Question

I’m trying to load a ID2D1Bitmap from a bitmap resource. To do so, I consulted an MSDN guide which told me to use the Windows Imaging Component (IWIC) to process the image before Direct2D uses it.

However, it fails when I call CreateDecoderFromStream(), and it returns a strange error message – 0x88982f50 – that tells me nothing. I’ve searched Google and used DirectX Error Lookup. The DirectX Error Lookup tool only tells me this:

HRESULT: 0x88982f50 (2291674960)
Name: Unknown
Description: n/a
Severity code: Failed
Facility Code: FACILITY_DWRITE (2200)
Error Code: 0x2f50 (12112)

This is the code I’m using to try and load an ID2D1Bitmap from a resource:

int LoadBitmapFromResource( IWICImagingFactory *pIWICFactory, ID2D1RenderTarget *pRT, int resID, ID2D1Bitmap **ppD2DBitmap )
{
    int errmsg;

    HRSRC hbmp;
    HGLOBAL hbmpdata;
    void *pbmp; //system memory pointer to bitmap resource
    DWORD bmpsize;
    IWICStream *pStream;
    IWICBitmapDecoder *pbmpdecoder;
    IWICBitmapFrameDecode *pSource;
    IWICFormatConverter *pConverter;

    hbmp = FindResourceW( GetModuleHandleW(NULL), MAKEINTRESOURCEW(resID), RT_BITMAP );
    if( NULL == hbmp )
    {
        printf("LoadBitmapFromResource::FindResourceW() error: %d\r\n", GetLastError() );
        return GetLastError();
    }

    hbmpdata = LoadResource( GetModuleHandleW(NULL), hbmp );
    if( NULL == hbmpdata )
    {
        printf("LoadBitmapFromResource::LoadResource() error: %d\r\n", GetLastError() );
        return GetLastError();
    }

    pbmp = LockResource( hbmpdata );
    if( NULL == pbmp )
    {
        printf("LoadBitmapFromResource::LockResource() error: %d\r\n", GetLastError() );
        return GetLastError();
    }

    bmpsize = SizeofResource( GetModuleHandleW(NULL), hbmp );
    if( NULL == bmpsize )
    {
        printf("LoadBitmapFromResource::SizeofResource() error: %d\r\n", GetLastError() );
        return GetLastError();
    }

    errmsg = pIWICFactory->CreateStream( &pStream );
    if( !SUCCEEDED(errmsg) )
    {
        printf("LoadBitmapFromResource::CreateStream() error: %x\r\n", errmsg );
        return errmsg;
    }

    errmsg = pStream->InitializeFromMemory( (BYTE*)pbmp, bmpsize );
    if( !SUCCEEDED(errmsg) )
    {
        printf("LoadBitmapFromResource::InitializeFromMemory() error: %x\r\n", errmsg );
        return errmsg;
    }

    errmsg = pIWICFactory->CreateDecoderFromStream( pStream, NULL, WICDecodeMetadataCacheOnLoad, &pbmpdecoder );
    if( !SUCCEEDED(errmsg) )
    {
        printf("LoadBitmapFromResource::CreateDecoderFromStream() error: %x\r\n", errmsg );
        return errmsg;
    }

    errmsg = pbmpdecoder->GetFrame( 0, &pSource );
    if( !SUCCEEDED(errmsg) )
    {
        printf("LoadBitmapFromResource::GetFrame() error: %x\r\n", errmsg );
        return errmsg;
    }

    errmsg = pIWICFactory->CreateFormatConverter( &pConverter );
    if( !SUCCEEDED(errmsg) )
    {
        printf("LoadBitmapFromResource::CreateFormatConverter() error: %x\r\n", errmsg );
        return errmsg;
    }

    errmsg = pConverter->Initialize( pSource, GUID_WICPixelFormat32bppPBGRA, WICBitmapDitherTypeNone, NULL, 0.0f, WICBitmapPaletteTypeMedianCut );
    if( !SUCCEEDED(errmsg) )
    {
        printf("LoadBitmapFromResource::Initialize() error: %x\r\n", errmsg );
        return errmsg;
    }

    errmsg = pRT->CreateBitmapFromWicBitmap( pConverter, ppD2DBitmap );
    if( !SUCCEEDED(errmsg) )
    {
        printf("LoadBitmapFromResource::CreateBitmapFromWicBitmap() error: %x\r\n", errmsg );
        return errmsg;
    }

    pConverter->Release();
    pSource->Release();
    pbmpdecoder->Release();
    pStream->Release();

    return 0;
}

It turns out I should not be using the WIC decoder for my bitmap resource, because it is apparently raw pixel data that cannot be decoded.
