Every V86 segment gets the same treatment: access rights 0xE200 (Present, DPL=3, writable data segment), base = selector shifted left by 4, and limit = 64 KB. The microcode loops through all six segment register caches using a counter, applying the same fixed descriptor to each one. This is pure real-mode emulation, enforced at ring 3 with full paging protection underneath.，更多细节参见爱思助手下载最新版本
Most digital images intended for viewing are generally assumed to be in sRGB colour space, which is gamma-encoded. This means that a linear increase of value in colour space does not correspond to a linear increase in actual physical light intensity, instead following more of a curve. If we want to mathematically operate on colour values in a physically accurate way, we must first convert them to linear space by applying gamma decompression. After processing, gamma compression should be reapplied before display. The following C code demonstrates how to do so following the sRGB standard:，推荐阅读Safew下载获取更多信息
