Changes in TIFF v3.6.1
======================
.. table:: References
:widths: auto
====================== ==========================================
Current Version v3.6.1 (:tag:`Release-v3-6-1`)
Previous Version :doc:`v3.6.0 <v3.6.0>`
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
-------------
* New utility :program:`tiff2pdf`
for converting TIFF images directly into PDF.
* New :doc:`TIFFColor` color conversion module.
* Full support for ``Orientation`` tag in ``TIFFRGBAImage`` interface.
* Many bugs fixed.
Software configuration changes
------------------------------
* :file:`libtiff/makefile.vc`, :file:`tools/makefile.vc`: Support for IJG JPEG library.
* :file:`Makefile.in`: Add an absolute path to the :file:`test_pics.sh` call.
* :file:`Makefile.in`: Add an absolute path to the :file:`test_pics.sh` call.
* :file:`libtiff/tiffcomp.h`: ``#define _BSDTYPES_DEFINED`` when defining BSD typedefs.
* :file:`configure`, :file:`libtiff/Makefile.in`, :file:`libtiff/mkversion.c`: Relative buildings fixed.
* :file:`Makefile.in`: Add an absolute path to the :file:`test_pics.sh` call.
Library changes
---------------
* :file:`libtiff/tif_color.c`, :file:`libtiff/tif_getimage.c`, :file:`libtiff/tiffio.h`:
Added support for ``ReferenceBlackWhite`` tag handling when converted from YCbCr color space as
per bug :bugzilla-rs:`120`.
* :file:`libtiff/tif_getimage.c`, :file:`libtiff/tif_aux.c`: Read ``WhitePoint`` tag from the
file and properly use it for CIE Lab 1976 to RGB transform.
* :file:`libtiff/tif_getimage.c`, :file:`libtiff/tiffio.h`: Finally resolved problems with
orientation handling. ``TIFFRGBAImage`` interface now properly supports all
possible orientations, i.e. images will be flipped both in horizontal and
vertical directions if required. 'Known bugs' section now removed from the
appropriate manual pages.
* :file:`libtiff/tif_luv.c`: Fixed bug in 48-bit to 24-bit conversion routine,
reported by Antonio Scuri.
* :file:`libtiff/tiffio.h`, :file:`libtiff/tif_codec.c`: Added new function
:c:func:`TIFFIsCODECConfigured`, suggested by Ross Finlayson.
* :file:`libtiff/tif_ojpeg.c`: :c:func:`TIFFVGetField` function now can properly extract
the fields from the OJPEG files. Patch supplied by Ross Finlayson.
* :file:`libtiff/tif_dir.h`: :c:func:`_TIFFFindOrRegisterdInfo` declaration replaced
with :c:func:`_TIFFFindOrRegisterFieldInfo` as reported by Ross Finlayson.
* :file:`libtiff/tif_dirinfo.c`: Implemented binary search in :c:func:`_TIFFMergeFieldInfo`.
Patch supplied by Ross Finlayson.
* :file:`tif_dirread.c`: do not mark all anonymously defined tags to be ``IGNORE`` (as
it was done in 3.6.0).
* :file:`libtiff/tiff.h`, :file:`libtiff/tif_dirinfo.c`: Added support for IFD (13) datatype,
introduced in "Adobe PageMaker TIFF Technical Notes".
* :file:`libtiff/tif_color.c`, :file:`libtiff/tif_getimage.c`, :file:`libtiff/tiffio.h`: New color space
conversion code: CIE L*a*b* 1976 images now supported by the ``TIFFRGBAImage``
interface. YCbCr to RGB conversion code also moved there and now has
:doc:`TIFFcolor` publicly available interface. These
routines currently used in ``TIFFRGBAImage`` interface only and not supported in
other libtiff tools yet. So if you want, for example, to convert CIE Lab image
into PostScript file you should do it in two steps: change colorspace to RGB
using :program:`tiff2rgba` utility and then process
it with the :program:`tiff2ps`.
* :file:`libtiff/tif_tile.c`: Remove spurious use of "s" (sample) in the
``planarconfig_contig`` case in :c:func:`TIFFComputeTile` as per bug :bugzilla-rs:`387`.
* :file:`libtiff/tiffiop.h`: New macros: :c:macro:`TIFFmax` and :c:macro:`TIFFmin`.
* :file:`libtiff/tiffio.h`, :file:`libtiff/tif_strip.c`: Added :c:func:`TIFFRawStripSize` function
as suggested by Chris Hanson.
* :file:`libtiff/tif_lzw.c`, :file:`libtiff/tif_fax3.c`: Proper support for update mode
as per bug :bugzilla-rs:`424`.
Tools changes
-------------
* :program:`tiff2pdf`:: New tool, written by
Ross Finlayson, to directly convert TIFF files to PDF.
* :program:`tiffgt`: Unmaintained and platform
dependent sgigt utility removed and replaced with the completely rewritten
portable tool (depend on OpenGL and
GLUT). This tool will not build by default.
* :program:`ras2tiff`: Properly determine
SUN Rasterfiles with the reverse byte order (it is reported by the magic
header field). Problem reported by Andreas Wiesmann.
* :program:`raw2tiff`: Implemented image size
guessing using correlation coefficient calculation between two neighbour
lines.
Contributed software changes
----------------------------
* :file:`contrib/pds/tif_pdsdirread.c`, :file:`contrib/pds/tif_pdsdirwrite.c`:
Use :c:func:`TIFFDataWidth` function instead of :c:var:`tiffDataWidth` array.
LZW compression kit changes
---------------------------
* Proper support for update mode as per bug :bugzilla-rs:`424`.
