Platform SDK Shell, How do I add an image format to IPreview?

Hello,

I am trying to rephrase my last question.

When calling the IPreview COM object, I can show a bunch of image format:
those known by Windows XP.

Surely, there is a way to implement my own image filter. How does one do
that? I want to do my own PNGFilt.DLL for other image formats.

Thanks

Jean-Michel

As I already mentioned, shimgvw is implemented using GDI+, which does not currently support custom codecs. A future version of GDI+ may support custom codecs, perhaps in time for Longhorn. (In fact, beta versions of 1.1 have been kicking around for ages but so far MS has refused to officially release it.)
