no issue
- This adds the possibility to format AVIF files in Ghost if requested.
- This format is supported in Sharp
- Provides smaller file sizes than webp
refs https://github.com/TryGhost/Team/issues/1652
refs https://github.com/TryGhost/Ghost/issues/13319
- Added support for animated webp and gifs optimization and resizing
- Added optinal `format` option to `unsafeResizeFromBuffer` and `resizeFromBuffer`. E.g. allows you to convert a .svg file to a .png.
- Added optional `animated` option to `unsafeResizeFromBuffer` and `resizeFromBuffer`. Defaults to 'maintain animation'.
- Added optional `withoutEnlargement` option to `unsafeResizeFromBuffer` and `resizeFromBuffer`. Defaults to true. Required to increase SVG size.
- Removed gif and svg from `canTransformFileExtension`. They are supported by sharp now.
- Added `shouldResizeFileExtension` method, which returns if we should resize an image. This is required to prevent resizing SVG files (while it is supported, it is not desired), while allowing them to be converted to PNG (thats why a new method was needed).
- Added `canTransformToFormat` to validate the `format` option.
- Improved TS/JSDoc type inheritance when `makeSafe` is used.
refs https://sharp.pixelplumbing.com/api-utility#cache
- Sharp has a 50MB cache by default, used within libvips, to increase
the performance of transforming images
- this isn't relevant to us because we should never be optimizing the
same image as we check if the optimized image already exists
- I presume there is also some extra overhead of using the cache because
the memory doesn't seem to grow by 50MB
- the memory usage comparison in Ghost is pretty drastic - uploading 10
images in serial w/ jemalloc:
- with cache (default) = peak of 480MB, settles down to 330MB
- disabling cache = peak of 270MB, settles down to 161MB
- this commit disables the cache
- also adds stubbing for the function in tests
refs https://github.com/TryGhost/Ghost/issues/11944
- it's useful for consuming applications to know if images can be transformed outside of actually performing the transform (eg, when outputting "resized" image URLs)
- added `canTransformFiles()` that returns a boolean for whether or not `sharp` is installed

closes#10144
- When the input image is well optimized and has smaller byte size than the processed one it's still being used
- Bumped sharp version to have access to `size` property
