It will ignore instructions to display at (say) 72dpi simply because it can't do that. That's why if the file doesn't change the image size displayed on the screen remains constant as it is dependent only on the number of pixels to be displayed. which is why some computers are no longer using pixels for imaging. they're using points, which may be more than one pixel. this is because individual pixels can no longer be seen. Then why have smaller pixels? because then pixels are no longer a limitation. you can see pixelization on non-retina displays. you *can't* on a retina display. the difference is very noticeable, which is why companies are now making them. It is often possible to set up your monitor to display at a different resolution from the native pitch but it will be still using its native (say) 96 ppi. What it will be doing is resampling your image on the fly with a probably cheap and nasty (but fast) algorithm. This will result in the displayed image being inferior to the one you would see if it was displayed at the native resolution. not necessarily. try a retina display sometime. I bet it's possible to resample an image in a fashion which would make it appear to its disadvantage on a Retina display. sure, if you want to game the system and intentionally display crap, go for it. Nevertheless I accept that in most cases most people would be hard put to notice the difference. noticing the difference between retina & non-retina displays is not that hard, although many people don't notice it right away. they get a retina display and don't see much of a difference, then they go back to their older display and realize how crappy it really was. |

The one you were in reference to when you quoted me above. I just jumped in with a pejorative against your abysmal spelling, which means that reading your posts is more like decoding hieroglyphs than reading a coherent line of thinking. For you maybe but most people, well humans anyway, have abilities that mean they can decode such things, obviously beyond you it seems. Very few can decode hieroglyphs, Tipsy Dave. -- Sandman[.net] |

Actually the quoted figure of 72ppi is relevant to the older Apple displays. (It may still be relevant but I don't know that). The Microsoft standard was 1/3 greater - 96dpi - for the usual Microsoft reasons. it's was never relevant. It is true that the original Macintosh had a 72 ppi screen, but it isn't true that the "Microsoft standard" was 96 ppi, because Microsoft sold no displays (as far as I know. True, but they displayed their output on screens sold by other people. Micosoft designed their standard fonts around a hypothetical screen of 96ppi. I believe they may have now gone to 120ppi but I don't really know. A 17" screen with the resolution of 1280x1024 has a ppi of 96, but back when the 72/96 ppi myth started, there were no such high resolution screen, and when they were common, the original Macinosh was just a memory and the screens were as common for Macs as for PCs. You need to go down to a 13" screen at 1024x768 to get 96ppi again, but 13" desktop screens weren't very common (15" was the common step). 13" was more for laptops, and again, when people had laptops to start such a myth, the original Mac was again a memory. Many older CRTs used to have a pitch of 72dpi but towards the end they began creeping up. My present LCD has 92dpi. that's very low. Indeed, 92ppi is quite low. That's a 20" at 1600x900 or 24" at 1920x1080. I can't think of any other resolution that would match and be current. The latter. I once wrote a PPI calculator that I just remember: http://sandman.net/misc/ppi That's to calculate the PPI of your screen, or any screen. It doesn't have 24" screens. -- Regards, Eric Stevens |
