.0*FINDGEN(201)*!PI/25.0)*EXP(-0.02*FINDGEN(201)) ...
