Lossy JBIG2 has been removed due to well-documented risks of character
substitution errors (e.g., 6/8 confusion). The --jbig2-lossy and
--jbig2-page-group-size arguments are now deprecated and ignored with
a warning.
Changes:
- Remove jbig2_lossy and jbig2_page_group_size from OCROptions
- Simplify optimize.py to use single-image JBIG2 encoding only
(no symbol dictionaries/JBIG2Globals)
- Remove convert_group() from jbig2enc.py
- Deprecate CLI args with warnings for backward compatibility
- Update documentation to explain lossless-only JBIG2
This commit introduces Pydantic models for plugin-specific options in OCRmyPDF, focusing on:
- Creating TesseractOptions, OptimizeOptions, and GhostscriptOptions
- Adding backward compatibility properties
- Maintaining existing CLI and API functionality
- Preparing for future plugin option registration system
The changes include:
- Added type-annotated option models with validation
- Updated OCROptions to include legacy fields
- Added backward compatibility properties for jbig2 options
- Prepared groundwork for dynamic plugin option handling
