I want to integrate my image decoder for *.xyz to my gecko-based application so that when the application load a web page with <img src="a.xyz">, the image could be correctly shown in layout.
What should I do? I am reading the code about how gif is decoded in Mozilla code. But it is hard to understand the logic there.
So far I build an xp component. My application loads the component successfully when the application starts up. I register the content-type "image/xyz" as by
rv = catman->AddCategoryEntry("Gecko-Content-Viewers", "image/xyz", XYZ_ContractID, PR_TRUE, PR_TRUE, &previous);
What should my next move be?
How to let gecko call my decoder?
How to return the decoded raw image back to layout engine to show?

Adding your component to the "Gecko-content-viewers" category is definitely wrong. To implement a image decoder, all you need to do is implement the imgIDecoder interface, and then register your component under the ContractID: "@mozilla.org/image/decoder;2?type=image/x-foo", where "image/x-foo" is the MIME type you wish to handle.
See: http://lxr.mozilla.org/mozilla/source/modules/libpr0n/public/imgIDecoder.idl
NOTE: imgIDecoder is not a frozen interface, so your component may not work with future versions of Mozilla (or Firefox).
