IDL 8.4 : SERIOUS problems with save files 1930 3
Started by Deleted User
Good morning,
I am running IDL 8.4 on a windows 2008 server machine. I have two problems with the save files I am creating:
1. Even though I am including the exit, /no_confirm, command before the end command at the end of the program, IDL does not exit. I.e. the save file starts, runs, executes and then just sits there. If I simply run the same code properly, i.e. open, compile, run, then it executes and at the end, exists IDL. From the save file, it does not. Any ideas
2. Why do the save file ...

Issues with Legend function 1901 1
Started by Deleted User
I'm adding a legend to a plot using the legend function. The legend shows the correct name and symbol for each data set, but the symbol appears three times in front of the text instead of just once. Does anyone know how to get a single symbol in front of the text in the legend I'm calling the function as follows:
MIPS= PLOT(MIPS.Sersic_Index, MIPS.BT_ratio, XRANGE=&910,8.0&93, YRANGE=&910,1.0&93, $

Started by Deleted User
Dear Sir
I wish to save my graphics directly to a image file (file format is not important), as first displaying it in a window and then saving it to in image file takes a lot of time. Is there a way this can be achieved. I am using IDL version 8.2.3.

Issues with ENVIRaster 2200 4
Started by Deleted User
Hi,
I am using Envi 5.2/IDL8.4 and try to get used to ENVIRaster functionalities instead of the old reading and writing routines but struggle with some points.
1. When I try to use ENVISubsetRaster to get a subset with its spatial references (see code below), it shows spatialref as undefined in the variables list. According to the help article, this should work. It also works when I use "spatialref = in_sub.spatialref".
Is it directly implemented in ENVISubetRaster or not
Also, the ...

IDL 8.1 on Mac OS 10.10.3 1879 1
Started by Deleted User
I have a license for IDV v. 8.1. I updated with 8.2 but I cannot open it. I found that even newest version v.8.4.1 cannot be installed with OX 10.10.3. My MacBook Pro and iMac have Yosemite, therefore do I need to wait for a newer version of IDL before I can use IDl on these machines I wanted to install v.8.1 so that I will be able to use it without update.

2-vertex polyline drawn on image function graphic cannot be translated or rotated 1813 1
Started by Deleted User
Problem:
After drawing a 2-vertex polyline into the data space (/data) of a image graphic:
img = image( dist(400,400) )
p2 =polyline(&91100,300&93, &91100,300&93, '-r2', /data, target=img)
I'm unable to translate or rotate the polyline without changing its shape or slope. That is, I'm only able to individually move around the ends of the polyline relative to the image graphic.

FILE_TEST function behavior 1756 1
Started by Zachary Norman
I found that function File_Test(file, /DIRECTORY) changes the modification date/time of the folder being tested in IDL 8.2. If I understand correctly, this function (with DIR keyword) is supposed to just tell me if the file is a directory, not to do anything to that file. But now every time I test a folder, its original modification time is changed by IDL to the current time. I didn't see this issue in IDL 7.1. Is it a new bug in 8.2 or is there any keyword or workaround that can keep this from ...
