Image 0.33.0

This is the changelog for Image version 0.32.1 released on June 2nd, 2023. For older changelogs please consult the release tag on GitHub

breaking-changes

Breaking Changes

• Image.dhash/1 now returns a 64-bit hash rather than a 512-bit hash. The original algorithm is intended to return a 64-bit hash so this is both a breaking change and bug fix.

• Fix generation of images from text when autofit: false (the default). In these cases the text image is generated from SVG. The original implementation operated on the basis that the image would be generated with a height and width necessary to contain the text of a given font size. The result is not consistent and is influenced by whether the text has ascenders or desenders. The new implementation creates an SVG container of a size large enough to contain the text at the given font-size and then trims away the background to produce the final result. Thanks to @ilesar for the report. Closes #86. As a result of this fix, existing text-generated images may not now be the same as previous releases.

image-0-32-0

Image 0.32.0

This is the changelog for Image version 0.32.0 released on May 24th, 2023. For older changelogs please consult the release tag on GitHub

bug-fixes

Bug Fixes

• Fix Image.Text.text/2 when the text fill color is black (within a tolerance). When the text image is created, Vix.Vips.Operation.find_trim/2 is called to trim the image assuming a black background. Since the fill color is also black, the resulting trim is 0 pixels wide and 0 pixels high. When then cropping the image, the crop fails because the crop size is invalid. The fix is to not crop if there is no trim detected. Thanks to @tielur for the report. Closes #84.

• Fix specification for Image.compose/3 to remove dialyzer error (and include test case). Thanks to @tielur for the report. Closes #85.

• Fix Image.add_alpha/2 when providing a "color". In fact the value should be an integer in the range 0..255 representing the level of transparency of the alpha band. The function spec, documentation and implementation are now changed to accept only an integer (or the atoms :opaque and :transparent).

enhancements

Enhancements

• Adds Image.from_svg/2 and Image.from_svg!/2 to provide a more discoverable means of creating an image from an SVG string.

image-0-28-0

Image 0.28.0

This is the changelog for Image version 0.28.0 released on April 6th, 2023. For older changelogs please consult the release tag on GitHub

bug-fixes-6

Bug Fixes

• Fixes resizing images with alpha bands. Resizing images with alpha bands requires premultiplying the alpha band into the image and reversing that after resizing.

enhancements-4

Enhancements

• Adds Image.warp_perspective/4 to apply a warp transformation to an image. Thanks very much to @sodapopcan for the PR and collaboration.

• Adds Image.straighten_perspective/3 to apply a warp perspective that straighens the image. It is basically Image.warp_perspective/4 with algorithmically derived destination parameter.

• Adds Image.map/2 which applies a transformation matrix (not a convolution kernel) to an image. A transformation matrix can be returned from Image.transform_matrix/3. These two functions underpin Image.warp_perspective/4.

• Adds Image.crop/2 which is a variation of Image.crop/5 that takes the same format of bounding box as that applied to Image.warp_perspective/4 making it easy to apply a warp transform and then crop to the transformed area. Note that cropping requires that the bounding box be a rectangle, not an arbitrary quadrilateral.

image-0-25-0

Image 0.25.0

This is the changelog for Image version 0.25.0 released on February March 1st, 2023. For older changelogs please consult the release tag on GitHub

behavior-change

Behavior Change

• The default access mode for Image.open/2 is now access: :random in line with libvips native default. Although access: :sequential optimizes for many cases (especially with regard to memory) it resulted in poor developer experience since the error messages when trying to re-use a access: :sequential image are difficult to understand and very difficult to re-interpret in image.

bug-fixes-9

Bug Fixes

• Adds :heic and :avif suffixes to the list of valid suffixes for heif file formats. Thanks to @quentin-bettoum for the PR. Closes #50.

• Allows specifying the option padding: 0 for Image.Text.text/2. Previously this only supported positive integers.

• Fix Image.write/3 documentation. Thanks to @jeregrine for the PR. Closes #62.

enhancements-7

Enhancements

• Update README.md to include updated documentation for installing libvips with Vix.

• Adds :x and :y options to Image.Text.text/2 which allows placing the text on its background in the specified location. :x can be specified as a non-negative integer or one of :left, :right or :center with the default being :center. :y can be specified as a non-negative integer or one of :top, :bottom or :middle with the default being :middle. Thanks to @severian1778 for the issue and collaboration. Closes #44.

• Adds an option :effort to Image.write/3 for :png, :heif, :heic, :avif and :webp images that determines the amount of CPU effort permitted when compressing the image data. Thanks to @quentin-bettoum for the PR. Closes #45.

bug-fixes-27

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.

enhancements-24

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.

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.
