Release 0.23.7 - Iterators over immutable pixels of `ImageBuffer` can now be cloned - Added a `tga` encoder - Added `ColorMap::lookup`, an optional reversal of the map - The `EncodableLayout` trait is now exported sha256sum: a2397fc43bd5648b7117aabb3c5e62d0e62c194826ec77b0b4d0c41e62744635 target/package/image-0.23.7.crate
Release 0.23.6 - Added `png::ApngDecoder`, an adapter decoding the animation in an APNG. - Fixed a bug in `jpeg` encoding that would darken output colors. - Added a utility constructor `FlatSamples::with_monocolor`. - Added `ImageBuffer::as_flat_samples_mut` which is a mutable variant of the existing ffi-helper `ImageBuffer::as_flat_samples`. sha256sum: b5b0553fec6407d63fe2975b794dfb099f3f790bdc958823851af37b26404ab4 target/package/image-0.23.6.crate
Release 0.23.5 - The `png` encoder now allows configuring compression and filter type. The output is not part of stability guarantees, see its documentation. - The `jpeg` encoder now accepts any implementor of `GenericImageView`. This allows images that are only partially present in memory to be encoded. - `ImageBuffer` now derives `Hash`, `PartialEq`, `Eq`. - The `Pixels`/`PixelsMut` iterator no longer yields out-of-bounds pixels when the underlying buffer is larger than required. - The `pbm` decoder correctly decodes ascii data again, fixing a regression where it would use the sample value `1` as white instead of `255`. - Fix encoding of RGBA data in `gif` frames. - Constructing a `Rows`/`RowsMut` iterator no longer panics when the image has a width or height of `0`. sha256sum: d534e95ad8b9d5aa614322d02352b4f1bf962254adcf02ac6f2def8be18498e8 target/package/image-0.23.5.crate
Release 0.23.4 - Improved the performance of decoding animated gifs - Added `crop_imm` which functions like `crop` but on a shared reference - The gif `DisposalMethod::Any` is treated as `Keep`, consistent with browsers - Most errors no longer allocate a string, instead implement Display. - Add some implementations of `Error::source` sha256sum: 9117f4167a8f21fa2bb3f17a652a760acd7572645281c98e3b612a26242c96ee target/package/image-0.23.4.crate
Release 0.23.3 - Added `ColorType::has_alpha` to facilitate lossless conversion - Recognize extended WebP formats for decoding - Added decoding and encoding for the `farbfeld` format - Export named iterator types created from various `ImageBuffer` methods - Error in jpeg encoder for images larger than 65536 pixels, fixes panic sha256sum bfc5483f8d5afd3653b38a196c52294dcb239c3e1a5bade1990353ea13bcf387 target/package/image-0.23.3.crate
Release 0.23.1 - Fix cmyk_to_rgb (jpeg) causing off by one rounding errors. - A number of performance improvements for jpeg (encode and decode), bmp, vp8 - Added more details to errors for many formats sha256sum: 403f0c29211dc50a78eb53eeeae87945d44cb63071881834212f36677fccb2b4 target/package/image-0.23.1.crate
Release 0.23.0
This major release intends to improve the interface with regards to handling of
color format data and errors for both decoding and encoding. This necessitated
many breaking changes anyways so it was used to improve the compliance to the
interface guidelines such as outstanding renaming.
It is not yet perfect with regards to color spaces but it was designed mainly
as an improvement over the current interface with regards to in-memory color
formats, first. We'll get to color spaces in a later major version.
- Heavily reworked `ColorType`:
- This type is now used for denoting formats for which we support operations
on buffers in these memory representations. Particularly, all channels in
pixel types are assumed to be an integer number of bytes (In terms of the
Rust type system, these are `Sized` and one can crate slices of channel
values).
- An `ExtendedColorType` is used to express more generic color formats for
which the library has limited support but can be converted/scaled/mapped
into a `ColorType` buffer. This operation might be fallible but, for
example, includes sources with 1/2/4-bit components.
- Both types are non-exhaustive to add more formats in a minor release.
- A work-in-progress (image-rs#1085) will further separate the color model from the
specific channel instantiation, e.g. both `8-bit RGB` and `16-bit BGR`
are instantiations of `RGB` color model.
- Heavily rework `ImageError`:
- The top-level enum type now serves to differentiate cause with multiple
opaque representations for the actual error. These are no longer simple
Strings but contains useful types. Third-party decoders that have no
variant in `ImageFormat` have also been considered.
- Support for `Error::source` that can be downcast to an error from a
matching version of the underlying decoders. Note that the version is not
part of the stable interface guarantees, this should not be relied upon
for correctness and only be used as an optimization.
- Added image format indications to errors.
- The error values produced by decoder will be upgraded incrementally. See
something that still produces plain old String messages? Feel free to
send a PR.
- Reworked the `ImageDecoder` trait:
- `read_image` takes an output buffer argument instead of allocating all
memory on its own.
- The return type of `dimensions` now aligns with `GenericImage` sizes.
- The `colortype` method was renamed to `color_type` for conformity.
- The enums `ColorType`, `DynamicImage`, `imageops::FilterType`, `ImageFormat`
no longer re-export all of their variants in the top-level of the crate. This
removes the growing pollution in the documentation and usage. You can still
insert the equivalent statement on your own:
`use image::ImageFormat::{self, *};`
- The result of `encode` operations is now uniformly an `ImageResult<()>`.
- Removed public converters from some `tiff`, `png`, `gif`, `jpeg` types,
mainly such as error conversion. This allows upgrading the dependency across
major versions without a major release in `image` itself.
- On that note, the public interface of `gif` encoder no longer takes a
`gif::Frame` but rather deals with `image::Frame` only. If you require to
specify the disposal method, transparency, etc. then you may want to wait
with upgrading but (see next change).
- The `gif` encoder now errors on invalid dimensions or unsupported color
formats. It would previously silently reinterpret bytes as RGB/RGBA.
- The capitalization of `ImageFormat` and other enum variants has been
adjusted to adhere to the API guidelines. These variants are now spelled
`Gif`, `Png`, etc. The same change has been made to the name of types such as
`HDRDecoder`.
- The `Progress` type has finally received public accessor method. Strange that
no one reported them missing.
- Introduced `PixelDensity` and `PixelDensityUnit` to store DPI information in
formats that support encoding this form of meta data (e.g. in `jpeg`).

Release 0.22.4 - Added in-place variants for flip and rotate operations. - The bmp encoder now checks if dimensions are valid for the format. It would previously write a subset or panic. - Removed deprecated implementations of `Error::description` - Added `DynamicImage::into_*` which convert without an additional allocation. - The PNG encoder errors on unsupported color types where it had previously silently swapped color channels. - Enabled saving images as `gif` with `save_buffer`. sha256sum: 53cb19c4e35102e5c6fb9ade5e0e236c5588424dc171a849af3141bf0b47768a target/package/image-0.22.4.crate
