Support 32- and 64-bit integer sample grayscale and RGB(A) images
 2019-12-19 13:19:35 +00:00
Andrew Champion abd6aee19f Remove outdate and ambiguous TODO (minor) 2019-12-16 22:10:57 +00:00
Andrew Champion c72a8d364d Add tests for exotic 12-bit sample images 
These images should correctly report their color depths, but fail to
decode as they are unsupported.
 2019-12-16 18:53:44 +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 6e61de81b6 Simplify color type matching 2019-12-11 12:56:11 +00:00
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 15929f8b8e Document changes for release 0.4 
Fixes: #60
 2019-11-21 19:23:03 +01:00
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.
 2019-11-20 19:56:13 +01:00
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.

HeroicKatora 62fee106a7 Merge pull request #62 from onnotechno/multipage_image_patch 
Multipage image patch
 2019-11-12 13:13:57 +01:00
Onno Kammeraad fd789dc420 Cursor::new(Vec::new()) requires a &mut instead of just & 2019-11-12 13:09:09 +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.

OnnoandHeroicKatora f70447325e Update tests/encode_images.rs 
Co-Authored-By: HeroicKatora <HeroicKatora@users.noreply.github.com>
 2019-11-12 10:40:19 +01:00
Onno Kammeraad b2eb480c44 add multipage testcase, to validate the multipage image handling 2019-11-12 09:44:27 +01:00
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 258edf4a46 Remove the num-derive dependency 2019-11-10 18:02:43 +01:00
Andreas Molzer f88c9f00c3 Move everything to the tags macro 2019-11-10 18:02:42 +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.
 2019-11-10 18:02:08 +01:00
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.
