Unless I have missed something, I think it should be possible to include its support in libtiff, else libjpeg style approach can ofcourse be used. (I am not a lawyer)

Sachin,

I can't say that I have a good understanding of the HD Photo format. It seems to use TIFF style directories, but to maintain it's own complete set of baseline tags, making it... not TIFF at all really.

I'd suggest you experiment with support for it either in a working fork of libtiff or in something that can be layered on libtiff (in the way that geotiff is) for now. Perhaps when we see what a minimum-disruption approach to supporting HD Photo would look like, we (the libtiff maintainers) would be more comfortable with it's incorporation in the core.

Though I haven't dug deep, on the face of it I'm very offended that Microsoft has chosen to "do it's own thing" without regard to existing standards. Like Andrey, I don't feel inclined to bend over backward to make up for their offense.

Nevertheless, if you can be patient, perhaps you can bring us around and we can end up with a libtiff that supports their format smoothly, at least for reading.

Best regards,
--
