Hi - I tried to convert a PDF file with this tool using the default options and it doesn't seem to work. This PDF file has 2 columns on some pages and 3 columns on others. I expected the pages to be 1 column, but they continued to be 2 and 3. I also tried specifying "co" and "1" on the interactive display, with the same result. I believe this PDF file is created from a hard copy document being scanned in. Could this be a problem? Or, is there some other option to specify? I've looked at the help for the options, but I can't see any that make sense. Thanks for any help.
