see page 145:

  • SumatraPDF v 3.1.2 64-bit on win7 show an image as a black rectangle, flowed by text;
  • Firefox built-in pdf viewer show some pixel painting, flowed by text.

Agreed all recent versions of SumatraPDF see an object redacting the image and part covering the text.
Agreed that object is not rendered by OLDER 1.02 or NEWER 1.14 MuPDF
However is rendered incorrectly by MuPDF 1.1 to 1.13 thus a MuPDF library bug impacting SumatraPDF
