| 57 | <UL> |
| 58 | <li> Applied patch from Patrick Welche (all scripts moved in the |
| 59 | 'config' and 'm4' directories). |
| 60 | |
| 61 | <li> SConstruct, libtiff/SConstruct: Added the first very preliminary |
| 62 | support for SCons software building tool (http://www.scons.org/). |
| 63 | This is experimental infrastructure and it will exist along with the |
| 64 | autotools stuff. |
| 65 | |
| 66 | <li> port/lfind.c: Added lfind() replacement module. |

| 74 | |
| 75 | <UL> |
| 76 | <li> tif_dir.c: When prefreeing tv->value in TIFFSetFieldV |
| 77 | also set it to NULL to avoid double free when re-setting custom |
| 78 | string fields as per: |
| 79 | <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=922"> |
| 80 | http://bugzilla.remotesensing.org/show_bug.cgi?id=922</a> |
| 81 | |
| 82 | <li> tif_dir.c: Fixed up support for swapping "double complex" |
| 83 | values (128 bits as 2 64 bits doubles). GDAL gcore tests now |
| 84 | pass on bigendian (macosx) system. |
| 85 | |
| 86 | <li> libtiff/{tif_dirread.c, tif_dirinfo.c}: Do not upcast BYTEs to |
| 87 | SHORTs in the TIFFFetchByteArray(). Remove TIFFFetchExtraSamples() |
| 88 | function, use TIFFFetchNormalTag() instead as per bug |
| 89 | <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=831"> |
| 90 | http://bugzilla.remotesensing.org/show_bug.cgi?id=831</a> |
| 91 | |
| 92 | Remove TIFFFetchExtraSamples() function, use TIFFFetchNormalTag() |
| 93 | instead. |
| 94 | |
| 95 | <li> tif_print.c: Fixed printing of the BYTE and SBYTE arrays. |
| 96 | |
| 97 | <li> tif_write.c: Do not check the PlanarConfiguration field in |
| 98 | the TIFFWriteCheck() function in case of single band images (as per |
| 99 | TIFF spec). |
| 100 | |
| 101 | <li> libtiff/{tif_dir.c, tif_dir.h, tif_dirinfo.c, tif_print.c}: |
| 102 | Make FieldOfViewCotangent, MatrixWorldToScreen, MatrixWorldToCamera, |
| 103 | ImageFullWidth, ImageFullLength and PrimaryChromaticities tags custom. |
| 104 | </UL> |
