Struct CosDoc 

pub struct CosDoc { /* private fields */ }

A low-level PDF document providing access to the COS object graph.

Implementations

impl CosDoc

pub fn open(data: Vec<u8>) -> Result<Self>

Open a PDF document from raw bytes.

pub fn open_file(path: &str) -> Result<Self>

Open a PDF document from a file path.

pub fn new() -> Self

Create a new empty PDF document.

pub fn trailer(&self) -> &IndexMap<Vec<u8>, PdfObject>

Get the trailer dictionary.

pub fn trailer_mut(&mut self) -> &mut IndexMap<Vec<u8>, PdfObject>

Get a mutable reference to the trailer dictionary.

pub fn get_object(&mut self, obj_num: u32) -> Result<Option<&PdfObject>>

Get an object by its object number.

Returns the object directly (resolves the xref entry to load from file).

pub fn resolve(&mut self, obj: &PdfObject) -> Result<PdfObject>

Resolve a PdfObject::Reference to the referenced object. Returns the object itself if it’s not a reference.

pub fn create_indirect(&mut self, obj: PdfObject) -> ObjectId

Create a new indirect object and return its ObjectId.

pub fn update_object(&mut self, obj_num: u32, obj: PdfObject)

Update an existing indirect object.

pub fn xref_size(&self) -> u32

Get the number of entries in the xref table.

pub fn is_modified(&self) -> bool

Check if the document has been modified.

pub fn save_to_bytes(&mut self) -> Result<Vec<u8>>

Save the document to bytes (full save, not incremental).

All objects are written as a flat traditional xref table, even if the original used xref streams or object streams.

pub fn save_to_file(&mut self, path: &str) -> Result<()>

Save the document to a file.

pub fn decode_stream(&self, stream: &PdfStream) -> Result<Vec<u8>>

Decode a stream object’s data using its filters.
