Scale down to fit an image in FOP
I found this page here explaining how scaling works with XSL-FO. Essentially, this is the snippet that I used to make it work: <fo:external-graphic src=”https://stackoverflow.com/questions/6220316/url(“https://stackoverflow.com/questions/6220316/…”)” width=”100%” content-height=”100%” content-width=”scale-to-fit” scaling=”uniform” xsl:use-attribute-sets=”img”/> I found that width=”100%” was the missing piece in your own attempts. Hope this helps future visitors.
