- Fully rasterize and OCR each page.
- New Save options:
- Save as vector PDF with existing objects (including visible text)
preserved and merged with OCR.
- Save as searchable PDF where each page has a single image which
overlays hidden OCR data.
- Maintain original color if applicable, or
- Convert to grayscale before saving, or
- Convert to monochrome using a dithering algorithm, or
- Convert to monochrome using dynamic or specified thresholding.
- Specify or automatically assign resolution to control PDF size.
