Create my own custom coder

[efficks]

Hi,
I need to create my own custom coder.
I looked some examples in the coders directory and I also check the coder kit. Where can I find some information on what is in the image info class, the image class. What I need to set on the image class. All the doc on what values are setted and which one I need to set.
I'm creating a coder for raw data encoded in 8,10 and 12 bits with or without a proxy. This data is extracted by connecting to a server and reading the data from there.
Finally, these data represents a video. So each clip is a frame of the video. Can I specify this to image magick and ask how many frame I'm reading, which frame number etc.

Thank you for your help.
