Struct PdfDocument 

pub struct PdfDocument { /* private fields */ }

Parsed PDF document handle used for inspection, redaction, and save.

Implementations

impl PdfDocument

pub fn open(bytes: &[u8]) -> PdfResult<Self>

Opens an unencrypted PDF from raw bytes, or an encrypted PDF whose user password is empty. For encrypted PDFs that require a user- or owner-supplied password, use PdfDocument::open_with_password.

pub fn open_with_password(bytes: &[u8], password: &[u8]) -> PdfResult<Self>

Opens an encrypted PDF from raw bytes using the supplied password. The password is tried first as the user password, then as the owner password; if neither authenticates, the function returns pdf_objects::PdfError::InvalidPassword. For unencrypted documents the password is ignored.

pub fn open_with_certificate( bytes: &[u8], cert_der: &[u8], private_key_der: &[u8], ) -> PdfResult<Self>

Opens an Adobe.PubSec-encrypted PDF using the recipient’s X.509 certificate and matching RSA private key, both DER-encoded (PKCS#8 for the private key, the standard form returned by most browser key-management APIs). Returns pdf_objects::PdfError::InvalidPassword when no recipient blob in the PDF unwraps with the supplied private key. For password-encrypted or unencrypted documents this returns pdf_objects::PdfError::Unsupported — use PdfDocument::open_with_password / PdfDocument::open respectively.

pub fn page_count(&self) -> usize

Returns the number of pages in the parsed document.

pub fn page_size(&self, page_index: usize) -> PdfResult<PageSize>

Returns the normalized page size for a zero-based page index.

pub fn extract_text(&self, page_index: usize) -> PdfResult<PageText>

Extracts page text and geometry for the current supported subset.

pub fn search_text( &self, page_index: usize, query: &str, ) -> PdfResult<Vec<TextMatch>>

Searches page text in visual glyph order and returns page-space match geometry.

pub fn apply_redactions( &mut self, plan: RedactionPlan, ) -> PdfResult<ApplyReport>

Applies a redaction plan in place to the opened document.

pub fn save(&self) -> PdfResult<Vec<u8>>

Saves the current document state as a new deterministic full-save PDF.
