Use pdfplumber to extract text with layout preserved and to detect tables via page.extract_tables(). For simple text extraction, pypdf's page.extract_text() or the pdftotext command-line tool also work.
Use pypdf's PdfWriter to add pages from multiple readers and write a merged file, or write each page to its own file to split. The qpdf command-line tool also supports merging and page-range splitting.
First run check_fillable_fields.py to detect form fields. Fillable PDFs are filled with fill_fillable_fields.py using extracted field IDs; non-fillable PDFs are filled by adding text annotations at coordinates via fill_pdf_form_with_annotations.py.
Scanned PDFs contain images, not text layers, so standard parsers fail. Convert pages to images with pdf2image, then run pytesseract OCR on each image to produce searchable text.
ReportLab's built-in fonts lack Unicode subscript and superscript glyphs, so they render as solid boxes. Use the <sub> and <super> XML tags inside Paragraph objects instead of Unicode characters.
