Remarks
A DevWare plug-in implementing the LinearImageData() hook can process the image here. If there was no multiple exposure combining, then this data is the same as the RawImageData() hook. The image format can't be changed.

Remarks
Subtract black pedestal and rescale pixel data to 0…4095. (If raw data is less then 12 bits, then scale up to 12 bits. If raw data is more than 12 bits, then just use 12 of the bits and discard the rest, usually the 12 MSBs.) For all subsequent blocks, Bayer data is 12 bits with no pedestal.

There are a couple of ways of processing an image without an actual device being attached;
- If you have a raw image file you want to run through the colorpipe:
ap_CreateFromImageFile()
ap_GrabFrame()
ap_ColorPipe() - If you have image data in memory imitating the output of a sensor:
ap_CreateVirtual(path_to_sensor_xsdat_file)
ap_SetImageFormat()
ap_ColorPipe()
