您可以使用Windows Imaging Component加载PNG文件（在Windows XP SP2及更高版本上）。请参阅MSDN Magazine（原始版本为web archive-格式稍好一些），了解如何使用API和my blog post，了解如何从IStream加载PNG并将其转换为HBITMAP的代码示例。

不需要使用Windows Imaging Component、GDI+或PNG库。您可以使用图标功能。
1.添加新图标（ICO_PNG）到VC项目资源中，并自定义宽度和高度（资源编辑器->图像->新图像类型）。复制您的png图像在这里，并使用填充工具+透明颜色，使图标透明。
1.将图片控件（IDC_PNG）添加到您的对话框（类型=所有者绘制）。
1.对话程序代码：

switch (msg)
{
    ...

    case WM_DRAWITEM:
    {
        LPDRAWITEMSTRUCT pDIS = (LPDRAWITEMSTRUCT)lParam;
        if (pDIS->CtlID == IDC_PNG)
        {
            HICON hIcon = (HICON)LoadImage(GetModuleHandle(0), MAKEINTRESOURCE(ICO_LOGO), IMAGE_ICON, 0, 0, LR_LOADTRANSPARENT); 
            DrawIconEx(pDIS->hDC, 0, 0, hIcon, 0, 0, 0, NULL, DI_NORMAL);
            DestroyIcon(hIcon);
            return TRUE;
        }
    }
}

您可以使用StretchDIBits API来实现，但受操作系统/驱动程序可用性的限制。
有关详细信息，请参阅MSDN文档：
http://msdn.microsoft.com/en-us/library/dd145121(v=VS.85).aspx
http://msdn.microsoft.com/en-us/library/dd145107(VS.85).aspx
我真诚地道歉，误导了你们对这个问题感兴趣的人。让我纠正我的错误。PNG绘图没有StretchDIBits。您最好尝试WIC方法或考虑在您的项目中集成GDI+的方法。

我们可以通过GDI显示png图像，在创建窗口时通过以下两个步骤（窗口过程函数中的case WM_CREATE）：
1.加载png文件（通过libpng或stb image），像素值保存在变量中，比如buffer
1.在CreateBitmap()函数中使用buffer创建HBITMAP示例
下面是可运行的代码，它是纯C语言编写的，main()作为入口点函数（libpng和zlib来自我自己的opencv编译）

#include <stdio.h>
#include <windows.h>
#include "png.h"

#define CRTDBG_MAP_ALLOC 
#include <crtdbg.h>

// **NB**: You may use OpenCV prebuilt package's self contained libpng.lib file
// or, maybe, you can also compile it from source (which cost time and not necessary), see: `http://www.libpng.org` and  `https://www.zlib.net`

弗拉基米尔_hr的答案是简单本身。
简单的步骤遵循。
在resources头文件中声明如下：#define IDI_PNG 1000
在资源文件 *.rc中有：IDI_PNG ICON“protractor.ico”
图标文件。使用支持自定义大小而不是标准Windows图标大小的图标编辑器将您的（透明）png文件转换为图标文件，将此png图像保存为图标图像。
剩下的就是DC之间的传输了。
