I am not aware of any open source OCR software that is doing multi- column document recognition. It's more of a segmentation task, rather than recognition itself, so it should be rather implemented in a front- end, such as OCRopus. If you have a linear text flow, sandwich PDFs can be read by a screen reader smart enough in a reasonable way.
Apart from already mentioned Finereader, old Cuneiform Windows freeware seems to be able to do multi-column. -- Font size not correct in merged sandvich PDF https://bugs.launchpad.net/bugs/623438 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
