That's a contradiction in terms.

If the file is just raw bytes without any header (or structure), then it is
not a TIFF file.
TIFF can include a raw, uncompressed byte dump - but it must have a header
and normal TIFF structure.

No,  they are raw uncompressed 16 bit tiff files without a header.  I
received a suggestion on using the ChannelInputStream class so I am going to
give this a try.

Are these RAW files from a digital camera?  If so, LibTIFF won't be able to
do much with them --  because RAW files are not simple pixels, they are a
record of the sensor data and need to be demosaic'd before they become
useful images.  Take a look at dcraw.

Has anyone used libtiff to read in a .raw file?  The files I have are raw,
uncompressed tiff images (16 bit).  I would like to read them in, write a
header and create a tiff file of them.
