Implementations

impl XRefStream

pub fn parse<R: Read + Seek>( _reader: &mut R, stream_dict: PdfDictionary, stream_data: Vec<u8>, _options: &ParseOptions, ) -> ParseResult<Self>

Parse a cross-reference stream

pub fn to_xref_entries(&self) -> ParseResult<Vec<(u32, XRefEntry)>>

Convert the cross-reference stream to XRefTable entries

pub fn trailer_dict(&self) -> &PdfDictionary

Get the trailer dictionary from the xref stream

pub fn is_hybrid(&self) -> bool

Check if this is a hybrid reference file

pub fn get_xref_stm_offset(&self) -> Option<u64>

Get the offset to additional xref stream (for hybrid files)

pub fn get_prev_offset(&self) -> Option<u64>

Get the previous xref offset
