TIFF CHANGE INFORMATION
This document describes the changes made to the software between the
previous and current versions (see above).
If you don't find something listed here, then it was not done in this
timeframe, or it was not considered important enough to be mentioned.
The following information is located here:
CHANGES IN THE SOFTWARE CONFIGURATION:
- support was added for configuring the Deflate codec
- support was added for the HTML documentation
- codecs that are not configured for inclusion in the library
are no longer compiled
CHANGES IN LIBTIFF:
- support was added for registering new codecs external to the library
and for overriding the codecs that are builtin to the library
- emulation support for the old DataType tag was improved
- suppport was added for the SMinSampleValue
and SMaxSampleValue tags
- the library no longer ignores TileWidth and TileLength
tags whose values are not a multiple of 16 (per the spec); this
permits old, improperly written, images to be read
- the support for the Predictor tag was placed in a reusable
module so that it can be shared by multiple codecs
- experimental compression support was added for the Deflate algorithm
(using the freely available zlib package)
- a new routine, TIFFWriteBufferSetup was added a la the
routine TIFFReadBufferSetup
- the DSO version of the library is now statically linked with the
JPEG and Deflate libraries; this means applications that link against
the DSO do not also need to link against these ancillary libraries
CHANGES IN THE TOOLS:
- all the tools now use common code to process compress-oriented arguments
- tiffdump should now compile on a Macintosh with MPW
CHANGES IN THE MANUAL PAGES:
CHANGES IN THE DOCUMENTATION:
CHANGES IN CONTRIBUTED SOFTWARE:
- contrib/dbs/xtiff was made to compile

facilities; consult
