What point means is how large a typeface is in print. Points and picas are absolute measurements like inches. An inch is an inch. A point is a point. When translated to computer screens the pixel size and density (ppi) does matter because 100 pixels on one screen is not the same absolute dimensions as 100 pixels on a different screen. Most contemporary desktop environments have mechanisms for scaling so that a 1 inch line is 1 inch regardless of the display's ppi -- but most also default to 96ppi which means you get the behavior I described. Which brings me back to the point I made about screen size: you have to upscale everything on a UHD screen in order to make everything appear to be the same size as it would appear on a 1080p screen with the same dimensions. Which is to say, the 4 times greater resolution of UHD is wasted if you need to make everything 4 times larger in order to achieve consistency. Or you can use a physically larger display. A UHD display needs to be about 4 times larger (twice as wide, twice as tall) as a 1080p display to achieve identical (or close enough) absolute sizes of displayed objects without scaling. If you are comfortable with a 17" display at 1080p then you will need a 35" UHD display to achieve a similar level of comfort without scaling. -- Rich P. _______________________________________________ Discuss mailing list [email protected] http://lists.blu.org/mailman/listinfo/discuss
