Image 0.15.0

This is the changelog for Image version 0.15.0 released on Decmber 4th, 2022. For older changelogs please consult the release tag on GitHub

bug-fixes-1

Bug Fixes

• Fix Image.minimize_metadata/1 which was previously creating malformed exif data.

enhancements-1

Enhancements

• Add :autofit option to Image.Text.text/2. When set to true, text is rendered with Vix.Vips.Operation.text/2. The default, false, uses SVG rendering. There are pros and cons to both strategies. The main difference is that autofit: true will automatically size the text and perform line wrapping to fit the specified :width and :height. Thanks to @dmitriid for the suggestion!

• Fixes the rbga color model for integer alpha values (which are automatically cast to the appropriate float value). Thanks to @andreyuhai for your patience and collaboration while this was sorted out.

breaking-change

Breaking change

• Image.resize/3 renamed to Image.thumbnail/3

bug-fixes-8

Bug fixes

• Fix Image.open/2 when opening JPEG images from a binary. Seems JPEG files agree on the <<0xff, 0xd8, 0xff>> header for the first three bytes. But not completely consistent with the following bytes.

• Fix options for Image.Draw functions which are expected to be a map after validation (but were a keyword list).

enhancements-3

• Add Image.QRcode.encode/1 and Image.QRcode.decode/1.

• Add Image.resize/3.

• Add Image.split_bands/1.

• Add Image.if_then_else/3.

• Add Image.preview/1 (and Image.p/1 that delegates to it) to preview an image inline in an iTerm2 terminal windows.

This is the changelog for Image version 0.11.0 released on October 8th, 2022. For older changelogs please consult the release tag on GitHub

image-0-10-0

Image 0.10.0

This is the changelog for Image version 0.10.0 released on October 5th, 2022. For older changelogs please consult the release tag on GitHub

bug-fixes-9

Bug Fixes

• Since the mix build process does a File.cwd!/1 to the directory of each dependency we can't use the dirname of the dependency to decide whether to configure :evision or not. The strategy is now changed to configure :evision only if the environment CONFIGURE_EVISION is set. Note this is only relevant when developing :image itself. Consumers of the library should add :evision as a dependency manually in their application mix.exs as described in the readme. Thanks to @martosaur for the report. Closes #13.

image-0-9-0

Image 0.9.0

This is the changelog for Image version 0.9.0 released on October 1st, 2022. For older changelogs please consult the release tag on GitHub

enhancements-6

Enhancements

• Image.open/2 supports opening .gif and .tif images from raw binary data in addition to the previous .jpeg, .png and .webp.

• Add Image.shape/1

• Add Image.interpretation/1

• Add Image.type/1

• Add initial support for eVision. In this release the function Image.QRcode.decode/1 is provided to decode images that contain a QRcode. See the eVision repository for installation instructions since this library is not yet on hex.pm.

• Removed most dialyzer warnings. The remaining warnings require an update to Vix (a PR has been submitted).

image-0-8-0

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

enhancements-7

Enhancements

image-0-7-0

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

enhancements-8

Enhancements

• Set the environment variable VIPS_BLOCK_UNTRUSTED at application start if it is not already set. As of libvips 8.13 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

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

bug-fixes-10

Bug fixes

• Don't attempt to compile code that refers to Plug.t if Plug is not configured. Thanks to @kwando. Closes #7.

enhancements-9

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

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

enhancements-10

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

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

enhancements-11

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 by ExAws.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.
