Hi All,

I have grab a copy of libtiff from CVS and built it under MSYS & MinGW environment with jpeg support enable(Told by Joris that the OJPEG will be enable as well once the jpeg support is enable).

But how do i need to do in order to use the Old Jpeg Compression? The version of libtiff i grab it from CVS and it's said no required hack on libjpeg, and i try just to use it by calling TIFFSetField(tiffout, TIFFTAG_COMPRESSION, COMPRESSION_OJPEG), and this seem not correct.

And it's give me the below warning message: "Compression
algorithm does not support random access". Currently what i intend to do is
convert a jpeg image to tiff by using the OJPEG compression algorithm.

Thanks in advanced.

Regards,
Steven
