  • Prepare B&W scans for clean looking, searchable PDF

    Scan pages in, clean them up in an image editor, save to individual files. Use this command to convert each page to PDF. Combine in Acrobat Professional, and use the built-in OCR with the "Searchable Image (Exact)" option. Gives excellent image quality and file size (avoids awful JPEG image recompression that Acrobat and other OCR systems tend to do.)

  • Convert PDFLaTeX PDF to Illustrator-usable EPS

    Use this to turn a page with snippets of equations into vector paths that Adobe Illustrator can handle without choking on font embedding and substitution issues. Good for keeping fonts consistent when labeling charts and diagrams. Also good for embedding formulas into diagrams.
