In adobe illustrator CC 2019 When I collect my illustration for export as a PDF there is a lot of blank space collected with my design. My design contains vector elements and png content. When I view in outline mode it is clear that illustrator thinks that my content is larger than it is, but in preview mode the selection box indicates that I am only selecting my desired content.
What is outline mode showing me? Why does it appear to conflict with preview mode? How can I select only my desired content? A screenshot of the outline view is below, along with an annotated version. Thanks!
