Software equivalent to PaperPort on Win
I have been searching for a software from Open Source running on Linux/Unix equivalent to PaperPort/PageMaker/OmniPage/etc. for Win. They are graphic editing software with database integrated. They have a platform/table to retain scanned documents visually and combine them as a file. The file can be saved in many formats. Each page inside the file can be rearranged, i.e. page-1 can be re-inserted as page-13, etc. and all pages will be re-numbered automatically. The pages can be editted both graphically or textwise.
They have a powerful database to search documents on their titiles or contents. The database can be update at night at a pre-fixed time. The documents can be OCR.
To my understanding a graphic editing software such as GIMP can do the job. But the operation would not be so simple and handy.
