ENVI has the ability to write out ROI data to an ASCII file. The file
will contain some info on the image the ROI was created with (like the
image dimensions), and then a table with the coordinates of the pixels
in the ROI and their brightness values. If nothing else, you should
be able to create this kind of text file with C++ and have ENVI read
that back in, right?
