+ +The LZW algorithm is derived from the compress program (the proper +attribution is included in the source code). The Group 3 fax stuff +originated as code from Jef Poskanzer, but has since been rewritten +several times. The latest version uses an algorithm from Frank +Cringle -- consult libtiff/mkg3states.c and +libtiff/tif_fax3.h for further information. +The JPEG support was written by Tom Lane and is dependent on the +excellent work of Tom Lane and the Independent JPEG Group (IJG) +who distribute their work under friendly licensing similar to this +software. +Many other people have by now helped with bug fixes and code; a +few of the more persistent contributors have been: + +
