<I>previous</I> and <I>current</I> 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. | |

<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A> | |
<UL> | |
<LI>It is now possible to setup the software to build only the | |
library; configure reconizes this is the intent when the | |
<B>VERSION</B>, <B>tiff.alpha</B>, and <B>tif_version.c</B> | |
files are in the local directory (i.e. ``.'') | |
<LI>configure no longer tries to setup HTML materials | |
<LI>include file directories needed in building the library are now | |
specified with a <TT>DIRS_LIBINC</TT> config parameter | |
<LI>configure no longer checks for alternate compilers if <TT>CC</TT> | |
is set; if the specified compiler is not found or is not appropriate | |
the configuration procedure aborts | |
<LI>the <B>port.h</B> file generated by configure is now used only by | |
the library and as such as have been moved to the <B>libtiff</B> | |
directory | |
<LI>there is beginning support for building DSO's on systems other than IRIX | |
<LI>configure now verifies the JPEG and zlib directory pathnames by | |
checking for well-known include files in these directories | |
<LI>configure no longer creates the <B>dist</B> directory needed only | |
on SGI machines (for building SGI binary distributions) | |
<LI>a bug was fixed whereby configure would incorrectly set | |
<TT>ENVOPTS</TT> when building the software with gcc under AIX | |
</UL> | |
<P><HR WIDTH=65% ALIGN=right> | |
<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A> | |
<UL> | |
<LI>two new typedefs were added to <B>tiff.h</TT>: <TT>int8</TT> | |
and <TT>uint8</TT> for signed and unsigned 8-bit quantities, | |
respectively; these are currently used only by | |
programs in the <B>tools</B> directory | |
<LI>the <TT>BadFaxLines</TT>, <TT>CleanFaxData</TT>, and | |
<TT>ConsecutiveBadFaxLines</B> tags are now supported with | |
Group 4 compression | |
<LI>byte order is now correctly identified on 64-bit machines | |
<LI>a bug was fixed in the PackBits decoder where input data would | |
appear short when a no-op run was present | |
<LI>a bug was fixed in calculations with very wide strips | |
<LI><TT>TIFFWriteEncodedStrip</TT> and <TT>TIFFWriteRawStrip</TT> | |
were extended to support dynamically growing the number of | |
strips in an image (must set <TT>ImageLength</TT> prior to | |
making calls though) | |
<LI><TT>TIFFDefaultTileSize</TT> now rounds tile width and height | |
up to a multiple of 16 pixels, as required by the TIFF 6.0 specification | |
<LI>the file <B>version.h</B> is now built by a new <B>mkversion</B> | |
program; this was done for portability to non-UNIX systems | |
<LI>support was added for the Acorn RISC OS (from Peter Greenham) | |
<LI>the builtin codec table is now made <TT>const</TT> when compiling | |
under VMS so that <B>libtiff</B> can be built as a shared library | |
<LI>support for the PowerPC Mac (from Ruedi Boesch) | |
<LI>support for Window NT/Window 95 (from Scott Wagner) | |
</UL> | |
<P><HR WIDTH=65% ALIGN=right> | |
<A NAME="tools"><B><FONT SIZE=+3>C</FONT>HANGES IN THE TOOLS:</B></A> | |
<UL> | |
<LI>the tools no longer include <B>port.h</B> | |
<LI>various portability fixes; mostly to eliminate implicit assumptions | |
about how long <TT>int32</TT> data types are | |
<LI>PostScript Level II additions to <TT>tiff2ps</TT> from Bjorn Brox | |
<LI><TT>sgi2tiff</TT> now handles RGBA images | |
</UL> | |
<P><HR WIDTH=65% ALIGN=right> | |
<A NAME="man"><B><FONT SIZE=+3>C</FONT>HANGES IN THE MANUAL PAGES:</B></A> | |
<UL> | |
<LI>the documentation has been updated to reflect the current state of | |
the software | |
<LI>some routines have been moved to different manual pages | |
to group like-routines together | |
</UL> | |
<P><HR WIDTH=65% ALIGN=right> | |
<A NAME="contrib"><B><FONT SIZE=+3>C</FONT>HANGES IN THE CONTRIBUTED SOFTWARE:</B></A> | |
<UL> | |
<LI>support was added for the Acorn RISC OS (from Peter Greenham) | |
<LI>support for Windows NT/Windows 95 contributed for a previous | |
version of this software was sort of incorporated (it's broken | |
right now) (from Scott Wagner) | |
