Under macOS I want to convert HTML files with referenced images on the command line/programatically to webarchives.
Given a sample file
<html><body> <h1>File with resource</h1> <p>This file shows text and references an image.</p> <img src="sample.jpg" /> </body></html>
and an image
sample.jpg in the same directory, I can view the html file in any browser and it is render with the image. To convert to a webarchive I tried:
textutil -convert webarchive sample.html
but the resulting
sample.webarchive does not, when opened in Safari, render the image - though it contains it (see comments).
How can I do the conversion from the command line correctly, so that the result contains and renders the image? After all that's what webarchives are for!
