是否存在stb_image simd支持？
[英]Does stb_image simd support exist?
问题描述
stb_image appears to have support for plug-in SIMD implementation(s) of the idct and ycbcr->rgb conversion operations, which take majority of time when loading jpeg files. 
stb_image似乎支持idct和ycbcr-> rgb转换操作的插件SIMD实现，这些操作在加载jpeg文件时占用大部分时间。 Looking at the code behind STBI_SIMD it's pretty clear this code has actually been used somewhere. 看看STBI_SIMD背后的代码，很明显这个代码实际上已在某处使用过。
However, either the implementations have been proprietary, or my google-fu fails me, as I haven't found any public code that uses this interface. 但是，要么实现是专有的，要么我的google-fu失败了，因为我还没有找到任何使用此接口的公共代码。
My needs would be for the x86 platform only (at this time). 我的需求只适用于x86平台（此时）。
Is there any open source that uses this interface? 是否有任何开源使用此接口？

I remember seeing your question on Twitter, where today coincidently someone mentioned libjpeg-turbo licensed under the BSD license. 我记得在Twitter上看过你的问题，今天恰巧有人提到了根据BSD许可证获得许可的libjpeg-turbo 。 Hope that helps. 希望有所帮助。

although I was expecting SSE, SIMD at its purest.. 虽然我期待SSE，SIMD最纯粹。
