doc_converter = DocumentConverter(
format_options={
InputFormat.PDF: PdfFormatOption(pipeline_options=pipeline_options)
}
)
start_time = time.time()
conv_result = doc_converter.convert(input_doc_path)
end_time = time.time() - start_time

_log.info(f"Document converted in {end_time:.2f} seconds.")

## Export results
output_dir = Path("scratch")
output_dir.mkdir(parents=True, exist_ok=True)
doc_filename = conv_result.input.file.stem
# Export Text format:
with (output_dir / f"{doc_filename}.txt").open("w", encoding="utf-8") as fp:
fp.write(conv_result.document.export_to_text())
