Struct XRefStream 

pub struct XRefStream {
    pub dict: PdfDictionary,
    pub data: Vec<u8>,
    pub widths: Vec<usize>,
    pub index: Vec<(u32, u32)>,
}

Cross-reference stream parser

Fields

dict: PdfDictionary

Stream dictionary

data: Vec<u8>

Decoded stream data

widths: Vec<usize>

Field widths from W array

index: Vec<(u32, u32)>

Index array (pairs of [first_object_number, count])

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 from already-decoded entry bytes.

stream_data must be the decoded (decompressed) content: the caller is responsible for running stream.decode() before invoking this function. The stream_dict may still carry /Filter and /DecodeParms, but this function does NOT apply them. Passing raw compressed bytes here would re-inflate already-inflated data and produce a bogus “Xref stream data truncated” error (issue #341).

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
