* Add OCR test data and implement tests for various document formats
- Created HTML file with multiple images for testing OCR extraction.
- Added several PDF files with different layouts and image placements to validate OCR functionality.
- Introduced PPTX files with complex layouts and images at various positions for comprehensive testing.
- Included XLSX files with multiple images and complex layouts to ensure accurate OCR extraction.
- Implemented a new test suite in `test_ocr.py` to validate OCR functionality across all document types, ensuring context preservation and accuracy.
* Enhance OCR functionality and validation in document converters
- Refactor image extraction and processing in PDF, PPTX, and XLSX converters for improved readability and consistency.
- Implement detailed validation for OCR text positioning relative to surrounding text in test cases.
- Introduce comprehensive tests for expected OCR results across various document types, ensuring no base64 images are present.
- Improve error handling and logging for better debugging during OCR extraction.
* Add support for scanned PDFs with full-page OCR fallback and implement tests
* Bump version to 0.1.6b1 in __about__.py
* Refactor OCR services to support LLM Vision, update README and tests accordingly
* Add OCR-enabled converters and ensure consistent OCR format across document types
* Refactor converters to improve import organization and enhance OCR functionality across DOCX, PDF, PPTX, and XLSX converters
* Refactor exception imports for consistency across converters and tests
* Fix OCR tests to match MockOCRService output and fix cross-platform file URI handling
* Bump version to 0.1.6b1 in __about__.py
* Skip DOCX/XLSX/PPTX OCR tests when optional dependencies are missing
* Add comprehensive OCR test suite for various document formats
- Introduced multiple test documents for PDF, DOCX, XLSX, and PPTX formats, covering scenarios with images at the start, middle, and end.
- Implemented tests for complex layouts, multi-page documents, and documents with multiple images.
- Created a new test script `test_ocr.py` to validate OCR functionality, ensuring context preservation and accurate text extraction.
- Added expected OCR results for validation against ground truth.
- Included tests for scanned documents to verify OCR fallback mechanisms.
* Remove obsolete HTML test files and refactor test cases for file URIs and OCR format consistency
- Deleted `html_image_start.html` and `html_multiple_images.html` as they are no longer needed.
- Updated `test_file_uris` in `test_module_misc.py` to simplify assertions by removing unnecessary `url2pathname` usage.
- Removed `test_ocr_format_consistency.py` as it is no longer relevant to the current testing framework.
* Refactor OCR processing in PdfConverterWithOCR and enhance unit tests for multipage PDFs
* Revert
* Revert
* Update REDMEs
* Refactor import statements for consistency and improve formatting in converter and test files
