Struct StructureConverter

Source

pub struct StructureConverter { /* private fields */ }

Expand description

Converter from PDF structure elements to unified content elements.

This converter handles:

Recursive structure element hierarchy conversion
MCID (Marked Content ID) to content mapping
Accessibility attribute extraction (alt text, language)
Standard structure type mapping

Implementations§

Source §

impl StructureConverter

Source

pub fn new(mcid_map: HashMap<u32, Vec<ContentElement>>) -> Self

Create a new converter with an MCID to content mapping.

§Arguments

mcid_map - HashMap of MCID values to their extracted content elements

Source

pub fn convert_struct_elem(&self, elem: &StructElem) -> Result<StructureElement>

Convert a StructElem to a StructureElement.

This recursively converts the entire hierarchy, populating children with actual content elements where MCIDs are referenced.

§Arguments

elem - The structure element to convert

§Returns

A StructureElement with populated children
