e.g. <TT>DIR_JPEG</TT> 48<LI>the handling of <TT>SETMAKE</TT> is now done properly 49<LI>the default prototype function declaration for <TT>pow</TT> was corrected 50<LI>a bug was fixed in <B>libtiff/Makefile.in</B> that caused installation 51 to fail on systems without DSO support 52</UL> 53 54<P><HR WIDTH=65% ALIGN=right> 55 56<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A> 57 58<UL> 59<LI>Acorn RISC O/S support that was accidentally left out of the 60 left out of the previous distribution is present (from Peter Greenham) 61<LI>complaints about unknown and/or unsupported codecs have been 62 delayed until they are invoked; this permits applications to open 63 images and look at tags even if the image data is compressed with 64 an unknown/unsupported compression scheme 65<LI>bugs in handling unknown tags have been corrected; applications 66 that use multiple codecs, each with codec-specific tags, no longer 67 generate confusing error messages 68<LI>a missing pseudo-tag definition in the CCITT G3 codec was fixed 69 (this problem caused core dumps in the <TT>tiffcp</TT> program) 70<LI>pseudo-tags are now treated specially; they are always considered 71 to be set (i.e. they do not use bits in the <TT>FIELD_*</TT> bit-vectors). 72<LI>the use of strip chopping can now be controlled on a per-file basis 73 through a mode parameter supplied when opening a file (``C'' to 74 enable strip chopping and ``c'' to disable) 75<LI>two bugs were fixed in the writing of opposite-endian byte-order 76 files 77<LI>support was added for three new fax-related tags registered to 78 SGI: FaxRecvParams, FaxRecvTime, and FaxSubAddress 79<LI>the bit order of image data read and written can now be controlled 80 on a per-file basis through a mode parameter supplied when opening 81 a file (``B'' to force MSB2LSB bit order, ``L'' for LSB2MSB bit 82 order, and ``H'' for the bit order of the native CPU) 83<LI>the byte order of image and tag data written to newly-created files 84 can now be controlled on a per-file basis through a mode parameter 85 supplied when openening a file (``b'' to force Big-Endian byte order 86 and ``l'' to force Little-Endian byte order) 87<LI>the use memory-mapped files for images opened read-only can now 88 be controlled on a per-file basis through a mode parameter supplied 89 when opening a file (``M'' to enable use of memory-mapped files 90 and ``m'' to disable use) 91<LI>the use of the <TT>WIN32</TT> define in <B>tiffiop.h</B> has 92 been replaced by <TT>__WIN32__</TT> 93</UL> 94 95<P><HR WIDTH=65% ALIGN=right> 96 97<A NAME="tools"><B><FONT SIZE=+3>C</FONT>HANGES IN THE TOOLS:</B></A> 98 99<UL> 100<LI><TT>fax2ps</TT> now does a <TT>save</TT> and <TT>restore</TT> 101 around each page of PostScript; this fixes a problem with VM 102 overflow when printing a many-page document on some printers 103<LI>a bug in the handling of 3-channel images by <TT>ras2tiff</TT> 104 was fixed 105<LI><TT>tiffcp</TT> has new options to control the byte order of 106 newly created files: <B>-B</B> for Big-Endian byte order, <B>-L</B> 107 for Little-Endian byte order; a <B>-M</B> option to disable the 108 use of memory-mapped files, and a <B>-C</B> option to disable the 109 use of strip chopping 110<LI>bugs were fixed in <TT>tiffcp</TT>'s handling of codec-specific tags 111</UL> 112 113<P><HR WIDTH=65% ALIGN=right> 114 115<A NAME="man"><B><FONT SIZE=+3>C</FONT>HANGES IN THE MANUAL PAGES:</B></A> 116 117<UL> 118<LI>the <TT>TIFFOpen</TT> page has been updated to reflect the new 119 optional open mode parameters 120</UL> 121 122<P><HR WIDTH=65% ALIGN=right> 123 124<A NAME="contrib"><B><FONT SIZE=+3>C</FONT>HANGES IN THE CONTRIBUTED SOFTWARE:</B></A> 125 126<UL> 127<LI><B>contrib/win95</B> contains information and code from Philippe Tenenhaus 128 <A HREF=mailto:[email protected]><[email protected]></A> 129 about using the software under Windows 95 130<LI><B>contrib/winnt</B> contains information and code from Dave Dyer 131 <A HREF=mailto:[email protected]><[email protected]></A> 132 about using the software under Windows NT 133</UL> 134 135<A HREF="index.html"><IMG SRC="images/back.gif"></A> TIFF home page.<BR> 136 137<HR> 138 139<ADDRESS> 140<A HREF="sam.html">Sam Leffler</A> / <A HREF="mailto:[email protected]">[email protected]</A> 141Last updated $Date: 1999-07-27 21:50:27 $. 142</ADDRESS> 143 144</BODY> 145</HTML> 146
