I received some TIFF files generated by Agfa's PrintDrive software which use the undocumented value of 514 for the compression tag. The files also include private tags 44884, 44885 and 44900.

Does anyone on the list know more about these files?

They'll illegal - that doesn't appear to be a registered compression code or in the user defined range.

It could be corrupt, or it could be yet another case of someone writing TIFF without bothering to read the spec.
