0.9.1 (2021-07-06)

• Bugfixes
  • Fixed format/2 when saving without extension or saving in place
  • Avoid potential buffer corruption in create/2
  • Windows: Fixed resize_to_limit/2 and faster command invocation

0.9.0 (2021-07-03)

• Breaking changes

  • save/2 and verbose/1 will use convert and identify executables instead of mogrify (except for in_place: true passed to save/2). This fixes issues related to ImageMagick 6.9.12-14 and 7.0.11-13 behavior changes, where the input file would get overwritten.

• Enhancements

  • Added identify/1 which works similarly to verbose/1

• Bugfixes

  • histogram/1 will parse fractional RGB values
  • Input file will no longer be overwritten (except for in_place: true passed to save/2) when using ImageMagick 6.9.12-14 or higher, and ImageMagick 7.0.11-13 or higher

0.8.0 (2020-08-10)

• Breaking changes

  • create/2 and save/2 will throw an error if the ImageMagick command fails

• Enhancements

  • Added configuration options for mogrify and convert executable paths. See README.

0.7.4 (2020-06-08)

• Enhancements
  • Added support for Plasma via custom(image, "plasma", ...) combined with create/2. See README for an example.

0.7.3 (2019-08-19)

• Bugfixes
  • Create intermediate missing directories instead of silently failing save/2 and create/2
  • Fix for custom(image, "annotate", ...) with multi-word text

0.7.0 (2018-12-14)

  • Added Image.buffer field

• Bugfixes

  • Allow nil Image.path with create/2, helps when creating images from scratch with Pango

0.6.1 (2018-05-08)

• Fix histogram/1 for RGBA images

0.6.0 (2018-04-17)

• Breaking changes

  • Requires Elixir 1.2 or higher

0.5.0 (2016-10-14)

• New functions

  • create/2 uses convert CLI tool to create a new image from scratch, without requiring a base image. See mogrify_draw for an example use case.

• Enhancements

  • custom/3 supports "plus-form" arguments, e.g. custom(image, "+raise", 50)

0.4.0 (2016-08-23)

• Breaking changes

  • Image.width and Image.height are now integers instead of binaries

• Enhancements

  • verbose/1 no longer modifies the input file
  • Added Image.frame_count integer field for animated images, set by verbose/1

0.3.3 (2016-08-01)

• verbose/1 now sets the Image.animated field for images containing multiple frames

0.3.2 (2016-06-30)

  • save(image) by default creates a temporary file
  • save(image, in_place: true) gets the old behavior of overwriting the existing file
  • save(image, path: "/some/destination.jpg") lets you specify the path to write the new file

• New functions

  • auto_orient/1 corresponding to mogrify -auto-orient
  • custom/3 letting you run arbitrary commands, for example: custom(image, "gaussian-blur", 5)

• Bugfixes

  • Fixed mix test failures on Windows
  • Avoid dirty Git working directory when running mix test

• Misc

  • Mogrify is now licensed under the MIT License
