Changes from version 0.4 to 0.5
|
|
|
|
|
-------------------------------
|
|
|
|
|
|
|
|
|
|
* Exiv2 utility
|
|
|
|
|
|
|
|
|
|
* Added -pI print mode to print Iptc data.
|
|
|
|
|
|
|
|
|
|
* Bugfix: Use timegm() and gmtime() instead of mktime() and
|
|
|
|
|
localtime() to avoid problems when adjusting timestamps.
|
|
|
|
|
Thanks to Samir Rostum for pointing out this bug.
|
|
|
|
|
|
|
|
|
|
* Added timegm() from the tz distribution for platforms which
|
|
|
|
|
do not have this function.
|
|
|
|
|
|
|
|
|
|
* Exiv2 library
|
|
|
|
|
|
|
|
|
|
* Added full Iptc read and write support. Thanks to Brad Schick for
|
|
|
|
|
this and a lot more contributions to this release.
|
|
|
|
|
|
|
|
|
|
* Converted Metadatum to an abstract base class, added Exifdatum
|
|
|
|
|
and Iptcdatum classes. Migration of existing programs: Use class
|
|
|
|
|
Exifdatum instead of Metadatum. (Brad Schick)
|
|
|
|
|
|
|
|
|
|
* Added Key, ExifKey and IptcKey class hierarchy. Requires changes
|
|
|
|
|
to existing pograms: Use class ExifKey where plain std::string
|
|
|
|
|
keys were used before (e.g., ExifData::findKey()).
|
|
|
|
|
|
|
|
|
|
* Changed Exif keys to 'Exif.ifdItem.tagName' to be consistent
|
|
|
|
|
with the new Iptc keys. All keys of existing programs need to be
|
|
|
|
|
updated. See the web pages or documentation for the new keys.
|
|
|
|
|
|
|
|
|
|
* Revamped class Image and introduced byte* interface. (Brad Schick)
|
|
|
|
|
|
|
|
|
|
* Added autoconf configure script.
|
|
|
|
|
|
|
|
|
|
* Added MSVC project files. (Brad Schick)
|
|
|
|
|
|
|
|
|
|
* Appended 'Id' to Ifd ids to work around a g++-3.4 problem.
|
|
|
|
|
|
|
|
|
|
* Updated documentation.
|
|
|

Changes from version 0.3 to 0.4
|
|
|
|
|
-------------------------------
|
|
|
|
|
|
|
|
|
|
* Exiv2 utility
|
|
|
|
|
|
|
|
|
|
* Less rigid command line argument parsing: Guess the action from the
|
|
|
|
|
option given and use print as the default action.
|
|
|
|
|
|
|
|
|
|
* Print Nikon makernote values for ISO Speed, Quality and WhiteBalance
|
|
|
|
|
in the summary.
|
|
|
|
|
|
|
|
|
|
* Exiv2 library
|
|
|
|
|
|
|
|
|
|
* Fixed ExifData::copyFromMetadata to automatically add missing
|
|
|
|
|
offset tags. Thanks to Joseph Heled for identifying this bug.
|
|
|
|
|
|
|
|
|
|
* Started to fix MSVC errors and warnings. Thanks to Steven R. King for
|
|
|
|
|
his work to get Exiv2 to compile on MSVC. The task is not yet
|
|
|
|
|
completed but the library should compile without too many warnings.
|
|
|
|
|
|
|
|
|
|
* Added three different Nikon makernote formats.
|
|
|
|
|
|
|
|
|
|
* IfdMakerNote: Replaced too simple prefix with a more general concept
|
|
|
|
|
of a makernote header.
|
|
|
|
|
|
|
|
|
|
* Added the makernote buffer to the arguments passed to the makernote
|
|
|
|
|
create function. This allows the makernote create function to
|
|
|
|
|
determine the exact makernote needed based on its content. The new
|
|
|
|
|
concept is used to automatically determine which of the three Nikon
|
|
|
|
|
makernotes to create.
|
|
|
|
|
|
|
|
|
|
* Fixed MakerNoteFactory::match() to prefer an exact match over a
|
|
|
|
|
wildcard match with the same number of matching characters (Key
|
|
|
|
|
"Nikon" now prefers registry entry "Nikon" over "Nikon*"), simplified
|
|
|
|
|
the return value of match() to an integer score value.
|
|
|
|
|
|
|
|
|
|
* Sigma makernote: Added "FOVEON" and "*" to registry.
|
|
|
|
|
|
|
|
|
|
* Added len argument and boundary checks to various read functions,
|
|
|
|
|
in particular, the IFD read method.
|
|
|
|
|
|
|
|
|
|
* Improved handling of corrupt IFDs: Truncate field if offset points
|
|
|
|
|
outside of the available buffer.
|
|
|
|
|
|
|
|
|
|
* Slightly improved error handling: strError() is now a static member
|
|
|
|
|
of ExifData.
|
|
|
|
|
|
|
|
|
|
* Added exifcomment example program.
|
|
|
|
|
|
|
|
|
|
* Fixed an embarassing bug in ExifData::updateEntries, which caused
|
|
|
|
|
write after erasing metadata to write back the original metadata.
|
|
|
|
|
|
|
|
|
|
* Fixed TypeInfoTable to return invalid if typeId is too large.
|
|
|
|
|
|
|
|
|
|
* Makefile: (un)install targets now only (un)install exiv2.
|
|
|
|
|
|
|
|
|
|
* Code cleanup, documentation updates and miscellaneous bug fixes.
