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:
We can even go ahead and write a quick time-travel function like the one below to replay any execution trace locally, complete with built-in support for detecting time paradoxes!

第二，非正规经济。德索托的另一个重要贡献，是重新解释“非正规经济”。传统观点常把地下经济视为逃税、违法或缺乏公民意识的表现，但德索托指出，很多穷人并非不愿守法，而是制度成本过高。，详情可参考搜狗输入法下载
