24 This document describes the changes made to the software between the |
|
25 <I>previous</I> and <I>current</I> versions (see above). |
|
26 If you don't find something listed here, then it was not done in this |
|
27 timeframe, or it was not considered important enough to be mentioned. |

|
40 |
|
41 <UL> |
|
42 <LI>It is now possible to setup the software to build only the |
|
43 library; configure reconizes this is the intent when the |
|
44 <B>VERSION</B>, <B>tiff.alpha</B>, and <B>tif_version.c</B> |
|
45 files are in the local directory (i.e. ``.'') |
|
46 <LI>configure no longer tries to setup HTML materials |
|
47 <LI>include file directories needed in building the library are now |
|
48 specified with a <TT>DIRS_LIBINC</TT> config parameter |
|
49 <LI>configure no longer checks for alternate compilers if <TT>CC</TT> |
|
50 is set; if the specified compiler is not found or is not appropriate |
|
51 the configuration procedure aborts |
|
52 <LI>the <B>port.h</B> file generated by configure is now used only by |
|
53 the library and as such as have been moved to the <B>libtiff</B> |
|
54 directory |
|
55 <LI>there is beginning support for building DSO's on systems other than IRIX |
|
56 <LI>configure now verifies the JPEG and zlib directory pathnames by |
|
57 checking for well-known include files in these directories |
|
58 <LI>configure no longer creates the <B>dist</B> directory needed only |
|
59 on SGI machines (for building SGI binary distributions) |
|
60 <LI>a bug was fixed whereby configure would incorrectly set |
|
61 <TT>ENVOPTS</TT> when building the software with gcc under AIX |
|
62 </UL> |

|
67 |
|
68 <UL> |
|
69 <LI>two new typedefs were added to <B>tiff.h</TT>: <TT>int8</TT> |
|
70 and <TT>uint8</TT> for signed and unsigned 8-bit quantities, |
|
71 respectively; these are currently used only by |
|
72 programs in the <B>tools</B> directory |
|
73 <LI>the <TT>BadFaxLines</TT>, <TT>CleanFaxData</TT>, and |
|
74 <TT>ConsecutiveBadFaxLines</B> tags are now supported with |
|
75 Group 4 compression |
|
76 <LI>byte order is now correctly identified on 64-bit machines |
|
77 <LI>a bug was fixed in the PackBits decoder where input data would |
|
78 appear short when a no-op run was present |
|
79 <LI>a bug was fixed in calculations with very wide strips |
|
80 <LI><TT>TIFFWriteEncodedStrip</TT> and <TT>TIFFWriteRawStrip</TT> |
|
81 were extended to support dynamically growing the number of |
|
82 strips in an image (must set <TT>ImageLength</TT> prior to |
|
83 making calls though) |
|
84 <LI><TT>TIFFDefaultTileSize</TT> now rounds tile width and height |
|
85 up to a multiple of 16 pixels, as required by the TIFF 6.0 specification |
|
86 <LI>the file <B>version.h</B> is now built by a new <B>mkversion</B> |
|
87 program; this was done for portability to non-UNIX systems |
|
88 <LI>support was added for the Acorn RISC OS (from Peter Greenham) |
|
89 <LI>the builtin codec table is now made <TT>const</TT> when compiling |
|
90 under VMS so that <B>libtiff</B> can be built as a shared library |
|
91 <LI>support for the PowerPC Mac (from Ruedi Boesch) |
|
92 <LI>support for Window NT/Window 95 (from Scott Wagner) |

|
100 <LI>the tools no longer include <B>port.h</B> |
|
101 <LI>various portability fixes; mostly to eliminate implicit assumptions |
|
102 about how long <TT>int32</TT> data types are |
|
103 <LI>PostScript Level II additions to <TT>tiff2ps</TT> from Bjorn Brox |
|
104 <LI><TT>sgi2tiff</TT> now handles RGBA images |
