Rewired to use IFD-path strings instead of IfdIdentities.
...
- These are absolute representations of where an IFD is positioned with
respect to the other IFDs. There is a more-specific, "fully-qualified"
form of the IFD-path that allows you to express indices in order to
refer to specific siblings.
- Eliminates issues with IFDs at different levels potentially having the
same name (if that's what is required with a certain dataset/
datasource).
- There is a specific IFD registry that controls the heirarchy of IFDs
that we recognize and the tags associated with the child IFDs. This
allows custom hierarchies replacing even the TIFF specification for
which are expected in an image (so we can read other types of images
or any potential IFD hierarchy, even non-image ones).
- IFD and IB instances embed the IFD-path and FQ IFD-path that they were
found or built for.

We now have to pass a specific tag-index in from the top.
...
- This will allow us to handle custom tags and, with a little more work,
custom IFDs.

tags: We now use a singleton TagIndex internally.
...
- We now embed the tags data so that we can be used in single,
distributable binaries..

exif: Eliminated an offset constant. Just used for tests.
...
- Will simplify fixing the header issues we have. It's relative, any way
(won't be affected by the imminent changes to the header).

exif: Deimplemented IsExif().

- Began deconstructing Exif type in favor of just defining those
methods as functions.
- Added additional tests.

ifd_builder: Implemented NewBuilderTagFromConfig() BT factory for testing.
...
- Updated IfdByteEncoder tests to use it instead of hacking-together
their own BT's (makes for more standardized, consistent testing).
- Universally refactored all core IFD knowledge implemented upon a
single IFD name to instead work with IfdIdentity instances, instead,
in order to validate that we only recognize the IFDs only in the
context of the correct parents in the hierarchy.
- Implemented standard testing byte-order (assigned to
TestDefaultByteOrder).
2018-04-27 03:42:59 -04:00

ifd_enumerate: Added tests.
...
- Refactored (IfdTagEntry).ValueBytes() to handle managed undefined
values.
2018-04-22 02:35:33 -04:00
f1f23dca82
General intuitivity refactor. Imp'd (IfdTagEntry).ValueBytes().
...
- Added some assertions and constants. Renamed from variable so it'd be easy to
tell if the byte-arrays, even though they come directly from the EXIF, which
specific offsets they start at (so no remove for confusion during enumeration
and building).
2018-04-21 20:54:56 -04:00

type_decode: Implemented immediate remaining 'unknown'-type tags.
...
- Except for MakerNote. We're just going to have to skip that when
writing, for now.

- We still need to implement the size calculations and tag encoding.
2018-04-20 11:45:32 -04:00
f99faad160
builder: Added full IFD-building functionality.
...
- There are still some placeholders for things that we need to figure
out.
