| 47 | |
| 48 | <ul> |
| 49 | <li> LZW compression enabled by default. You don't need the separate |
| 50 | compression kit anymore. |
| 51 | |
| 52 | <li> bmp2tiff: Added new utility to convert Windows BMP files |
| 53 | into TIFFs. |
| 54 | |
| 55 | <li> The first attempt to implement a test suite. |
| 56 | </ul> |

| 63 | |

| 74 | <UL> |
| 75 | <li> libtiff/{tif_luv.c, tif_next.c, tif_thunder.c}: Several buffer |
| 76 | overruns fixed, as noted by Chris Evans. |
| 77 | |
| 78 | <li> BSD data types (u_char, u_short, u_int, u_long) is no longer |
| 79 | used internally in the libtiff. Should result in simpler configuration |
| 80 | and better portability. |
| 81 | |
| 82 | <li> libtiff/tiff.h: Fix column tagging. Reference current Adobe XMP |
| 83 | specification. Reference libtiff bug tracking system to submit |
| 84 | private tag additions. |
| 85 | |
| 86 | <li> libtiff/tif_dirread.c: Don't reject to read tags of the |
| 87 | SamplesPerPixel size when the tag count is greater than number of |
| 88 | samples as per bug |

| 90 | http://bugzilla.remotesensing.org/show_bug.cgi?id=576</A>. |
| 91 | |
| 92 | <li> libtiff/{tiffio.h, tif_open.c}: Applied patches from |
| 93 | Joris Van Damme to avoid requirement for tiffiop.h inclusion in |
| 94 | some applications. Look for details here: |

| 99 | variable as per bug |

| 102 | |
| 103 | <li> libtiff/tif_lzw.c: LZW compression code is merged back from the |
| 104 | separate package. All libtiff tools are updated to not advertise an |
| 105 | abcence of LZW support. |
| 106 | |
| 107 | <li> libtiff/tif_dir.c: Call TIFFError() instead of producing warnings |
| 108 | when setting custom tags by value. Reported by Eric Fieleke. |
