Changes in TIFF v3.7.3
======================
.. table:: References
:widths: auto
====================== ==========================================
Current Version v3.7.3 (:tag:`Release-v3-7-3`)
Previous Version :doc:`v3.7.2 <v3.7.2>`
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
-------------
* Replace runtime endianness check with the compile time one.
* Added support for the new predictor type (floating point
predictor), defined at the TIFF Technical Note 3.
* Added Support for custom tags, passed by value.
* Added support for all DNG tags.
Software configuration changes
------------------------------
* Do not use empty ``-R`` option when linking with ``--enable-rpath``.
* Added workaround for OpenBSD/MirOS soname problem as per bug
:bugzilla-rs:`838`
* Fixed parallel compilation of the libtiff and
libtiffxx libraries as per bug
:bugzilla-rs:`826`
* :file:`configure.ac`, :file:`libtiff/Makefile.am`: Use libtool machinery to pass
``rpath`` option.
* :file:`make.opt`: Build with Win32 CRT library by default.
Library changes
---------------
* :file:`tiffiop.h`, :file:`tif_open.c`: Added open option "``h``" to avoid reading
the first IFD when needed. As per bug
:bugzilla-rs:`875`
* :file:`tiff.h`: Use correct :c:expr:`int` size on Sparc 64bit/Sun compiler
platform. As per bug
:bugzilla-rs:`855`
* :file:`tif_dirinfo.c`: Added support for ``ClipPath``, ``XClipPathUnits``
and ``YClipPathUnits`` tags.
* :file:`tif_dirinfo.c`, :file:`tif_dir.h`, :file:`tif_dir.c`, :file:`tif_print.c`: Make
``DocumentName``, ``Artist``, ``HostComputer``, ``ImageDescription``, ``Make``, ``Model``,
``Copyright``, ``DateTime``, ``PageName``, ``TextureFormat``, ``TextureWrapModes`` and
``TargetPrinter`` tags custom.
* :file:`tif_jpeg.c`: Cleanup the codec state depending on :c:macro:`TIFF_CODERSETUP`
flag (to fix memory leaks).
* :file:`tif_dirwrite.c`: Use :c:member:`tdir_count` when calling
:c:func:`TIFFCvtNativeToIEEEDouble` in the :c:func:`TIFFWriteDoubleArray` function as
per bug :bugzilla-rs:`845`
* :file:`tif_dirinfo.c`, :file:`tif_print.c`: :c:func:`TIFFFetchByteArray` returns
:c:type:`uint16` array when fetching the ``BYTE`` and ``SBYTE`` fields, so we should
consider result as pointer to :c:type:`uint16` array and not as array of :c:expr:`char`.
As per bug
:bugzilla-rs:`831`
* :file:`tif_dir.c`: More efficient custom tags retrieval as per bug
:bugzilla-rs:`830`
* :file:`tif_win32.c`: Use ``FILE_SHARE_READ | FILE_SHARE_WRITE`` share
mode in ``CreateFile`` call as per bug
:bugzilla-rs:`829`
* :file:`tif_jpeg.c`: Substantial fix for :program:`addtiffo` problems with
JPEG encoded TIFF files. Pre-allocate lots of space for jpegtables
in directory.
* :file:`tif_dirread.c`: Changed the code that computes
``stripbytecount[0]`` if it appears bogus to ignore if ``stripoffset[0]`` is
zero. This is a common case with GDAL indicating a "null" tile/strip.
* :file:`tif_jpeg.c`: added ``LIB_JPEG_MK1`` support in :c:func:`JPEGDecodeRaw`.
* :file:`tif_dirread.c`: Ensure that broken files with too many
values in :c:func:`TIFFFetchPerSampleShorts`, :c:func:`TIFFFetchPerSampleLongs` and
:c:func:`TIFFFetchPerSampleAnys` work ok instead of crashing.
:bugzilla-rs:`843`
* :file:`tif_predict.h`, :file:`tif_predict.c`: Added ability to decode and encode
floating point predictor, as per TIFF Technical Note 3.
See http://chriscox.org/TIFF_TN3_Draft2.pdf for details.
* :file:`tiffio.h`, :file:`tiffiop.h`, :file:`tif_dir.c`, :file:`tif_read.c`, :file:`tif_swab.c`:
Added :c:func:`_TIFFSwab24BitData` and :c:func:`TIFFSwabArrayOfLong` functions used to
swap 24-bit floating point values.
* :file:`tiff.h`: Added predictor constants.
* :file:`tiffiop.h`, :file:`tif_dir.c`: Use :c:type:`uint32` type for appropriate values
in :c:func:`_TIFFVSetField` function. Inspired by the bug
:bugzilla-rs:`816`
* :file:`tif_open.c`: Do not read header in case the output file should
be truncated (Ron).
* :file:`tif_dirinfo.c`, :file:`tif_config.h`.vc: Use :c:func:`lfind` instead of :c:func:`bsearch`
in :c:func:`_TIFFFindFieldInfoByName` function (Ron).
* :file:`tif_dir.c`, :file:`tif_print.c`: Properly handle all data types in custom
tags.
* :file:`dirinfo.c`: Added DNG tags.
* :file:`tiff.h`: Added missed DNG tag (``LensInfo``); added DNG 1.1.0.0 tags.
* :file:`tif_dir.c`, :file:`tif_print.c`: Added Support for custom tags, passed
by value.
* :file:`tiff.h`, :file:`tif_dirinfo.c`, :file:`tiffiop.h`: Added EXIF related tags.
Tools changes
-------------
* :file:`tiff2pdf.c`: Print two characters per loop in the
:c:func:`t2p_write_pdf_trailer`. As per bug
:bugzilla-rs:`594`
* :file:`tiffgt.c`: Use MacOS X OpenGL framework when appropriate. As
per bug :bugzilla-rs:`844`
* :file:`ppm2tiff.c`: Fixed format string when read PPM file header with
the :c:func:`fscanf` function. As per bug
:bugzilla-rs:`861`
* :file:`tiffsplit.c`: Check for ``JPEGTables`` tag presence before copying.
* :file:`tiff2pdfr.c`: Calculate the tile width properly; added new
option "``-b``" to use interpolation in output PDF files (Bruno Ledoux).
* :file:`tiffdither.c`: Copy the `PhotometricInterpretation` tag from the
input file.
* :file:`tif2pdf.c`: Fixed problem with alpha channel handling as per
bug :bugzilla-rs:`794`.
Contributed software changes
----------------------------
* :file:`addtiffo/tif_overview.c`, :file:`addtiffo/tif_ovrcache.c`,
:file:`addtiffo/tif_ovrcache.h`:
Make overviews working for contiguous images.
