Q
There are two transparent polygons drawn next to each other. When we open this file at PDF Reader we can see thick line between these triangles. When we change PDF Reader zoom the thickness of this line is changing too. I think this artifact is a result of overlapping of two adjacent transparent polygons. How to remove this line? Is there are any way to change a PDF quality? I don’t find anything about this in PDC Documentation.
Waiting for your answers.
Best regards,
Egor.
