Is there a way to export a PDF from ArcGIS Pro 2.7.2 to PDF, ensuring there truly is no background? When I export from ArcGIS Pro to PDF, even when I specify that the map frame be transparent and the layout be transparent, when I export the map to PDF it still maintains a white background layer.
To see this in action, I went to Adobe Illustrator. I opened up 1 map PDF where I did include a white background, and then opened another map PDF where I specified a transparent/no background. I made a teal rectangle in Illustrator and dragged it to the bottom of each map to see what was covering it, pictures below.
I couldn't find much online, only this link: https://community.esri.com/t5/cartography-and-maps-questions/how-to-make-a-layout-background-transparent-in-arcgis-pro/td-p/774159
1st pic, in Pro I specific this map have a white background. It has 2 white backgrounds layers in AI, highlighted. 2nd pic, in Pro I specified the map frame have no background. It has 1 white background layer in AI, highlighted.
