I wrote a bolg to complain no descriptions for ENVI APIs on 26^th, November, resulting difficulty in invoking ENVI Routines. Later, I was proposed to go through ENVI Help, but, which had been checked for a long time, google also. Some useful APIs are remaining blind to us, of course, some examples will show the arguments relate to its routines, but I think they are not enough to comprehend and employ. I have an idea to consult Exelis directly, when I discuss with other.

And a letter was sent to Exelis yesterday, a reply has been received this noon. Please see the following:

For some unknown reasons, Exelis would not like to distribute Introductions for these procedures. So, we should do it by myself.
