e.g. <TT>DIR_JPEG</TT> 49<LI>the handling of <TT>SETMAKE</TT> is now done properly 50<LI>the default prototype function declaration for <TT>pow</TT> was corrected 51<LI>a bug was fixed in <B>libtiff/Makefile.in</B> that caused installation 52 to fail on systems without DSO support 53</UL> 54 55<P><HR WIDTH=65% ALIGN=right> 56 57<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A> 58 59<UL> 60<LI>Acorn RISC O/S support that was accidentally left out of the 61 left out of the previous distribution is present (from Peter Greenham) 62<LI>complaints about unknown and/or unsupported codecs have been 63 delayed until they are invoked; this permits applications to open 64 images and look at tags even if the image data is compressed with 65 an unknown/unsupported compression scheme 66<LI>bugs in handling unknown tags have been corrected; applications 67 that use multiple codecs, each with codec-specific tags, no longer 68 generate confusing error messages 69<LI>a missing pseudo-tag definition in the CCITT G3 codec was fixed 70 (this problem caused core dumps in the <TT>tiffcp</TT> program) 71<LI>pseudo-tags are now treated specially; they are always considered 72 to be set (i.e. they do not use bits in the <TT>FIELD_*</TT> bit-vectors). 73<LI>the use of strip chopping can now be controlled on a per-file basis 74 through a mode parameter supplied when opening a file (``C'' to 75 enable strip chopping and ``c'' to disable) 76<LI>two bugs were fixed in the writing of opposite-endian byte-order 77 files 78<LI>support was added for three new fax-related tags registered to 79 SGI: FaxRecvParams, FaxRecvTime, and FaxSubAddress 80<LI>the bit order of image data read and written can now be controlled 81 on a per-file basis through a mode parameter supplied when opening 82 a file (``B'' to force MSB2LSB bit order, ``L'' for LSB2MSB bit 83 order, and ``H'' for the bit order of the native CPU) 84<LI>the byte order of image and tag data written to newly-created files 85 can now be controlled on a per-file basis through a mode parameter 86 supplied when openening a file (``b'' to force Big-Endian byte order 87 and ``l'' to force Little-Endian byte order) 88<LI>the use memory-mapped files for images opened read-only can now 89 be controlled on a per-file basis through a mode parameter supplied 90 when opening a file (``M'' to enable use of memory-mapped files 91 and ``m'' to disable use) 92<LI>the use of the <TT>WIN32</TT> define in <B>tiffiop.h</B> has 93 been replaced by <TT>__WIN32__</TT> 94</UL> 95 96<P><HR WIDTH=65% ALIGN=right> 97 98<A NAME="tools"><B><FONT SIZE=+3>C</FONT>HANGES IN THE TOOLS:</B></A> 99 100<UL> 101<LI><TT>fax2ps</TT> now does a <TT>save</TT> and <TT>restore</TT> 102 around each page of PostScript; this fixes a problem with VM 103 overflow when printing a many-page document on some printers 104<LI>a bug in the handling of 3-channel images by <TT>ras2tiff</TT> 105 was fixed 106<LI><TT>tiffcp</TT> has new options to control the byte order of 107 newly created files: <B>-B</B> for Big-Endian byte order, <B>-L</B> 108 for Little-Endian byte order; a <B>-M</B> option to disable the 109 use of memory-mapped files, and a <B>-C</B> option to disable the 110 use of strip chopping 111<LI>bugs were fixed in <TT>tiffcp</TT>'s handling of codec-specific tags 112</UL> 113 114<P><HR WIDTH=65% ALIGN=right> 115 116<A NAME="man"><B><FONT SIZE=+3>C</FONT>HANGES IN THE MANUAL PAGES:</B></A> 117 118<UL> 119<LI>the <TT>TIFFOpen</TT> page has been updated to reflect the new 120 optional open mode parameters 121</UL> 122 123<P><HR WIDTH=65% ALIGN=right> 124 125<A NAME="contrib"><B><FONT SIZE=+3>C</FONT>HANGES IN THE CONTRIBUTED SOFTWARE:</B></A> 126 127<UL> 128<LI><B>contrib/win95</B> contains information and code from Philippe Tenenhaus 129 <A HREF=mailto:100423.3705@compuserve.com><100423.3705@compuserve.com></A> 130 about using the software under Windows 95 131<LI><B>contrib/winnt</B> contains information and code from Dave Dyer 132 <A HREF=mailto:ddyer@triple-i.com><ddyer@triple-i.com></A> 133 about using the software under Windows NT 134</UL> 135 136<A HREF="index.html"><IMG SRC="images/back.gif"></A> TIFF home page.<BR> 137 138<HR> 139 140<ADDRESS> 141<A HREF="sam.html">Sam Leffler</A> / <A HREF="mailto:sam@engr.sgi.com">sam@engr.sgi.com</A> 142Last updated $Date: 2016-09-25 20:05:45 $. 143</ADDRESS> 144 145</BODY> 146</HTML> 147
