PDF-Overlay
__NOROBOTS__
PDF-Overlay is a utility program for merging FineReader OCR output with original high resolution PDFs.
STATUS
Current Status: pre-Alpha, FOR TESTING ONLY
Know Issues
- Page size default to US Letter
- PDF Meta-data is lost
- Underlying text position is slightly offset
Motivation
FineReader can produce output with text under the scanned image. However the resulting PDF has only a FAX quality image of the original scanned page - this is unacceptable for archiving documents. PDF-Overlay solves this problem by overlaying the original high-resolution scan on top of FineReader's output.
Download and Source Code
PDF-Overlay Usage
To operate, drag and drop the original high-resolution PDF onto PDF-Overlay.app. The FineReader output must be in the same folder as the original, and named with FineReader's default naming scheme (i.e. "xxx processed by FineReader.pdf").
PDF-Overlay ignores FineReader and its own output PDFs, so it is safe to simply select-all PDFs and drop them on PDF-Overlay. Only PDFs with matching FineReader output will be processed. PDF-Overlay always overwrites the merged PDF.
Example File Naming
Input Files:
- 2008-05-27.pdf
- 2008-05-27 processed by FineReader.pdf
Output File:
- 2008-05-27 merged by PDF-Overlay.pdf
Recommended FineReader Settings
Since PDF-Overlay over-writes (over-paints really) the FineReader PDF, it is best to setup FineReader to produce small, mainly-text documents with light-weight images. This will minimize the size of the merged PDF.
