pdftoppm does not show embedded JPEGs
This PDF was generated with LaTeX. It contains a single page with an embedded JPEG image. The LaTeX source and the original .jpg are also attached.
When I run pdftoppm test.pdf > test.ppm
(version 21.11.0), the output is a blank file.
However, Mac OS Preview and Adobe Reader both display the file correctly.
I see this problem with JPEGs from a variety of sources.
Platform: Mac OS 10.14 pdftex is from TexLive 2021
