  • Question

  • I've tried this code with VS2012 but I can't resolve the WIC references. What header files do I need?

    IWICImagingFactory *pFactory = NULL;
    IWICBitmapDecoder *pDecoder = NULL;

    HRESULT hr = CoCreateInstance



    if (SUCCEEDED(hr))
      hr = pFactory->CreateDecoderFromFilename

  • You can find the required header files at the bottom of the interface documentation:


    Header: Wincodec.h

  • Thanks. Now I just get the following after adding wincodec.h:

    error LNK2001: unresolved external symbol _IID_IWICImagingFactory

  • Are you linking to Windowscodecs.lib? The required library is mentioned two lines down from the header in the interface docs.

  • BTW, Windowscodecs.lib is not available for ARM builds, as in it won't run on Tablets, kinda weird...

  • WIC is supported by Windows 8 and Windows RT. As such, windowscodecs.lib is present as noted by Rob in the Windows 8.0 SDK.

    NOTE: WIC is not supported by Windows phone 8.

  • Yes, I'm using WIC on ARM with C# but i need c++ Sinkwriter. It seems to be supported with SharpDX but I can't find any same code. I need WIC to inject photos from disk into video.
