In most cases, this is caused by + not enforcing memory limits, though other panics have been seen from fuzzing. +- The color space information of pixels is not clearly communicated. + +## Changes + +### Unreleased + +- More convenient to use buffers will be added in the future. In particular, + improving initialization, passing of output buffers, and adding a more + complete representation for layouts. The plan is for these to interact with + the rest of the library through a byte-based interface similar to + `ImageDecoder`. + See ongoing work on [`image-canvas`](https://github.com/image-rs/canvas) if + you want to participate. + +### Version 0.24.7 + +New features: +- Added `{ImageBuffer, DynamicImage}::write_with_encoder` to simplify writing + images with custom settings. +- Expose ICC profiles stored in tiff and wepb files. +- Added option to set the background color of animated webp images. +- New methods for sampling and interpolation of `GenericImageView`s + +Bug fixes: +- Fix panic on empty dxt. +- Fix several panics in webp decoder. +- Allow unknown chunks at the end of webp files. + +### Version 0.24.6 + +- Add support for QOI. +- ImageDecoders now expose ICC profiles on supported formats. +- Add support for BMPs without a file header. +- Improved AVIF encoder. +- WebP decoding fixes. + +### Version 0.24.5 + +Structural changes: +- Increased the minimum supported Rust version (MSRV) to 1.61. +- Increased the version requirement for the `tiff` crate to 0.8.0. +- Increased the version requirement for the `jpeg` crate to 0.3.0. + +Bug fixes: +- The `as_rgb32f` function of `DynamicImage` is now correctly documented. +- Fixed a crash when decoding ICO images. Added a regression test. +- Fixed a panic when transforming webp images. Added a regression test. +- Added a check to prevent integer overflow when calculating file size for BMP + images. The missing check could panic in debug mode or else set an incorrect + file size in release mode. +- Upgraded the PNG image encoder to use the newer `PngEncoder::write_image` + instead of the deprecated `PngEncoder::encode` which did not account for byte + order and could result in images with incorrect colors. +- Fixed `InsufficientMemory` error when trying to decode a PNG image. +- Fix warnings and CI issues. +- Typos and links in the documentation have been corrected. + +Performance: +- Added check for dynamic image dimensions before resizing. This improves + performance in cases where the image does not need to be resized or has + already been resized. + +### Version 0.24.4 + +New Features: +- Encoding for `webp` is now available with the native library. This needs to + be activate explicitly with the `web-encoder` feature. +- `exr` decoding has gained basic limit support. + +Bug fixes: +- The `Iterator::size_hint` implementation of pixel iterators has been fixed to + return the current length indicated by its `ExactSizeIterator` hint. +- Typos and bad references in the documentation have been removed. + +Performance: +- `ImageBuffer::get_pixel{,_mut}` is now marked inline. +- `resize` now short-circuits when image dimensions are unchanged. + +### Version 0.24.3 + +New Features: +- `TiffDecoder` now supports setting resource limits. + +Bug fixes: +- Fix compile issues on little endian systems. +- Various panics discovered by fuzzing. + +### Version 0.24.2 + +Structural changes: +- CI now runs `cargo-deny`, checking dependent crates to an OSS license list + and against RUSTSEC advisories. + +New Features: +- The WebP decoder recognizes and decodes images with `VP8X` header. +- The DDS decoder recognizes and decodes images with `DX10` headers. + +Bug fixes: +- Calling `DynamicImage`/`ImageBuffer`'s methods `write_to` and `save` will now + work properly even if the backing container is larger than the image layout + requires. Only the relevant slice of pixel data is passed to the encoder. +- Fixed a OOM-panic caused by malformed images in the `gif` decoder. + +### Version 0.24.1 + +Bug Fixes: +- ImageBuffer::get_pixel_checked would sometimes return the incorrect pixel. +- PNG encoding would sometimes not recognize unsupported color. + +### Version 0.24.0 + +Breaking changes + +Structural changes: +- Minimum Rust version is now `1.56` and may change in minor versions until + further notice. It is now tracked in the library's `Cargo.toml`, instead, by + the standard `[package.rust-version]` field. Note: this applies _to the + library itself_. You may need different version resolutions for dependencies + when using a non-stable version of Rust. +- The `math::utils::{nq, utils}` modules have been removed. These are better + served through the `color_quant` crate and the standard library respectively. +- All codecs are now available through `image::codecs`, no longer top-level. +- `ExtendedColorType` and `DynamicImage` have been made `#[non_exhaustive]`, + providing more methods instead of exhaustive matching. +- Reading images through the generic `io::Reader`, as well as generic + convenience interfaces, now requires the underlying reader to be `BufRead + + Seek`. This allows more efficient support more formats. Similarly, writing + now requires writers to be `Write + Seek`. +- The `Bgra*` variants of buffers, which were only half-supported, have been + removed. The owning