--- Start of Idrisi List message Hi! Does anyone know how colour bitmaps are converted to idrisis byte format with values from 0 to 255? If I have a colour photo and import it to idrisi with BMPIDRIS, what values do I have in the resulting image? Do the values represent dark to light shades (how in that case) or are the colours somhow separated? For instance, does a 100% red pixel get the same idrisi value as a 100% green pixel? Maybe I need to go even further back to how my original image was created and stored? Any ideas are welcome! Marie Eriksson --- End of Idrisi List message IDRISI-L is an unmoderated list.
