I often import pdfs whose origin is almost always someone’s presentation, distilled out of powerpoint or keynote or open office suite. I cannot tell what correlates with this, but sometimes when I import them, they appear in rotated by 90 degrees like portrait, and sometimes landscape. Always, in preview or safari, they look appropriately landscape. So, two questions:
a. what causes this abrupt change?
b. how can I rotate each page within EF so I can read them?
