I need a utility to batch convert TIFF files to indexable PDF's. The software needs to run on linux and must work from the command line. The software does not need to be open source. I've tried the conversion using tesseract and hocr2pdf however they produce PDF's with garbled text (Note: the text is only garbled if you "select all" text in the PDF). I've found other utilities but they only run under Windows or don't work from the command line. Thanks in advance.
After trying several tools (including Abbyy) I decided on: Vividata. They have decent pricing, run under Linux, and don't have a page per year limit.
