WIC Codec fail in Vista And Window 7 OS

Question

Hi Experts,
                  I developed a WIC codec that support a new image format suppose XYZ format(codec named ,XYZ Encoder) which can encode an image in to XYZ format and image created in such format can get open succesfully in WIC explorer.

But when I tried to test my codec on Vista or Window 7 machine. It doesn't work . As I try to convert an image in to XYZ format in Vista machine using WIC explorer, WIC explorer doesn't find any such encoder named XYZ Encoder in their available encoder list. My codec is woking fine in XP machine. If anybody faced the similar kinda problem, then please help me in this regard.

Thanks & Regards
Vicky

Hi Experts

              I would like to ask the WIC community only one question. Is there anybody who work on Vista or Window 7 OS and faced the same kind of problem what I am facing now?

I am succesful to developed a new image format named xyz that can work in Window XP, but why the same codec creating problem in Vista or Window 7 OS? This is the biggest worry, Why WIC explorer doesn't find my XYZ encoder in its available encoder list.

Please if anybody work on the same kind of problem earlier, then please help me .

Thanks & Regards
Vicky

Hi

I'm not a expert ;), but I'm trying to dicover more functionality based on WIC and I find some diffirence beetween Vista and Windows 7. In general it looks like that GUIDs regarding main components (like WIC Encoders and WIC decoders), change a little.You must register you encoder under other GUID. Currently I dont have more details about that but I'm trying to go deeper. When I will have more information I will post it.

hi
    Thax alot Slawek...


I am not seeing any entry in the registry with respect to my Encoder in Vista or Window 7 machine. That why I guess my encoder is not shown in available encoder list of WIC explorer in Vista and Window 7. But its registry entry created once you digitally signing the dll in Xp. Mean as soon as I digitally signed the dll in XP machine, it created the registry entry with respect to my encoder.So you can say because of registry entries doesn't created in Vista and Window7, was the main reason for failure on those OS. I don't know how to resolve it, if you can find anyway that can help me in successfully running  the WIC codec on those(Vista and Window 7) OS, then I am really thankful to you.
