C++ (Cpp) GetImageDecodeIID Examples

Example #1

File: il_wdp.c Project: 123woodman/minko

ERR ilPKCodecFactory_CreateDecoderFromFile(PKImageDecode** ppDecoder)
{
    ERR err = WMP_errSuccess;

    char *pExt = ".wdp";  // We are loading a WDP file, so we have to tell the library that with this extension.
    PKIID* pIID = NULL;

    struct WMPStream* pStream = NULL;
    PKImageDecode* pDecoder = NULL;

    // get decode PKIID
    Call(GetImageDecodeIID(pExt, &pIID));

    // create stream
    Call(ilCreateWS_File(&pStream, NULL, "rb"));

    // Create decoder
    Call(PKCodecFactory_CreateCodec(pIID, ppDecoder));
    pDecoder = *ppDecoder;

    // attach stream to decoder
    Call(pDecoder->Initialize(pDecoder, pStream));
    pDecoder->fStreamOwner = !0;

Cleanup:
    return err;
}
