The decoder now enforces that standard chunks - such as palette, gamma, … occur at most once as specified. -* Added `#[forbid(unsafe_code)]` again. This may come at a minor performance - cost when decoding ASCII text for now. -* Fixed a bug where decoding of large chunks (>32kB) failed to produce the - correct result, or fail the image decoding. As new chunk types are decoded - this introduced regressions relative to previous versions. - -## 0.17.3 - -* Fixed a bug where `Writer::finish` would not drop the underlying writer. This - would fail to flush and leak memory when using a buffered file writers. -* Calling `Writer::finish` will now eagerly flush the underlying writer, - returning any error that this operation may result in. -* Errors in inflate are now diagnosed with more details. -* The color and depth combination is now checked in stream decoder. - -## 0.17.2 - -* Added support for encoding and decoding tEXt/zTXt/iTXt chunks. -* Added `Encoder::validate_sequence` to enable validation of the written frame - sequence, that is, if the number of written images is consistent with the - animation state. -* Validation is now off by default. The basis of the new validation had been - introduced in 0.17 but this fixes some cases where this validation was too - aggressive compared to previous versions. -* Added `Writer::finish` to fully check the write of the end of an image - instead of silently ignoring potential errors in `Drop`. -* The `Writer::write_chunk` method now validates that the computed chunk length - does not overflow the limit set by PNG. -* Fix an issue where the library would panic or even abort the process when - `flush` or `write` of an underlying writer panicked, or in some other uses of - `StreamWriter`. - -## 0.17.1 - -* Fix panic in adaptive filter method `sum_buffer` - -## 0.17.0 - -* Increased MSRV to 1.46.0 -* Rework output info usage -* Implement APNG encoding -* Improve ergonomics of encoder set_palette and set_trns methods -* Make Info struct non-exhaustive -* Make encoder a core feature -* Default Transformations to Identity -* Add Adaptive filtering method for encoding -* Fix SCREAM_CASE on ColorType variants -* Forbid unsafe code - -## 0.16.7 - -* Added `Encoder::set_trns` to register a transparency table to be written. - -## 0.16.6 - -* Fixed silent integer overflows in buffer size calculation, resulting in - panics from assertions and out-of-bounds accesses when actually decoding. - This improves the stability of 32-bit and 16-bit targets and make decoding - run as stable as on 64-bit. -* Reject invalid color/depth combinations. Some would lead to mismatched output - buffer size and panics during decoding. -* Add `Clone` impl for `Info` struct. - -## 0.16.5 - -* Decoding of APNG subframes is now officially supported and specified. Note - that dispose ops and positioning in the image need to be done by the caller. -* Added encoding of indexed data. -* Switched to `miniz_oxide` for decompressing image data, with 30%-50% speedup - in common cases and up to 200% in special ones. -* Fix accepting images only with consecutive IDAT chunks, rules out data loss. - -## 0.16.4 - -* The fdAT frames are no longer inspected when the main image is read. This - would previously be the case for non-interlaced images. This would lead to - incorrect failure and, e.g. an error of the form `"invalid filter method"`. -* Fix always validating the last IDAT-chunks checksum, was sometimes ignored. -* Prevent encoding color/bit-depth combinations forbidden by the specification. -* The fixes for APNG/fdAT enable further implementation. The _next_ release is - expected to officially support APNG. - -## 0.16.3 - -* Fix encoding with filtering methods Up, Avg, Paeth -* Optimize decoding throughput by up to +30% - -## 0.16.2 - -* Added method constructing an owned stream encoder. - -## 0.16.1 - -* Addressed files bloating the packed crate - -## 0.16.0 - -* Fix a bug compressing images with deflate -* Address use of deprecated error interfaces - -## 0.15.3 - -* Fix panic while trying to encode empty images. Such images are no longer - accepted and error when calling `write_header` before any data has been - written. The specification does not permit empty images. - -## 0.15.2 - -* Fix `EXPAND` transformation to leave bit depths above 8 unchanged - -## 0.15.1 - -* Fix encoding writing invalid chunks. Images written can be corrected: see - https://github.com/image-rs/image/issues/1074 for a recovery. -* Fix a panic in bit unpacking with checked arithmetic (e.g. in debug builds) -* Added better fuzzer integration -* Update `term`, `rand` dev-dependency -* Note: The `show` example program requires a newer compiler than 1.34.2 on - some targets due to depending on `glium`. This is not considered a breaking - bug. - -## 0.15 - -Begin of changelog |
