PDF Library (Pdf)

PDF Data Library ("pdf" feature)

Functions for working with PDF files, loaded into Stof via the custom Data type. Requires the "pdf" feature flag to be enabled.

Pdf.extract_images(pdf: Data<Pdf>) -> list

Given a data pointer to a PDF document, extract all images from every page, returning them as a list of maps with image data.

// import './test_stof_pdf.pdf'; // taken from stof PDF format tests
const images = self.pdf.extract_images();
assert_eq(images.len(), 1);
assert_eq(images[0].get('height'), 500);
assert_eq(images[0].get('width'), 1250);

Pdf.extract_text(pdf: Data<Pdf>) -> str

Given a data pointer to a PDF document, extract all text from the PDF file and return it as a string.

// import './test_stof_pdf.pdf'; // taken from stof PDF format tests
const text = self.pdf.extract_text();
assert_eq(text, "Example Stof\nDocument\n");
