# Changelog
## Image 0.8.0
This is the changelog for Image version 0.8.0 released on September 30, 2022. For older changelogs please consult the release tag on [GitHub](https://github.com/kipcole9/image/tags)
* `Image.open/2` now accepts raw image data for the image types `.jpeg`, `.png`, `.webp` and `.tiff`
## Image 0.7.0
This is the changelog for Image version 0.7.0 released on September 30, 2022. For older changelogs please consult the release tag on [GitHub](https://github.com/kipcole9/image/tags)
### Enhancements
* Set the environment variable `VIPS_BLOCK_UNTRUSTED` at application start if it is not already set. As of [libvips 8.13](https://www.libvips.org/2022/05/28/What's-new-in-8.13.html) this environment variable will cause `libvips` to not use any image loaders that are "unfuzzed".
* Add mutable draw operations. These operations mutate an image directly and hence special care is taken to avoid race conditions. All mutuable operations are serialized via a `GenServer`. See the `Image.Draw` module. These functions are experimental for now pending additional testing.
* Add `Image.from_binary/2` to support creating an image from a raw binary.
* Thanks to @timothyvanderaerden for the PR to support getting dialyzer under control. Work will continue on this over the next several releases.
## Image 0.6.0
This is the changelog for Image version 0.6.0 released on July 19th, 2022. For older changelogs please consult the release tag on [GitHub](https://github.com/kipcole9/image/tags)
### Bug fixes
* Don't attempt to compile code that refers to `Plug.t` if `Plug` is not configured. Thanks to @kwando. Closes #7.
### Enhancements
* Adds `Image.dshash/1` to return a 512-bit image hash.
* Adds `Image.hamming_distance/2` to compare the similarity of two images or two image hashes.
* Adds `Image.radial_gradient/3` to great a radial gradient image. This could be used to composite over another image to add a vignette.
* Adds `Image.Math` logical functions `boolean_and/2`, `boolean_or/2`, `boolean_xor/2`, `boolean_lshift/2` and `boolean_rshift/2`. Also includes the `!` versions.
* Add operator `use Image.Math` overloads for image `&&&` (`and`), `|||` (`or`), `<<<` (`lshift`) and `>>>` (`rshift`).
## Image 0.5.0
This is the changelog for Image version 0.5.0 released on June 24th, 2022. For older changelogs please consult the release tag on [GitHub](https://github.com/kipcole9/image/tags)
### Enhancements
* Adds `Image.to_nx/1` to convert an image to an Nx tensor.
* Adds `Image.from_nx/1` to convert an Nx tensor into an image.
## Image 0.4.0
This is the changelog for Image version 0.4.0 released on June 23rd, 2022. For older changelogs please consult the release tag on [GitHub](https://github.com/kipcole9/image/tags)
### Enhancements
* Adds support for opening streaming images. This allows images to be streamed from `File.stream!/3` or from any `t:Stream.t/0` including those created from [ExAws.S3](https://hexdocs.pm/ex_aws_s3/ExAws.S3.html) by [ExAws.stream!/2](https://hexdocs.pm/ex_aws/ExAws.html#stream!/2).
* Adds support writing streaming images. This allows images to be streamed as an enumerable which can then be consumed by `Plug.Conn.chunk/2`, by `ExAws.S3.upload/3`, `File.stream/3` or any other function that processes stream resources. See the `test/stream_image_test.exs` for examples.
* Adds a `:memory` option to `Image.write/3`. Instead of a path name or stream, use `:memory` if you'd like to return a `binary` form of an image in its formatted type. Note that this will run the image transformation pipeline resulting in the entire final image being loaded into memory. Therefore this option should be used sparingly since most use cases do not require this option. It is primarily added to facilitate passing images to other libraries in the Elixir ecosystem.
## Image 0.3.0
This is the changelog for Image version 0.3.0 released on June 4th, 2022. For older changelogs please consult the release tag on [GitHub](https://github.com/kipcole9/image/tags)
### Enhancements
* Add `Image.dominant_color/2` to return the dominant color of an image
* Add `Image.histogram/1` to return a histogram of an image
* Add `Image.get_pixel` to get the pixel value at a given `x` and `y` offset into an image.
## Image 0.2.0
This is the changelog for Image version 0.2.0 released on May 18th, 2022. For older changelogs please consult the release tag on [GitHub](https://github.com/kipcole9/image/tags)
### Enhancements
* Adds `Image.Text` to support generating an image from a string. See `Image.Text.text/2`.
* Adds `Image.Shape` to support generating images from shapes. In this release there is a generalised support for polygons and stars. See `Image.Shape.polygon/2` and `Image.Shape.star/2`.
* Improves `Image.compose/3` to support composing with image lists, relative image placement and more.
## Image 0.1.0
This is the changelog for Image version 0.1.0 released on May 4th, 2022. For older changelogs please consult the release tag on [GitHub](https://github.com/kipcole9/image/tags)
### Enhancements
* Initial release