buffer types `ImageBuffer` and `DynamicImage` + fundamentally already make a choice in supported pixel representations. This + allows for more consistent internal behavior. Callers are expected to convert + formats when using those buffers, which they are required to do in any case + already, and which is routinely performed by decoders. + +Trait reworks: +- The `Pixel` trait is no longer implemented quite as liberally for structs + defined in the crate. Instead, it is now restricted to a set of known channel + which ensures accuracy in computations involving those channels. +- The `ImageDecoderExt` trait has been renamed to `ImageDecoderRect`, according + to its actual functionality. +- The `Pixel` trait and its `Subpixel` field no longer require (or provide) a + `'static` lifetime bound. +- The `Pixel` trait no longer requires specifying an associated, constant + `ColorType`. This was of little relevance to computation but made it much + harder to implement and extend correctly. Instead, the _private_ + `PixelWithColorType` extension is added for interfaces that require a + properly known variant. +- Reworked how `SubImage` interacts with the `GenericImage` trait. It is now a + default implementation. Note that `SubImage` now has _inherent_ methods that + avoid double-indirection, the trait's method will no longer avoid this. +- The `Primitive` trait now requires implementations to provide a minimum and + maximum logical bound for the purpose of converting to other primitive + representations. + +Additions + +Image formats: +- Reading lossless WebP is now supported. +- The OpenEXR format is now supported. +- The `jpeg` decoder has been upgraded to Lossless JPEG. +- The `AvifEncoder` now correctly handles alpha-less images. Some additional + color formats are converted to RGBA as well. +- The `Bmp` codec now decodes more valid images. It can decode a raw image + without performing the palette mapping. It provides a method to access the + palette. The encoder provides the inverse capabilities. +- `Tiff` is now an output format. + +Buffers and Operations: +- The channel / primitive type `f32` is now supported. Currently only the + OpenEXR codec makes full use of it but this is expected to change. +- `ImageBuffer::{get_pixel_checked, get_pixel_mut_checked}` provide panic-free + access to pixels and channels by returning `Option<&P>` and `Option<&mut P>`. +- `ImageBuffer::write_to` has been added, encoding the buffer to a writer. This + method already existed on `DynamicImage`. +- `DynamicImage` now implements `From<_>` for all supported buffer types. +- `DynamicImage` now implements `Default`, an empty `Rgba8` image. +- `imageops::overlay` now takes coordinates as `i64`. + +Limits: +- Added `Limits` and `LimitSupport`, utilized in `io::Reader`. These can be + configured for rudimentary protection against resource exhaustion (images + pretending to require a very large buffer). These types are not yet + exhaustive by design, and more and stricter limits may be added in the + future. +- Encoders that do provide inherent support for limits, or reserve a + significant amount of internal memory, are urged to implement the + `set_limits` extension to `ImageDecoder`. Some strict limit are opt-in, which + may cause decoding to fail if not supported. + +Miscellaneous: +- `PNMSubtype` has been renamed to `PnmSubtype`, by Rust's naming scheme. +- Several incorrectly capitalized `PNM*` aliases have been removed. +- Several `enum` types that had previously used a hidden variant now use the + official `#[non_exhaustive]` attribute instead. + +### Version 0.23.14 + +- Unified gif blending in different decode methods, fixing out-of-bounds checks + in a number of weirdly positioned frames. +- Hardened TGA decoder against a number of malicious inputs. +- Fix forward incompatible usage of the panic macro. +- Fix load_rect for gif reaching `unreachable!()` code. + +- Added `ExtendedColorType::A8`. +- Allow TGA to load alpha-only images. +- Optimized load_rect to avoid unnecessary seeks. + +### Version 0.23.13 + +- Fix an inconsistency in supported formats of different methods for encoding + an image. +- Fix `thumbnail` choosing an empty image. It now always prefer non-empty image + dimensions. +- Fix integer overflow in calculating requires bytes for decoded image buffers + for farbfeld, hdr, and pnm decoders. These will now error early. +- Fix a panic decoding certain `jpeg` image without frames or meta data. +- Optimized the `jpeg` encoder. +- Optimized `GenericImage::copy_from` default impl in various cases. + +- Add `avif` decoders. You must enable it explicitly and it is not covered by + our usual MSRV policy of Rust 1.34. Instead, only latest stable is supported. +- Add `ImageFormat::{can_read, can_write}` +- Add `Frame::buffer_mut` +- Add speed and quality options on `avif` encoder. +- Add speed parameter to `gif` encoder. +- Expose control over sequence repeat to the `gif` encoder. +- Add `{contrast,brighten,huerotate}_in_place` functions in imageproc. + +- Relax `Default` impl of `ImageBuffer`, removing the bound on the color type. +- Derive Debug, Hash, PartialEq, Eq for DynamicImage + +### Version 0.23.12 + +- Fix a soundness issue affecting the impls of `Pixel::from_slice_mut`. This + would previously reborrow the mutable input