--- Start of Idrisi List message When I use scanned image maps I always save them as 8-bit (You lose some colors). Then you can import and resample them with no problems. //H�lsningar / Regards Gustaf Svedjemo ~~~~~~~~~~~~~~~~~~~~~ H�gskolan p� Gotland / Gotland University College Cram�rgatan 3 S-621 57 Visby Sweden E-post / Email: [EMAIL PROTECTED] Tel / Phone: +46 (0)498 29 98 86 Fax: +46 (0)498 29 98 32 Mobil / Cell: +46 (0)708 858 126 WWW: http://www.hgo.se ~~~~~~~~~~~~~~~~~~~~ > -----Ursprungligt meddelande----- > Fr�n: Graham Gow [SMTP:[EMAIL PROTECTED]] > Skickat: den 6 september 2000 08:51 > Till: [EMAIL PROTECTED] > �mne: Idrisi-L : RGB24 data type and RESAMPLE > > --- Start of Idrisi List message > Hi all. > > I have managed to get IDRISI to display a scanned image of a paper map (as > you may have noted from my earlier postings!).
