pub fn parse_xref_table(
source: &[u8],
offset: u64,
) -> Result<(XrefSection, u64), PdfError>Expand description
Parse a traditional cross-reference table starting at offset.
The table begins with the xref keyword followed by one or more subsections.
Each subsection has a header start_id count and then count entries of
exactly 20 bytes each (nnnnnnnnnn ggggg n \r\n or nnnnnnnnnn ggggg f \r\n).
Returns the parsed XrefSection and the byte offset after the table
(positioned just before the trailer keyword).
