-This is an initial import of exiv2 (0.7,
-http://home.arcor.de/ahuggel/exiv2) into libextractor.
-
-The current code has the following issues:
-
-* more memory leaks than the rest of LE combined and squared,
- thus cannot be added by default
-* previously generated header file is used (exv_conf.h),
- should be merged with Extractor's config.h where needed;
- unnecessary or bad checks should be eliminated
-* lots of dead code
-* possibly contains code that prints to stdout/stderr
-* not sure if the parser is robust enough (needs testing)

-Library Features:
-+ rename erase* methods that access a file to remove*
-+ add ExifData::erase(tag)
-+ Thumbnail support: set (re-calculate)
-+ operator>> for Value, since we already have read()?
-+ Use size_t where appropriate
-+ Support TIFF type ids
-+ Support for broken IFD makernotes (which have corrupted IFD offsets)
-+ Support non-intrusive deletion of entries from an IFD.
-+ Write an example using low level IFD classes to print summary Exif info
-+ Extended JPEG support (actual resolution of the image)
-+ Implement proper error handling
-+ Complete support to create Exif data from scratch:
- + set thumbnail, write thumbnail tags
-+ Make it possible to force write from metadata (just an optional arg to write?)
-
-+ Make Image::doWriteMetadata do its work in a single pass
-
-+ Revise Image and IptcData+ExifData API (aka turn it inside out)
-+ Add PSD images support (and TIFF, NEF, CRW...)
-+ Add support for XML metadata files
-
-Exiv2 functionality
-+ Add offset to value for hexdump (requires metadata to have an offset)
-
-Bugs:
-+ Handle all Todo's
-+ Cleanup and fix implementation of JpegImage (must be able to read any APP0/1),
- should be able to insert exv into extracted thumbs (usually w/o APP0/1)
-+ Review Image interface. Is it really necessary to have so many functions there?
-+ Review the handling of type ids? What if we encounter type 27 in an IFD?
-+ Rational and other output operators (see Josuttis, p653)
-+ Through ExifData::iterator and Metadatum::operator= it is possible to have
- multiple copies of one metadatum in the metadata container
-+ Checks and non-intrusive updates must be atomic, i.e., not change anything
- if the metadata is not compatible
-+ Review: Exception safety
-+ Review: Ifd1 only at Thumbnail, do we really need Thumbnail::update() ?
-+ Is the hexdump output of exiv2 byte-swapped??
-+ Should JpegImage differ between NO Jpeg comment and an empty Jpeg comment??

- perform such memory management.
- <BR>An external data buffer (not managed by %Ifd) is needed for an instance
- of %Ifd which operates in no memory management mode. The %Ifd will
- maintain only pointers into this buffer.
- <BR> The mode without memory management is used to make "non-intrusive
- write support" possible. This allows writing to Exif data of an image
- without changing the data layout of the Exif data, to maximize chances
- that tag data, which the Exif reader may not understand (e.g., the
- Makernote) remains valid. A "non-intrusive write operation" is the
- modification of tag data without increasing the data size.
-
- @note Use the mode with memory management (the default) if you are unsure
- or if these memory management considerations are of no concern to you.
-
- @note The two different modes imply completely different copy and
- assignment behaviours, with the first resulting in entirely separate

- /*!
- @brief Exif makernote interface
-
- %MakerNote is a low-level container for makernote entries. The ExifData
- container uses makernote entries just like the other Exif metadata. Thus,
- clients can access Exif and makernote tags and their values uniformly
- through the ExifData interface. The role of %MakerNote is very similar to
- that of class Ifd (but makernotes do not need to be in IFD format, see
- below). In addition, it provides %MakerNote specific tag descriptions and
- print functions to interpret the makernote values.
-
- MakerNote holds methods and functionality to
- - read the makernote from a character buffer
- - copy the makernote to a character buffer
- - maintain a list of makernote entries (similar to IFD entries)
- - interpret (print) the values of makernote tags
-
- Makernotes can be added to the system by subclassing %MakerNote and
- registering a create function for the new subclass together with the
- camera make and model (which may contain wildcards) in the
- MakerNoteFactory. Since the majority of makernotes are in IFD format,
- subclass IfdMakerNote is provided. It contains an IFD container and
- implements all interface methods related to the makernote entries. <BR>
-
- To implement a new IFD makernote, all that you need to do is
- - subclass %IfdMakerNote,
- - implement methods to read and check the header (if any) as well as
- clone and create functions,
- - add a list of tag descriptions and appropriate print functions and
- - register the camera make/model and create function in the makernote factory.
- .
- See existing makernote implementations for examples, e.g., CanonMakerNote
- or FujiMakerNote.
-
- Finally, the header file which defines the static variable
- \em register*MakerNote needs to be included from mn.hpp, to ensure that
- the makernote is automatically registered in the factory.

- The method searches the make-model tree for a make and model
- combination in the registry that matches the search key. The search is
- case insensitive (Todo: implement case-insensitive comparisons) and
- wildcards in the registry entries are supported. First the best
- matching make is searched, then the best matching model for this make
- is searched. If there is no matching make or no matching model within
- the models registered for the best matching make, then no makernote
- is created and the function returns 0. If a match is found, the
- function invokes the registered create function and returns an
- auto-pointer to the newly created MakerNote. The makernote pointed to
- is owned by the caller of the function and the auto-pointer ensures
- that it is deleted. The best match is an exact match, then a match is
- rated according to the number of matching characters. The makernote
- buffer is passed on to the create function, which can based on its
- content, automatically determine the correct version or flavour of the
- makernote required. This is used, e.g., to determine which of the
- three Nikon makernotes to create.
-
- @param make Camera manufacturer. (Typically the string from the Exif
- make tag.)
- @param model Camera model. (Typically the string from the Exif
- model tag.)
- @param alloc Memory management model for the new MakerNote. Determines
- if memory required to store data should be allocated and
- deallocated (true) or not (false). If false, only pointers to
- the buffer provided to read() will be kept. See Ifd for more
- background on this concept.
- @param buf Pointer to the makernote character buffer.
- @param len Length of the makernote character buffer.
- @param byteOrder Byte order in which the Exif data (and possibly the
- makernote) is encoded.
- @param offset Offset from the start of the TIFF header of the makernote
- buffer.
