Different numerical results between IDL6 and IDL7 1725 0
Started by Deleted User
Hello,
I have a program that was written in IDL6.&160; I'm currently running it in IDL7 and have noticed that the numerical calculations are not the same between the two.&160; Certain numbers differ by ~0.02.&160; While this is not much, it matters for my application.&160; Has anybody observed this before and if so, is there a fix&160; Thanks, Mike Runkel

question about query_tiff for large file 1444 0
Started by Deleted User
query_tiff is working rather slow with my big files. Maybe my files are indeed too big, ~10k frames. Even query_tiff(filename,image_index=0) would take several minutes.
On the other hand, I found read_tiff works quite differently in term of speed. If I have this big tiff stack here and want IDL to know the number of frames, is there any fast way Do I need to know something deep about the tiff file format, head codes or the like
thanks

Misalignment between image map and contours 1399 0
Started by Deleted User
I was trying to display an image and superpose its contours, and noticed that there seems to be a misalignment, or better a scale factor difference, between the contours and the image map.
This problem can be seen in a very simple way by using the image_cont routine, for example:
a=0*findgen(16,16)
a&911,1&93=1000
a&9112,12&93=1000
a&918,8&93=1000
a&913,14&93=1000

The center of the contour maps are offset with respect to the corresponding pixel. A more careful...

Poor User Support from ITT 1548 1

Has anybody else using ENVI/IDL experienced poor support from itt. I have been using this (quite expensive) product for 8 years now and none of the bugs (some quite serious) have ever been addressed. These range from supposed support for reading ER Mapper files (none of the geo-referencing information is imported forcing me to input it manually) to extremely serious issues such as the fact that LSFIT procedures include missing value codes in the computations thus producing totally erroneous ...
