- Existing EXIF field definition of tags is upgraded to EXIF version 2.3.2
- EXIF-GPS structure, tags and access functions are added as special CustomDirectory (like it was done for EXIF).
- Test program custom_dir_EXIF_231.c added to test writing/reading of EXID IFD and GPS IFD tags
and to highlight some quirks of IFD-handling and peculiarities of reading/writing the different data types.
- Reading error for FileSource and SceneType tags corrected.
- EXIF_GPS_upgrade rebased onto c8c5309b76 (Merge branch 'Rational2DoublePrecision_correction' into 'master')
and adapted:
- tif_dirinfo.c: All rational tags set to TIFF_SETGET_FLOAT but only the GPSTAG_ tags set to TIFF_SETGET_DOUBLE.
- custom_dir_EXIF_231.c: Editorials amended and gcc warnigs fixed.
- CMakeLists.txt: add_test(NAME "custom_dir_EXIF_231" COMMAND "custom_dir_EXIF_231") added.
