Simple benchmark that compares 4k water image with corrupted one.

hyperfine -i 'odiff water-4k.png water-4k-2.png water-diff.png'  'pixelmatch water-4k.png water-4k-2.png water-diff.png' 'compare water-4k.png water-4k-2.png -compose src water-diff.png'

Generate markdown results

This generates markdown output that is displayed in README.

hyperfine -i --export-markdown <PATH_TO_MARKDOWN> 'pixelmatch www.cypress.io-1.png www.cypress.io.png www.cypress-diff.png' 'compare www.cypress.io-1.png www.cypress.io.png -compose src diff-magick.png' 'ODiffBin www.cypress.io-1.png www.cypress.io.png www.cypress-diff.png'
