Detect white text on white background

[HeningWinterNN]

Hi forum

I do not know how to achieve this so I am reaching out to you...

I want to detect if a PDF has white text (that is can do) on white background (that's the hard part!).

So far the action list is this:
Select All
Select Text Segments
Select fill color (CMYK 0,0,0,0)
Log selection

... this must be something with AND'ing the background if this is white, but it do not seem possible to select background color...

Best regards,

It sounds like you're looking for the "Select overlapping objects" action.
