Struct Resolver 

pub struct Resolver<'a> { /* private fields */ }

Resolves indirect object references, caching parsed objects.

Implementations

impl<'a> Resolver<'a>

pub fn with_encryption( data: &'a [u8], xref: XrefTable, encryption: Option<EncryptionState>, ) -> Self

Create a resolver with optional encryption state.

pub fn preload_object_streams(&self)

Pre-decompress and parse all object streams (ObjStm) in the PDF. This populates the object cache for all objects stored in ObjStms, avoiding per-object decompression during page rendering.

pub fn resolve(&self, obj_num: u32, _gen_num: u16) -> Result<PdfObj, PdfError>

Resolve an indirect reference to its parsed object.

pub fn deref(&self, obj: &PdfObj) -> Result<PdfObj, PdfError>

If obj is a Ref, resolve it. Otherwise return as-is.

pub fn stream_data( &self, obj_num: u32, gen_num: u16, ) -> Result<Vec<u8>, PdfError>

Resolve an object and return its decompressed stream data.

pub fn raw_stream_and_filters( &self, obj: &PdfObj, ) -> Result<(Vec<u8>, Vec<Filter>), PdfError>

Get the raw (pre-filter) stream bytes and filter list for an object. Used for peeking at JPX metadata before full decode.

pub fn stream_data_from_obj(&self, obj: &PdfObj) -> Result<Vec<u8>, PdfError>

Resolve an object and return decompressed stream data, accepting a PdfObj directly.

pub fn raw_stream_bytes(&self, obj: &PdfObj) -> Option<&[u8]>

Return the raw (undecoded, possibly encrypted) stream bytes for an object reference. Used to parse format-specific headers (e.g. JPEG SOF) before full filter decoding.

pub fn trailer(&self) -> &PdfDict

Access the trailer dictionary.

pub fn data(&self) -> &'a [u8]

Access the raw file data.

pub fn xref_len(&self) -> usize

Number of entries in the xref table.
