It 16is free. There is no support or guarantee of any sort as to its 17operations, correctness, or whatever. If you do anything useful with 18all or parts of it you need to honor the copyright notices.

The Group 3 fax stuff 30originated as code from Jef Poskanzer, but has since been rewritten 31several times. The latest version uses an algorithm from Frank 32Cringle -- consult <TT>libtiff/mkg3states.c</TT> and 33<TT>libtiff/tif_fax3.h</TT> for further information. 34The JPEG support was written by Tom Lane and is dependent on the 35excellent work of Tom Lane and the Independent JPEG Group (IJG) 36who distribute their work under friendly licensing similar to this 37software. 38Many other people have by now helped with bug fixes and code; a 39few of the more persistent contributors have been: 40 41<PRE> 42 Bjorn P.
