aiya!! i knew this would happen. i should have kept my mouth shut. changing the dpi does not mean interpolating like you suggest. changing the dpi means absolutely no change in the info content of the image. example: 1280x960 @ 72dpi to 640x480 @ 144 dpi....no interpolation involved. Let's be clear, Vue allows you to set ANY dimension for your rendering, it just doesn't let you adjust the dpi of the image. And also, to be perfectly correct, we should be using ppi (pixels per inch) and not dpi (a printer feature). and setting the ppi to something different than 72 ppi, is simply an "instruction" for the printer to size the image a certain way....to print "so many pixels within the length of an inch". and you have to open some sort of program to print your image anyway, therefore, my conclusion that being able to preset the ppi would mean only the smallest saving in time. Interpolation would occur if we changed 1280x960 @ 72 ppi to 1280x960 @ 144 ppi. But this is *2* operations, change the ppi and resize (where the interpolation occurs). phew.....
