更新libclamav库1.0.0版本
2023-01-14 18:28:39 +08:00
# Version 0.8.0
Changes:
* The minimum supported rust version is now indicated in `Cargo.toml`.
* The enums `TiffFormatError` and `TiffUnsupportedError` are now
marked with the `#[non_exhaustive]` attribute.
* Additionally, tag related enums `Value`, `Tags`, `Type`, `CompressionMethod`,
`PhotometricInterpretation`, `PlanarConfiguration`, `Predictor`,
`ResolutionUnit`, `SampleFormat` are also changed.
Removals:
* Removed deprecated methods of `Decoder`: `init`, `read_jpeg`,
`read_strip_to_buffer`, `read_strip`, `read_tile`. The implicit chunk (row or
tile) index order could not be easily tracked by the caller. New separate
utility interfaces may be introduced at a later point, for now callers are
obligated to choose their own.
Fixes:
* Update to `jpeg_decoder = 0.3`.
# Version 0.7.4
New features:
* Creating an encoder for invalid, zero-sized images is now rejected.
Fixes:
* Fix panic, in a case where decoding jpeg encoded images did not expect the
jpeg decoder to return an error.
* Fix panic by validating `rows_per_strip` better, fixing a division-by-zero.
# Version 0.7.3
New features:
* Allow decoder to access specific tiles by index.
* Add support for floating point predictor.
* Tiled jpeg file support.
Changes:
* Various refactoring and performance improvements.
# Version 0.7.2
New features:
* Encoding with `ImageEncoder` now takes an optional compressor argument,
allowing compressed encoding. See the methods
`TiffEncoder::{new_image,write_image}_with_compression`.
* `jpeg_decoder` has been upgraded, now supports lossless JPEG.
Changes:
* Decoding now more consistently reads and interprets the initial IFD, instead
of performing _some_ interpretation lazily. (This change prepares fully lazy
and backwards seeking.)
# Version 0.7.1
New features:
* Encoding signed integer formats is now supported.
* Extensive fuzzing with `cargo fuzz`.
Changes:
* Tile decoding should be a little faster, requires one less intermediate buffer.
* Images whose IFDs form a cycle due to their offsets will now raise an error
when the cycle would be entered (jumping back should still be supported).
Fixes:
* Fixed a regression that caused conflict between strips and tile images,
causing errors in decoding some images.
* Use checked integer arithmetic in limit calculations, fixes overflows.
* IFD Tags are now always cleared between images.
* Found by fuzzing: Several memory limit overflows; JPEG now correctly
validates offsets and a minimum size of its table; Check upper limit of strip
byte size correctly;
Notes:
Our CI has warned that this version no longer builds on `1.34.2` out of the
box. We're still committed to the MSRV on this major version yet one
dependency—`flate2`—has already bumped it in a SemVer compatible version of its
own. This is out-of-our-control (cargo's dependency resolution does not allow
us to address this in a reasonable manner).
This can be address this by pinning the version of `flate2` to `1.0.21` in your
own files. However, you should understand that this puts you in considerable
maintenance debt as you will no longer receive any updates for this dependency
and any package that _requires_ a new version of the `1.0` series would be
incompatible with this requirement (cargo might yell at you very loudly).
# Version 0.7.0
New features:
* Support for encoding BigTiff ([#122](https://github.com/image-rs/image-tiff/pull/122))
* _Breaking:_ Encoder types now have a generic parameter to differentiate BigTiff and standard Tiff encoding. Defaults to standard Tiff.
* Basic tile decoding ([#125](https://github.com/image-rs/image-tiff/pull/125))
* _Breaking:_ There is a new `TiffError::UsageError` variant.
* Support for datatypes `Int8` and `Int16` ([#114](https://github.com/image-rs/image-tiff/pull/114))
* _Breaking:_ `DecodingResult` and `DecodingBuffer` have the two new variants `I8` and `I16`.
* Support for `i32` arrays ([#118](https://github.com/image-rs/image-tiff/pull/118/files))
* _Breaking:_ `DecodingResult` and `DecodingBuffer` have a new `I32` variant.
* Support for `Ifd` and `IfdBig` tag types and `I64` data type ([#119](https://github.com/image-rs/image-tiff/pull/119))
* _Breaking:_ `DecodingResult` and `DecodingBuffer` have a new `I64` variant.
* Add `SMinSampleValue` and `SMaxSampleValue` ([#123](https://github.com/image-rs/image-tiff/pull/123))
Changes:
* Improve deflate support ([#132](https://github.com/image-rs/image-tiff/pull/132))
* Switch to streaming decompression via `flate2`. Aside from performance improvements and lower RAM consumption, this fixes a bug where `max_uncompressed_length` was precalculated for a single tile but then used as a hard limit on the whole data, failing to decompress any tiled images.
* Add support for new `Deflate` tag in addition to `OldDeflate`.
* _Breaking:_ Remove `InflateError`, which is no longer needed with `flate2` ([#134](https://github.com/image-rs/image-tiff/pull/134))
* _Breaking:_ Support for `MinIsWhite` is restricted to unsigned and floating
point values. This is expected to be be re-added once some contradictory
interpretation regarding semantics for signed values is resolved.
Fixes:
* Validate that ASCII tags are valid ASCII and end with a null byte ([#121](https://github.com/image-rs/image-tiff/pull/121))
Internal:
* Simplify decompression logic ([#126](https://github.com/image-rs/image-tiff/pull/126))
* Simplify `expand_strip` ([#128](https://github.com/image-rs/image-tiff/pull/128))
# Version 0.6.1
New features:
* Support for reading `u16` and ascii string tags.
* Added `Limits::unlimited` for disabling all limits.
* Added `ImageEncoder::rows_per_strip` to overwrite the default.
Changes:
* The default strip size for chunked encoding is now 1MB, up from 8KB. This
should lead to more efficient decoding and compression.
Fixes:
* Fixed a bug where LZW compressed strips could not be decoded, instead
returning an error `Inconsistent sizes encountered`.
* Reading a tag with a complex type and a single value returns the proper Value
variant, instead of a vector with one entry.
# Version 0.6.0
New features:
* Support for decoding BigTIFF with 64-bit offsets
* The value types byte, `f32`, `f64` are now recognized
* Support for Modern JPEG encoded images
Improvements:
* Better support for adding auxiliary tags before encoding image data
* Switched to lzw decoder library `weezl` for performance
* The `ColorType` trait now supports `SAMPLE_ENCODING` hints
Fixes:
* Fixed decoding of inline ASCII in tags
* Fixed handling after null terminator in ASCII data
* Recognize tile and sample format tags
# Version 0.5.0
* Added support for 32-bit and 64-bit decoded values.
* Added CMYK(16|32|64) color type support.
* Check many internal integer conversions to increase stability. This should
only lead to images being reported as faulty that would previously silently
break platform limits. If there are any false positives, please report them.
* Remove an erroneous check of decoded length in lzw compressed images.
# Version 0.4.0
* Several enumerations are now non_exhaustive for future extensions.
These are `Tag`, `Type`, `Value`, `PhotometricInterpretation`,
`CompressionMethod`, `Predictor`.
* Enums gained a dedicated method to convert to their TIFF variant value with
the specified type. Performing these conversions by casting the discriminant
with `as` is not guaranteed to be stable, except where documented explicitly.
* Removed the num-derive and num dependencies.
* Added support for decoding `deflate` compressed images.
* Make the decoder `Limits` customizable by exposing members.
* Fixed multi-page TIFF encoding writing incorrect offsets.
