I see... sort of.

I understand that once I have a IWICBitmapEncoderInfo, I simply call
IWICBitmapEncoderInfo_CreateInstance(bitmapencoderinfo, &bitmapencoder).

However, I am a little unclear on the CoCreateInstance part.

For example, for the imaging factory, I use:
CoCreateInstance(&CLSID_WICImagingFactory, NULL, CLSCTX_INPROC_SERVER,
&IID_IWICImagingFactory, (void**)&factory);
to create the instance.

If I have a GUID, such as GUID_ContainerFormatBmp, how do I use
CoCreateInstance to create an instance of the appropriate
IWICBitmapEncoderInfo? Is this then the CLSID? For example:
CoCreateInstance(&GUID_ContainerFormatBmp, NULL, CLSCTX_INPROC_SERVER,
&IID_IWICBitmapEncoderInfo, (void**)&bitmapencoderinfo);

Also, would this not work then?
CoCreateInstance(&GUID_ContainerFormatBmp, NULL, CLSCTX_INPROC_SERVER,
&IID_IWICBitmapEncoder, (void**)&bitmapencoderinfo);
and save the call to IWICBitmapEncoderInfo_CreateInstance?

I don't mean to sound naive... but I learn on the fly.

Thank you
