pub fn semantic_diff(
a: &[u8],
b: &[u8],
planes: Option<&[String]>,
) -> Result<SemanticDiff, DocError>Expand description
Compare two documents semantically.
planes filters which planes are evaluated (None = all). Unknown plane
names are ignored. Parse failures of either input are hard errors — a
document that cannot be opened cannot be compared; use djvu validate for
damaged files.
