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.
