Andrew Champion 959254aee9 Deduplicate encoding tests 
Also removes dev dependency on tempfile.

Andrew Champion abd6aee19f Remove outdate and ambiguous TODO (minor) 2019-12-16 22:10:57 +00:00
Andrew Champion e5d2e7862c Parse all homogeneous bit depth RGB(A) color types 
Make the behavior of RGB and RGBA like Gray in returning ColorTypes for
all homogeneous bit depths, even if those depths are not 8, 16, 32 or
64. Note that this does not change which color types can actually be
decoded.

Andrew Champion 8c4cea5d97 Support 64-bit encoding 
Note that this adds the LONG8 data type from BigTIFF because of bounds
requiring TiffValue. However, this datatype should not actually be
written to tags.

Andreas Molzer f13492e41d Fix a doc typo found in PR review 2019-11-21 18:46:55 +01:00
Andreas Molzer 1d9944c5c5 Mark both detailed error types as non-exhaustive 
This makes it cheaper to introduce new features that might require
amending the list of variants by allowing us to introduce previously
uncovered causes or more specialized representations.
 2019-11-20 20:58:45 +01:00
Andreas Molzer a14b23473b Export the inflate error publicly 
It encapsulates the implementation detail of holding a miniz_oxide
status within. The derived traits are not too extensive for other
possible representations as well.
 2019-11-20 20:02:55 +01:00
Andreas Molzer 101940335c Fix public constructor from miniz_oxide status 
Avoids leaking the dependency on `miniz_oxide` into the public interface
by making a constructor taking a status argument crate internal. It
would otherwise not be possible to replace the deflate decoder without
breaking that interface.

HeroicKatora 8e1c67ee53 Merge pull request #63 from image-rs/tagged 
Replace FromPrimitive with our own tag macro
 2019-11-12 20:14:25 +01:00
Andreas Molzer 7b672998db Get rid of num-traits crate 
Turns out the only use was as a private bound which was unused within
that method.
 2019-11-12 20:06:02 +01:00
Andreas Molzer 07e8501ad6 Prefer matching over if-else-chain in tags macro 
Thanks to the review comment for pointing this style issue out.

Onno Kammeraad 686e9b2648 added a missing offset increase while adding padding 2019-11-11 16:15:01 +01:00
Andreas Molzer 517638a38f Prefer explicit conversion over as 
The discriminant of some enum types can be retrieved with the `as`
operator and in C style enums it is also possible to set a specific
discriminant. However, that may silently change—breaking the value
written to the file. It is better to use that technique mostly for ffi
purposes.

Andreas Molzer a6696ab02f fixup! Move everything to the tags macro 2019-11-10 19:24:22 +01:00

Andreas Molzer f80f4a06d5 Make the Unknown field optional 
Several other uses that currently rely on num-traits for conversion have
no Unknown representation. Thus, the converter now outputs only known
variants or an error and the exposing function then can put the error
value into an Unknown variant instead.

Onno Kammeraad cbae42ea94 fixed support for multipage images, the IDF offset is added during the new and also at the end of the internal_finish. This should only be done once 2019-11-06 14:04:18 +01:00
Onno Kammeraad 80b8ec5cdb Somehow the current offset was invalid when using multipage images. Now using the seek function to get the current offset 2019-11-06 13:58:29 +01:00
Andreas Molzer ffdeb62b9f Rework the tag macro to make it reusable 
Factor out parts that are unique to instantiations such as the name, the
documentation, the underlying type, the public conversion methods.

Also adds the ability to document individual items and remodels the
syntax to more closely resemble ordinary enum definitions.
