windows-8 – 如何使用在任何分辨率上都很好的字体设计Metro UI

For those who buy these higher pixel-density screens,we want to ensure that their apps,text,and images will look both beautiful and usable on these devices. Early on,we explored continuous scaling to the pixel density,which would maintain the size of an object in inches,but we found that most apps use bitmap images,which could look blurry when scaled up or down to an unpredictable size. Instead,Windows 8 uses predictable scale percentages to ensure that Windows will look great on these devices. There are three scale percentages in Windows 8:

100% when no scaling is applied
140% for HD tablets
180% for quad-XGA tablets

The percentages are optimized for real devices in the ecosystem. 140% and 180% may seem like odd scale percentage choices,but they make sense when you think about how this will work on real hardware.

For example,the 140% scale is optimized for 1920×1080 HD tablets,which has 140% of the baseline tablet resolution of 1366×768. These optimized scale factors maintain consistent layouts between the baseline tablet and the HD tablet,because the effective resolution is the same on the two devices. Each scale percentage was chosen to ensure that a layout that was designed for 100% 1366×768 tablets has content that is the same physical size and the same layout on 140% HD tablets or 180% quad-XGA tablets.
