One could add an option for graphics to convert regular dot pattern fills to an average unit area. (FFT Filter)
So far this is not the case because it is assumed to belong to the correct content.
You should then be able to give it as an option. You can then optionally search for these fillings in the image.
This is an interesting feature. I’ll pass it along to my team for discussion.
Thank you for forwarding, Tim He 
Yes, that would also affect many images with a pronounced print grid, which could then have a much better quality than pure graphic FFT filters.
That quality is not available on the market.
We specialize more for photographs than graphics but the functionality could potentially still help you with your work.
Yes, it would be nice if you could implement that.
