====================== ==========================================
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:
Software configuration changes
------------------------------
* bit order was corrected for Pentium systems
* a new define, :c:macro:`HOST_BIGENDIAN`, was added for code that
wants to statically use information about native cpu byte order
Library changes
---------------
* the G3/G4 decoder was replaced by a new one that is faster and
has smaller state tables
* Niles Ritter's client tag extension hooks were added
* a new routine :c:func:`TIFFCurrentDirOffset` was added for
applications that want to find out the file offset of a TIFF directory
* the calculation of the number of strips in an image was corrected
for images with certain esoteric configurations
* a potential memory leak (very unlikely) was plugged
* the ``TIFFReadRGBAImage`` support was completely rewritten
and new, more flexible support was added for reading images into
a fixed-format raster
* YCbCr to RGB conversion done in the :c:func:`TIFFReadRGBAImage` support
was optimized
* a bug in JPEG support calculation of strip size was corrected
* the LZW decoder was changed to initialize the code table to zero
to lessen potential problems that arise when invalid data is decoded
* :c:func:`tiffcomp.h` is now aware of OS/2
* some function prototypes in :file:`tiffio.h` and :file:`tiffiop.h`
that contained parameter names have been changed to avoid complaints
from certain compilers
Portability support changes
---------------------------
* :file:`Makefile.in` has been corrected to use the parameters
chosen by the :program:`configure` script
Tools changes
-------------
* :program:`fax2ps` has been rewritten and moved over from the user
contributed software
* an uninitialized variable in :program:`pal2rgb` has been fixed
* :program:`ras2tiff` now converts 24-bit RGB raster data so that
samples are written in the proper order
* :program:`tiff2ps` has been updated to include fixes
and enhancements from Alberto Accomazzi
* :program:`tiffcp` now has a "``-o``" option to select a directory
by file offset
* :program:`tiffinfo` is now capable of displaying the raw undecoded
image data in a file
* :program:`tiffgt` has been rewritten to use the new ``TIFFRGBAImage``
support and to handle multiple files
