pixel art之 hqx 算法
2018-06-17 23:54:14来源：未知 阅读 ()
在去年的时候，偶然看到hqx算法。
一个高质量的插值放大算法。
与双线性插值等插值算法相比，这个算法放大后对人眼保护相对比较好。
没有双线性插值看起来模糊，固然，也抽空把算法简单优化了一下。
官网及代码：

不够这个算法写得贼恶心，并不适用于学习。
贴上维基百科上的demo效果对比图。
博主只是简单地把其中的放大两倍的算法，优化了一下，极大地提升算法的速度。
废话不多说，贴上代码：

本代码仅支持4通道32位，若1通道以及3通道，可参考改动之。
也不是很麻烦，代码也是挺简单的，虽然有点长，懒得写注释了，感兴趣的可以看看官方的代码。
俺这代码主要是做了一些算法上的简单优化。
好久没发博文里，上来冒个泡。不喜请喷。
