25 The libtiff software was written by Sam Leffler while working for |
|
26 Silicon Graphics.<p> |
|

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