Changes in TIFF v3.4beta016 =========================== .. table:: References :widths: auto ====================== ========================================== Current Version v3.4beta016 (no release tag) Previous Version v3.4beta004 (no references to earlier releases exist) Master Download Site ``_ ====================== ========================================== 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
