| 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
