windows 使用 Win32/C++ 读取 PNG

Read a PNG Using Win32 / C++

提问by I. J. Kennedy

That there is no simpleway to read a PNG file into a memory bitmap in native Windows seemed impossible, but after much googling I'm beginning to believe it. The libpng/zlib combination is just too big. Any third-party libraries Win32 libraries out there for reading a PNG?

在本机 Windows 中没有简单的方法将 PNG 文件读入内存位图似乎是不可能的，但经过多次谷歌搜索后，我开始相信它。libpng/zlib 组合太大了。任何用于读取 PNG 的第三方库 Win32 库？

Edit: The boost::gil::png solution is much more complex than I'd hoped, too. Just need a single call that takes a file name and fills a memory buffer with pixels.

编辑： boost::gil::png 解决方案也比我希望的要复杂得多。只需要一次调用即可获取文件名并用像素填充内存缓冲区。

Or of course you could use GDI+ - The Bitmapobject takes a string constructor and loads the specified file into memory. That way you don't need any external libraries, just that which comes with windows.

或者当然您可以使用 GDI+ - Bitmap对象采用字符串构造函数并将指定的文件加载到内存中。这样你就不需要任何外部库，只需要 Windows 自带的库。

There is some built-in stuff you can use: IImgCtxand on later versions of windows you also have WIC

你可以使用一些内置的东西：IImgCtx和更高版本的 Windows 你也有WIC
