Pocket中使用IImage

頭文件的包含順序很重要 

#include <initguid.h>

#include <imaging.h>

其中<initguid.h>一定要在<imaging.h>之前，否則會出現錯誤，然後實例代碼入下

    IImagingFactory *pImgFactory = NULL;

    IImage *pImage = NULL;

    RECT rc = { 0, 0, 110, 88};

    // Normally you would only call CoInitialize/CoUninitialize

    // once per thread.  This sample calls CoInitialize in this

    // draw function simply to illustrate that you must call 

    // CoInitialize before calling CoCreateInstance.

    CoInitializeEx(NULL, COINIT_MULTITHREADED);

    // Create the imaging factory.

    if (SUCCEEDED(CoCreateInstance (CLSID_ImagingFactory,

                                    NULL,

                                    CLSCTX_INPROC_SERVER,

                                    IID_IImagingFactory,

                                    (void **)&pImgFactory)))

    {

        // Load the image from the JPG file.

        if (SUCCEEDED(pImgFactory->CreateImageFromFile(

                        TEXT("//Program Files//Imaging//flower.jpg"),

                        &pImage)))

        {

            // Draw the image.

            pImage->Draw(hdc, &rc, NULL);

            pImage->Release();

        }

        pImgFactory->Release();

    }

    CoUninitialize();
