How to detect transparency in figures

Q Lulu complains that it cannot rip my PDF — some elements contain transparency. How do I tell which they are?

Add the following incantation:

\pdfminorversion=3 % Set PDF to 1.3 for Lulu

Figures with transparency will show up with a bright green background. (Or whatever the transparency colour is defined to be?)
