Crate libvisio_rs 

libvisio-rs — A Rust library for parsing Microsoft Visio files and converting to SVG.

Supports both .vsdx (ZIP+XML, Open Packaging) and .vsd (OLE2 binary) formats. Produces high-quality SVG output with themes, gradients, shadows, rich text, embedded images, connectors, and more.

Examples

use libvisio_rs::{convert, get_page_info, extract_text};

// Convert all pages to SVG
let svg_files = convert("diagram.vsdx", Some("/tmp/output"), None).unwrap();

// Get page info
let pages = get_page_info("diagram.vsdx").unwrap();

// Extract text
let text = extract_text("diagram.vsdx").unwrap();
