Compare with:

download(&block)

Downloads the file associated with this preview’s variant. If no block is given, the entire file is read into memory and returned. That’ll use a lot of RAM for very large files. If a block is given, then the download is streamed and yielded in chunks. Raises ActiveStorage::Preview::UnprocessedError if the preview has not been processed yet.

Parameters

block block
