I used a PDF export feature in LogiReports to create a PDF. This shouldn't much matter, because I have Adobe Acrobat Pro and should be able to edit what it exported. It's created a report with a gridlike design of boxes (it's not perfect grid; see picture). The thing is, I cannot figure out how to alter or get rid of this grid in Adobe Acrobat Pro. When I use any PDF-to-HTML converter, this grid gets turned into a full-page PNG.
How can I find this image in Acrobat and remove it?
