Sorry, as I was waiting for the bus home yesterday it occurred to me that I had written something wrong... I should probably be more careful with arithmetic so late in the afternoon :) Not sure where the 1/128 came from, it should of course be 1/192 (half of 1/96). Though 312/192 = 1.625 still rounds to 2, and with Kenneth's percentages it would as well (60% would give 1.95 and 70% would give 2.275). > Thanks for the clarification. Is there an online calculator that gives > the optimal size of a pixel (or the DPI) given the viewing distance? Not that I know, but it's basically just a linear relationship with a 1/96 inch pixel size at 28 inches viewing distance, as indicated by other posts. -- Øyvind Stenhaug Opera Software ASAReceived on Tuesday, 29 January 2013 11:14:46 UTC
