- 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.

*=========== Purpose ===================================================================================
|
|
* Extended and amended version for testing of EXIF 2.32, GPS and handling of custom fields.
|
|
* EXIF 2.32 and GPS are defined in amended files tif_dirinfo.c, tif_dirread.c, tiff.h, tiffio.h, tif_dir.h, tif_dir.c
|
|
*
|
|
*-- ATTENTION: After the upgrade with Rational2Double, the GPSTAG values are defined as double precision
|
|
* and need to be written and also read in double precision!
|
|
* In order to maintain this code for both cases, it is checked above if the TiffLibrary is
|
|
* compiled with the new interface with Rational2Double or still uses the old definitions,
|
|
* by setting blnIsRational2Double above.