reference as a shared one but + then proceed to construct the mutable result reference from it. While UB + according to Rust's memory model, we're fairly certain that no miscompilation + can happen with the LLVM codegen in practice. + See 5cbe1e6767d11aff3f14c7ad69a06b04e8d583c7 for more details. +- Fix `imageops::blur` panicking when `sigma = 0.0`. It now defaults to `1.0` + as all negative values. +- Fix re-exporting `png::{CompressionType, FilterType}` to maintain SemVer + compatibility with the `0.23` releases. + +- Add `ImageFormat::from_extension` +- Add copyless DynamicImage to byte slice/vec conversion. +- Add bit-depth specific `into_` and `to_` DynamicImage conversion methods. + + +### Version 0.23.11 + +- The `NeuQuant` implementation is now supplied by `color_quant`. Use of the + type defined by this library is discouraged. +- The `jpeg` decoder can now downscale images that are decoded by 1,2,4,8. +- Optimized the jpeg encoding ~5-15%. +- Deprecated the `clamp` function. Use `num-traits` instead. +- The ICO decoder now accepts an empty mask. +- Fixed an overflow in ICO mask decoding potentially leading to panic. +- Added `ImageOutputFormat` for `AVIF` +- Updated `tiff` to `0.6` with lzw performance improvements. + +### Version 0.23.10 + +- Added AVIF encoding capabilities using the `ravif` crate. Please note that + the feature targets the latest stable compiler and is not enabled by default. +- Added `ImageBuffer::as_raw` to inspect the underlying container. +- Updated `gif` to `0.11` with large performance improvements. + +### Version 0.23.9 + +- Introduced correctly capitalized aliases for some scream case types +- Introduced `imageops::{vertical_gradient, horizontal_gradient}` for writing + simple color gradients into an image. +- Sped up methods iterating over `Pixels`, `PixelsMut`, etc. by using exact + chunks internally. This should auto-vectorize `ImageBuffer::from_pixel`. +- Adjusted `Clone` impls of iterators to not require a bound on the pixel. +- Add `Debug` impls for iterators where the pixel's channel implements it. +- Add comparison impls for `FilterType` + +### Version 0.23.8 + +- `flat::Error` now implements the standard `Error` trait +- The type parameter of `Map` has been relaxed to `?Sized` +- Added the `imageops::tile` function that repeats one image across another + +### Version 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 + +### Version 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`. + +### Version 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`. + +### Version 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` + +### Version 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 + +### Version 0.23.2 + +- The dependency on `jpeg-decoder` now reflects minimum requirements. + +### Version 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 + +### Version 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 (#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`). + +### Version 0.22.5 + +- Added `GenericImage::copy_within`, specialized for `ImageBuffer` +- Fixed decoding of interlaced `gif` files +- Prepare for future compatibility of array `IntoIterator` in example code + +### Version 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`. + +### Version 0.22.3 + +- Added a new module `io` containing a configurable `Reader`. It can replace + the bunch of free functions: `image::{load_*, open, image_dimensions}` while + enabling new combinations such as `open` but with format deduced from content + instead of file path. +- Fixed `const_err` lint in the macro expanded implementations of `Pixel`. This + can only affect your crate if `image` is used as a path dependency. + +### Version 0.22.2 + +- Undeprecate `unsafe` trait accessors. Further evaluation showed that their + deprecation should be delayed until trait `impl` specialization is available. +- Fixed magic bytes used to detect `tiff` images. +- Added `DynamicImage::from_decoder`. +- Fixed a bug in the `PNGReader` that caused an infinite loop. +- Added `ColorType::{bits_per_pixel, num_components}`. +- Added `ImageFormat::from_path`, same format deduction as the `open` method. +- Fixed a panic in the gif decoder. +- Aligned background color handling of `gif` to web browser implementations. +- Fixed handling of partial frames in animated `gif`. +- Removed unused direct `lzw` dependency, an indirect dependency in `tiff`. + +### Version 0.22.1 + +- Fixed build without no features enabled + +### Version 0.22 + +- The required Rust version is now `1.34.2`. +- Note the website and blog: [image-rs.org][1] and [blog.image-rs.org][2] +- `PixelMut` now only on `ImageBuffer` and removed from `GenericImage` + interface. Prefer iterating manually in the generic case. +- Replaced an unsafe interface in the hdr decoder with a safe variant. +- Support loading 2-bit BMP images +- Add method to save an `ImageBuffer`/`DynamicImage` with specified format +- Update tiff to `0.3` with a writer +- Update png to `0.15`, fixes reading of interlaced sub-byte pixels +- Always use custom struct for `ImageDecoder::Reader` +- Added `apply_without_alpha` and `map_without_alpha` to `Pixel` trait +- Pixel information now with associated constants instead of static methods +- Changed color structs to tuple types with single component.
