d3b45fae77 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.

d8cdf29fa6 TagIndex: Refactored to prepare for custom tags. 
- More specifically, to prepare the way to register non-standard IFDs
  and tags.

f4db9f31af tags: We now use a singleton TagIndex internally. 
- We now embed the tags data so that we can be used in single,
  distributable binaries..

1c95c159fb ifd_builder: Renamed "FromConfig" functions. 
- ..to use the word "Standard" instead, instead of having both.
- Removed original NewStandardBuilderTag function. Just used by a couple
  of tests and it conflicts with one of the renamings.

4c58c1c84b 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).
 2018-06-06 05:17:56 -04:00
Dustin Oprea

f1b0dd3a32 exif: Streamlined header-builder. 
- The ParseExifHeader() function is now completely responsible for
  header decomposition and offset information.

7745cfe74c exif: Deimplemented IsExif(). 
- exif
  - Began deconstructing Exif type in favor of just defining those
    methods as functions.
  - Added additional tests.
 2018-06-06 04:37:43 -04:00

32664e6098 exif: Streamlined EXIF header parse. Made to behave like IsExif(). 
- We're prepping to deimplement IsExif() because it's just a lame
  duplication of ParseExifHeader().
  - Transitional step to being able to fix incorrect-header problem.

570c4d582c ifd_builder: renamed builderTag to BuilderTag. 
- It's probably a generally good idea.
  - These are usually created by other methods, but they're regularly
    interacted with when you want to make tag changes and by making them
    private we can't public official, testable examples.

- Corrected names for new examples.

8ce7625fc9 ifd_builder_encode: Fixed addressing. 
- Corrects the resolution issue that we were experiencing in sibling
  IFDs.

080ff7d07d Adjusted some string representations. Fixed some hex-encodings. 
- unknown: We no longer truncate UNDEFINED UserComment values.
  - This is one less thing that will be different between what we read
    and how we encode.
 2018-05-28 21:14:15 -04:00

3c1c668a9f encode: We now encode child IFDs as they occur. 
- ..rather than after the normal tags.

5996e32e27 type_encode: Added to-do. 2018-05-25 21:12:45 -04:00

75ff008365 thumbnails: Reimplemented to use normal decode flow. 
- We added a trick to overcome the fact that the tag is a slice of longs
  rather than bytes (and would usually cause check errors and alignment
  problems), but this allows us to use the normal allocation and
  decoding flows that are used by normal tags.
  - Made things simpler, but we're still mis-encoding the
    thumbnail, somehow/somewhere.
 2018-05-25 21:12:24 -04:00

c93f37a85d ifd_enumerate: Now parse and expose thumbnail. 2018-05-24 15:27:45 -04:00
