pdf_form_fillFill PDF form
Fill an AcroForm PDF and write a NEW file (the source is never modified and an existing output is never overwritten). values maps exact field names to values: strings for text fields; an on-state such as "/1" or "/Yes" (or true) to check a box, "" or false to clear it. strict=true refuses the whole fill if any name is unknown. finalize=true removes the XFA packet and NeedAppearances flag so viewers render the values from their own appearance streams (fields stay editable; this is not flattening). Returns the output SHA-256 and a read-back of every text value.
pdf_form_inspectInspect PDF form fieldsread-only
List every fillable field in a PDF: exact name, type (text, button, choice, signature), current value, required flag, and for checkboxes/radios the on-state values that check them. Use the names exactly as returned when filling.
pdf_form_verifyVerify filled values are visibleread-only
Render one page, OCR it, and compare with the PDF text layer. Each value gets a verdict: VISIBLE, INVISIBLE (in the file but not on the page), RENDER-ONLY, or MISSING. region is "page" or "x0,y0,x1,y1" as page fractions; with a region and auto=true every word the text layer places in that region must also be legible. A tool failure (missing poppler or tesseract, render error) returns REFUSE with the reason and makes no finding about the document. Proves legibility only, not correctness.
pdf_sha256SHA-256 of a fileread-only
Return the SHA-256 digest of a file so the exact output can be recorded.
