/* tiff loading for GIMP
|
|
* -Peter Mattis
|
|
*
|
|
* The TIFF loading code has been completely revamped by Nick Lamb
|
|
* njl195@zepler.org.uk -- 18 May 1998
|
|
* And it now gains support for tiles (and doubtless a zillion bugs)
|
|
* njl195@zepler.org.uk -- 12 June 1999
|
|
* LZW patent fuss continues :(
|
|
* njl195@zepler.org.uk -- 20 April 2000
|
|
* The code for this filter is based on "tifftopnm" and "pnmtotiff",
|
|
* 2 programs that are a part of the netpbm package.
|
|
* khk@khk.net -- 13 May 2000
|
|
* Added support for ICCPROFILE tiff tag. If this tag is present in a
|
|
* TIFF file, then a parasite is created and vice versa.
|
|
* peter@kirchgessner.net -- 29 Oct 2002
|
|
* Progress bar only when run interactive
|
|
* Added support for layer offsets - pablo.dangelo@web.de -- 7 Jan 2004
|
|
* Honor EXTRASAMPLES tag while loading images with alphachannel
|
|
* pablo.dangelo@web.de -- 16 Jan 2004
