1//! This example shows how you can iterate over the content stream of all pages in a PDF.

7fn main() {

10        PathBuf::from(env!("CARGO_MANIFEST_DIR")).join("../hayro-tests/pdfs/text_with_rise.pdf"),
11    )
12    .unwrap();

14    // Then create a new PDF file from it.
15    //
16    // Here we are just unwrapping in case reading the file failed, but you
17    // might instead want to apply proper error handling.
18    let pdf = Pdf::new(Arc::new(data)).unwrap();

20    // First access all pages, and then iterate over the operators of each page's
21    // content stream and print them.
