Changes in TIFF v3.7.1
======================
.. table:: References
:widths: auto
====================== ==========================================
Current Version v3.7.1 (:tag:`Release-v3-7-1`)
Previous Version :doc:`v3.7.0 <v3.7.0>`
Master Download Site `<https://download.osgeo.org/libtiff/>`_
Master HTTP Site `<http://www.simplesystems.org/libtiff/>`_
====================== ==========================================
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:
Major changes
-------------
* This is mostly bugfix release. Most important fix is the one
related to wrong custom tag read/write code.
Software configuration changes
------------------------------
* :file:`autogen.sh`: :program:`aclocal` and :program:`autoheader`
should be executed after :program:`libtoolize`.
Also add ``-I .`` to aclocal invocation to check
current directory for macros.
* nmake.opt: Link with the :file:`user32.lib` in windowed mode. As per bug
:bugzilla-rs:`697`
* :file:`nmake.opt`, :file:`makefile.vc`: make it easier to rename the libtiff DLL.
* :file:`configure`, :file:`configure.ac`: Added ``--enable-rpath`` option to embed
linker paths into library binary.
Library changes
---------------
* :file:`tiff.h`: Revert back libtiff data type definitions as per
bug :bugzilla-rs:`687`
* :file:`tif_dirread.c`: Do not forget about :c:macro:`TIFF_VARIABLE2` when
checking for tag count in :c:func:`TIFFReadDirectory` function. As per bug
:bugzilla-rs:`713`
* :file:`tif_getimage.c`: Support for multiple-alpha-channelled
RGB-images as per bug
:bugzilla-rs:`718`
* :file:`tif_getimage.c`: ``#define A1`` bracketing for clean build on
SunPro compiler.
* :file:`tif_dirwrite.c`: Always write :c:macro:`TIFFTAG_SUBIFD` using ``LONG`` type
as per bugs
:bugzilla-rs:`703` and
:bugzilla-rs:`704`.
* :file:`tif_win32.c`: Use :c:expr:`char*` strings instead of :c:type:`TCHAR` in windowed
mode as per bug
:bugzilla-rs:`697`
* :file:`tif_dir.c`, :file:`tif_dirread.c`: Remove :c:func:`TIFFReassignTagToIgnore`
call from the :c:func:`TIFFReadDirectory` function. :c:func:`TIFFReassignTagToIgnore`
must be removed in the future, as it was never used properly. As per
bug :bugzilla-rs:`692`
* :file:`tif_jpeg.c`: Added a work-around in order to allow
compilation with the heavily modified version of libjpeg delivered
with Cygwin.
* :file:`tif_dir.c`: Properly handle tags, which have the :c:type:`uint32`
counts. As per bug
:bugzilla-rs:`693`
* :file:`tif_unix.c`: Make UNIX module compilable (and usable)
on Windows.
* :file:`tiff.h`: Added Adobe DNG tags.
* :file:`tif_aux.c`: Set the appropriate ``ReferenceBlackWhite`` array for
YCbCr image which lacks that tag (noted by Hans Petter Selasky).
* :file:`tif_color.c`: Division by zero fixed (Hans Petter Selasky).
* :file:`tif_stream.cxx`, :file:`tiffio.h`: Added C++ stream interface
contributed by Edward Lam (see
:bugzilla-rs:`654`
for details). Those who want to use C++ streams should
``#include <tiffio.hxx>``.
* :file:`tif_open.c`: Removed :c:func:`close` in :c:func:`TIFFClientOpen` if file
is bad. This is the callers responsibility.
:bugzilla-rs:`651`
* :file:`tiffio.h`, :file:`tif_win32.c`, :file:`libtiff.def`: Added :c:func:`TIFFOpenW`
function to work with the double byte strings (used to represent
filenames in some locales). As per bug
:bugzilla-rs:`625`
* :file:`tif_dirread.c`: Fixed problem when fetching ``BitsPerSample`` and
``Compression`` tags of type ``LONG`` from broken TIFFs as per bug
:bugzilla-rs:`662`
* :file:`tif_dirinfo.c`: Fixed definition for ``TIFFTAG_RICHTIFFIPTC``,
the writecount should have :c:type:`uint32` type. As per bug
:bugzilla-rs:`662`
* :file:`tif_write.c`: Fixed wrong ``if()`` statement in
:c:func:`TIFFAppendToStrip` function as per bug
:bugzilla-rs:`660`
* :file:`tif_dirinfo.c`: Change definition for ``TIFFTAG_EXTRASAMPLES``
field. The caller should supply a count when setting this field. As
per bug :bugzilla-rs:`648`.
* :file:`tif_jpeg.c`, :file:`tif_ojpeg.c`: ``TIFFTAG_JPEGTABLES`` should have
uint32 count. Use this type everywhere.
* :file:`tif_next.c`: avoid use of :c:type:`u_long` and :c:type:`u_char` types.
* :file:`tif_fax3.c`: Fixed case with the wrong decode routines
choosing when the incorrect ``Group4Options`` tag set. As per bug
:bugzilla-rs:`323`
* :file:`tif_dirwrite.c`: Fixed problem with passing count variable of
wrong type when writing the :c:macro:`TIFF_BYTE`/:c:macro:`TIFF_SBYTE` tags in
:c:func:`TIFFWriteNormalTag`.
* :file:`tif_compress.c`: Zero division problem fixed (Vladimir Nadvornik,
Dmitry V. Levin).
Tools changes
-------------
* :file:`fax2ps.c`: Be able to extract the first page (#0). As per bug
:bugzilla-rs:`690`
* :file:`tiff2ps.c`: Fixed wrong variable data type when read ``Position``
tags (Tristan Hill).
* :file:`tiff2ps.c`: Fixed wrong variable data type when read ``Resolution``
tags (Peter Fales).
* :file:`tiffset.c`: Check the :c:func:`malloc` return value (Dmitry V. Levin).
Contributed software changes
----------------------------
* None.
