Raw

[NEXT] - Unreleased

  • Bugfix: Stop reducing/simplifying rational values like apertures.
  • Breaking API change/bugfix: The altitude part of GpsInfo is now Optional. This works around an upstream change that caused get_gps_info to return None if altitude was unset, even if lat/long were present. Now lat/long will be returned, but altitude will be None. Altitudes that may have been previously shown as 0.0 will now be None. Calls to set_gps_info will also need updating. Thank you Jonas Hagen for the report and investigation.

v0.10.0 - 2023-01-21

  • New API: new_from_app1_segment allows reading metadata from a buffer.
  • Added support for Windows file paths.
  • Require Rust 1.63 as the minimum supported language version.
  • Adopt 2021 edition of the language.
  • Dependency upgrades.

v0.9.1 - 2020-07-12

  • Fixed build failure on arm32 due to invalid assumptions about int size.
  • Fixed null pointer crash when using get_tag_raw().

v0.9.0 - 2019-11-23

  • Added functionality to get and set log levels, thanks to GitHub user t1ra.

v0.8.0 - 2019-09-02

  • Added operations on metadata thumbnail images.
  • Added way to get raw byte values of metadata.
  • Added methods on preview images. All of these thanks to Jean-Baptiste Daval!
  • Require Rust 1.31 as the minimum supported version (and use 2018 edition).

v0.7.0 - 2018-11-25

  • Added initialize() method for safe multi-threaded use.
  • Dependency upgrades.

v0.6.0 - 2018-02-19

  • Require Rust 1.20 as the minimum supported version to match dependencies.
  • Fixed segfault bug in get_tag_multiple_strings when there are no results.
  • Updated gexiv2-sys internal dependency.

v0.5.0 - 2017-06-21

  • Require Rust 1.8 as the minimum supported version to match dependencies.

v0.4.3 - 2017-06-21

  • Pin version of num-traits to unbreak builds on older rustc versions.

v0.4.2 - 2017-04-11

  • Upgraded gexiv2-sys dependency to 0.7.
  • Replaced num dependency with num-rational for faster builds.

v0.4.1 - 2016-10-04

  • Fix for potential crash due to dereferencing null pointer.

v0.4.0 - 2016-07-21

  • Path operations now accept anything that implements AsRefffi::OsStr, which enables support for path::Paths in addition to strs.
  • Breaking change: Image media types are now represented by an enum instead of magic strings. It is easy to convert between the two forms using ::from().
  • Breaking change: get/set_tag_long() are renamed get/set_tag_numeric().
  • Breaking change: get/set_exif_tag_rational() renamed get/set_tag_rational().
  • Breaking change: get/set_tag_long() now operate on i32 values, not i64.
  • Breaking change: Errors are now wrapped in a new rexiv2::Rexiv2Error type.
  • Breaking change: Results are now using a library-specific alias that fixes all Err() instances as Rexiv2Error.

v0.3.3 - 2016-03-30

  • Dependency cleanup: removed rustc-serialize & bumped gexiv2-sys.
  • Types implement more common useful traits.
  • Documentation improvements, including bundling setup instructions.

v0.3.2 - 2015-09-11

  • Updated to use latest gexiv2-sys FFI declarations.

v0.2.3 - 2015-04-30

  • Library now builds with regular stable rustc.

v0.2.2 - 2015-04-03

  • Updated to work with 1.0.0-nightly (d17d6e7f1 2015-04-02) (Note: not Beta!).
