I've often wondered about this. Perhaps a more direct question is, do I get the same results making a font for a 600dpi device as I do making a 300dpi font at mag=2? (In particular, does the rounding happen the same way?) Presumably, the values of blacker, fillin etc in the 600dpi mode_def would have to be twice those in the 300dpi mode_def? (Aside: they are undimensioned units---blacker=.55, for example---so presumably are in numbers of pixels?) Is the question `Do I get the same results using mag as I do by multiplying all the dimensions directly by that amount?' equivalent? The Sauter scripts do the latter for the fonts which are interpolated from only one master (eg cmssq); is a 16pt cmssq (formed by multiplying all the dimensions in cmssq8 by 2) the same as cmssq8 scaled 2000? If so, what did Karl Berry mean when he wrote > I've > looked at some of the fonts, and they're pretty good. > (Better than the magnified versions!) (in the file READ_ME.unix with the Sauter scripts)? Did he just mean that a cmr14 interpolated from cmr12 and cmr17 was better than either one scaled? (Karl, are you reading this?)
