View a PDF with two columns by displaying it one column by one column Is there a way to view a PDF with two columns by displaying it column by column? I can certainly use any viewer to look at such a document but leafing around from column-to-column is very cumbersome. Even more so for scanned-in bitmaps.

The layout of many Android devices would be ideal to read a single column at a time.
If the PDF are scanned images (pure image), I don't think it's possible.

But if it's purely text (like a Word document saved as a PDF file), you can use ezPDF Reader (or its free version). When you open the PDF, click the More Options button at the lower right, and select Text Reflow. This time, you will only see 1 column.

I'm not sure what happens if there's a combination of text and picture.
