[dependabot]

Release notes

Sourced from image's releases.

Image version 0.72.0

Changed

• Breaking: Unifies background handling under a single :background option across Image.embed/4, Image.flatten/2, Image.join/2, Image.rotate/3 and the affine family (Image.affine/3, Image.translate/4, Image.shear/4, Image.warp_perspective/4), replacing the previous :background_color and :background_transparency options. Set a transparent or semi-transparent fill by wrapping any color as {color, alpha: a}. Thanks to @​hlindset for the PR.

• Breaking: An omitted or nil :background now defers to libvips' native fill everywhere (transparent for alpha images, black otherwise, paper-white in CMYK), so Image.flatten/2 with no background matches how Image.write/3 flattens. Previously Image.flatten/2 and an alpha Image.embed/4 defaulted to opaque black.

Removed

• Breaking: Removes the :black and :white extend modes from Image.embed/4 and narrows the affine-family :extend_mode to :background | :copy; combining a content extend mode with an explicit :background now errors. Use an explicit :background color in place of the removed modes. Thanks to @​hlindset for the PR.

Fixed

• Fix numeric array save options (for example background: [0, 128, 0]) being silently dropped on :memory and stream writes; the filename suffix joined array values with : rather than spaces, which libvips ignores. Thanks to @​hlindset for the PR.

Image version 0.71.0

Added

• Adds ### Examples doctest sections to more than 220 public functions across Image and its submodules. All examples run as doctests.

• Adds a range argument (:limited or :full) to the Image.YUV encode and decode functions, and Image.YUV.valid_ranges/0. :limited (studio-swing) is the default and matches the previous behaviour.

Fixed

• Fix Image.YUV to use studio-swing (limited range) coefficients in both directions by default. Previously the encoder was studio-swing but the decoder was full-range, so YUV round trips compressed colors toward grey.

Removed

• Removes the unused internal modules Image.Nx, Image.Exif.ReadError and Image.Exif.FieldNames. These were private implementation modules with no callers.

Image version 0.70.0

Added

• Adds Image.Lqip.Css to encode an image as a packed LQIP CSS placeholder value, with a new guide including the copy-and-paste stylesheet. Thanks to @​hlindset for the PR.

• Adds Image.BackgroundColor to resolve background color specifications (including :average) into concrete pixels; used by Image.rotate/3, affine and warp operations. Thanks to @​hlindset for the PRs.

• Adds :background color resolution to Image.write/3 so alpha images flatten onto a resolved background when writing to formats without alpha. Thanks to @​hlindset for the PR.

• Adds Image.YUV.valid_encodings/0 and Image.YUV.valid_colorspaces/0.

Changed

• Image.average/1 now weights the average by the alpha band so transparent pixels do not contribute; fully transparent images fall back to the unweighted color-band average, and float-format images return unrounded averages.

• All validation and libvips errors are now returned as {:error, %Image.Error{}} as t:Image.error/0 documents; previously many paths returned bare strings.

• Image.to_nx/2 with shape: :whc now performs a true transpose; Image.from_nx/1 interprets unnamed tensors as {height, width, bands} and narrows 64-bit integer tensors to 32 bits.

• Image.circle/2 center-crops non-square images and merges an existing alpha band instead of adding a second one.
