Dear ENVIans, The "Output ROIs to ASCII" command format files in the following manner: ;ENVI Output of ROIs (3.4) [Mon Apr 17 17:00:26 2000] ... ; ID X Y B1 B2 B3 1 12 14 255 0 124 2 13 28 153 100 ... where X and Y are sample and line numbers, and B1, B2, b3 give the DN corresponding to some spectral band. I have already Outputted ROIs data to ASCII. Now I would like to re-import my data and create an image corresponding to a particular field. Is there a build-in function that could do the job ? An IDL macro (function) ? If no, how would you do it ? Best regards, Philippe Apparicio
