| 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. | |

| 41 | <UL> | |
| 42 | <LI>a <TT>-noninteractive</TT> flag was added to configure to | |
| 43 | control whether or not it prints and prompts for configuration information | |
| 44 | <LI>various typos and fixes were made in configure for the the | |
| 45 | library-only build support (this and other configure fixes from | |
| 46 | Richard Mlynarik <A HREF=mailto:mly@adoc.xerox.com><mly@adoc.xerox.com></A>) | |
| 47 | <LI>bugs were fixed in the handling of pathnames supplied for external | |
| 48 | packages; 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> | |

| 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> | |

| 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 | |
