Functions

func InspectImage

func InspectImage(system fs.FS, link manifest.Link, algorithms []manifest.HashAlgorithm) (*manifest.Link, error)

InspectImage inspects an image located in the provided filesystem, using the provided link's manifest.HREF as a path. Additional properties from the link, such as the mediatype.MediaType, may be used, and should be included. A copy of the provided link will be returned, with the `size`, `width`, `height` and `properties.animated` attributes set. A slice of manifest.HashAlgorithm can be provided, in which case the returned link will also have `properties.hash` set with the computed hashes. Currently, the supported algorithms are: manifest.HashAlgorithmSHA256, manifest.HashAlgorithmMD5, manifest.HashAlgorithmPhashDCT, and `https://blurha.sh` (BlurHash). The latter two are visual hashes, which are more computationally expensive.

func MatchImage

func MatchImage(link manifest.Link, hashes manifest.HashList) (bool, error)

MatchImage compares the link with the given hashes to determine if they match.
