Dustin Oprea a6301f85c8 README.md: Fix example 
Fixes #61
 2021-06-25 18:48:31 -04:00
Dustin Oprea 8213cfabc6 utility.go: Can now get flat from an RS. Add missing tests. 2021-05-12 01:50:20 -04:00
Dustin Oprea 120bcdb2a5 common/parser.go: Trim ASCII-NUL strings to exclude binary characters 
This is for convenience. We're already ignoring whether it does or does
not have the NUL. Since having binary characters is likely an
undesireable flaw in the image and support for binary characters by EXIF
is probably just a vestigial, ridiculous feature, just stop short and
return the preceding characters if encountered. If we do actually need
the binary at some point in the future, we can circle back and
potentially add an option to do so.

Closes #55

Dustin Oprea d42f8ce9cd tags.go: Add 'universal tags' support 
- This will allow tags to be matched from any IFD if not found in the
  primary and to go with whatever type is encoded into the tag even if
  it disagrees with what is officially supported.

Dustin Oprea 443fda923a common/type.go: Truncate ASCII strings at the first NUL 
This can prevent the string from being classified as "binary" and its
value being suppressed in output.

Dustin Oprea 0d9ceeb35b exif.go: Add support for seeking to multiple EXIF blobs (SearchAndExtractExifN) 
- ifd_enumerate.go
  - Bugfixes for various broken log messages.
  - Bugfix for ErrTagNotFound not actually skipping.

- common/parser.go: Parsing ASCII now panics if there's binary (8-bit)
  characters.
  - utility.go: GetFlatExifData() just logs and skips these.

- exif.go: Add searchAndExtractExifWithReaderWithDiscarded(), to return
  how many bytes it seeks through.

Dustin Oprea 74a1612f20 v3/ifd_enumerate: Skip tags that have a divergent embedded type 
This should mitigate most issues where the same tag appears multiple
times with different types. This happens more than you would think that
it would.

- ErrTagTypeNotValid is now returned unwrapped.
  - This is typically the convention for static error messages.
