Struct PdfWriter 

pub struct PdfWriter {
    pub objects: Vec<(u32, PdfObject)>,
    pub version: (u8, u8),
    /* private fields */
}

Low-level PDF writer that accumulates indirect objects and serializes them into a valid PDF byte stream.

Fields

objects: Vec<(u32, PdfObject)>

Stored indirect objects: (object number, object).

version: (u8, u8)

PDF version as (major, minor), e.g. (1, 7).

Implementations

impl PdfWriter

pub fn new() -> Self

Create a new writer with default PDF 1.7 version.

pub fn alloc_object_num(&mut self) -> u32

Allocate the next object number without adding an object. Useful for forward references.

pub fn add_object(&mut self, obj: PdfObject) -> IndirectRef

Add an object, assigning it the next available object number. Returns an IndirectRef that can be used to reference this object.

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

Set (or replace) an object at a specific object number. If an object with this number already exists, it is replaced.

pub fn write_to_bytes(&self, catalog_ref: &IndirectRef) -> Result<Vec<u8>>

Serialize all objects into a complete PDF byte stream.

pub fn write_to_file( &self, path: &Path, catalog_ref: &IndirectRef, ) -> Result<()>

Serialize and write to a file.

Trait Implementations

impl Default for PdfWriter

fn default() -> Self

Returns the “default value” for a type.
