15 | Silicon Graphics has seen fit to allow us to give this work away. It | |
16 | is free. There is no support or guarantee of any sort as to its | |
17 | operations, correctness, or whatever. If you do anything useful with | |
18 | all or parts of it you need to honor the copyright notices. It would | |
19 | also be nice to be acknowledged.<p> | |

25 | The libtiff software was written by Sam Leffler while working for | |
26 | Silicon Graphics.<p> | |
27 | ||
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: | |
