We'd like to extract the following information from every bitmap image present in an EPUB package:

  • height
  • width
  • size of the file
  • presence of animated content
  • cryptographic hash
  • perceptual hash

This will be based on https://pkg.go.dev/golang.org/x/image plus additional packages for hashing.

All of these info will be added to the shared model for the Link Object and also included in the JSON/RWPM output:

  • Link Objects can already document a height and a width
  • We might consider adding the size of a file as a core property of the Link Object (size?)
  • While the presence of animated content and crypto/perspectual hashes should rely on properties and extensions
