sigh! i was expecting that question. lpi is quite different from ppi, which is quite different from dpi. dpi is *not* ppi. ppi is *not* lpi. lpi is *not* dpi. all three are different terms. the concepts are too fundamental. because of the confusion of these terms, things get royally screwed in production environment. imho, the next time you see a scanner specification that states the resolution in dpi, drop your pants, sit on the scanner, press the scan button, and save the image at the maximum resolution as "myass.jpg" :-) there are various fundamental mathematical equations that equate these terms, but the topic is too vast and dense to explain here. :-) LL _______________________________________________ ilugd mailing list [EMAIL PROTECTED] http://frodo.hserus.net/mailman/listinfo/ilugd
