Libtiff should also support 12 bits using 6b libjpeg if possible. I believe that the interface is compatible since it looks like the "Mk1" interface.
Bob,
Yes, it is my hope to do a test build this way and verify that things work properly. As far as I can tell the current tif_jpeg.c does not repack the 16bit values returned by libjpeg6b (in 12bitmode) to 12bit. Folks have apparently used this form, but I don't really know how they make it work.
Best regards,
