# Contributed TIFF Software

The contrib directory has contributed software that uses the TIFF library or which is associated with the library (typically glue and guidance for ports to non-UNIX platforms, or tools that aren't directly TIFF related).

contrib/vms | scripts and files from Karsten Spang for building the library and tools under VMS
contrib/dbs | various tools from Dan & Chris Sears, including a simple X-based viewer
contrib/ras | two programs by Patrick Naughton for converting between Sun rasterfile format and TIFF (these require `libpixrect.a`, as opposed to the one in tools that doesn't)
contrib/mac-mpw contrib/mac-cw | scripts and files from Niles Ritter for building the library and tools under Macintosh/MPW C and code warrior.
contrib/acorn | scripts and files from Peter Greenham for building the library and tools on an Acorn RISC OS system.
contrib/win32 | scripts and files from Scott Wagner for building the library under Windows NT and Windows 95. (The makefile.vc in the libtiff/libtiff directory may be sufficient for most users.)
contrib/win_dib | two separate implementations of TIFF to DIB code suitable for any Win32 platform. Contributed by Mark James, and Philippe Tenenhaus.
contrib/ojpeg | Patch for IJG JPEG library related to support for some Old JPEG in TIFF files. Contributed by Scott Marovich.
contrib/dosdjgpp | scripts and files from Alexander Lehmann for building the library under MSDOS with the DJGPP v2 compiler.
contrib/tags | scripts and files from Niles Ritter for adding private tag support at runtime, without changing libtiff.
contrib/mfs | code from Mike Johnson to read+write images in memory without modifying the library
contrib/pds | various routines from Conrad Poelman; a TIFF image iterator and code to support ``private sub-directories''
contrib/iptcutil | A utility by Bill Radcliffe to convert an extracted IPTC Newsphoto caption from a binary blob to ASCII text, and vice versa. IPTC binary blobs can be extracted from images via the ImageMagick convert(1) utility.
contrib/addtiffo | A utility (and supporting subroutine) for building one or more reduce resolution overviews to an existing TIFF file. Supplied by Frank Warmerdam.
contrib/stream | A class (TiffStream) for accessing TIFF files through a C++ stream interface. Supplied by Avi Bleiweiss.

Questions regarding these packages are usually best directed toward their authors.
