//! This example shows how you can track PDF limits of your chunks.

use pdf_writer::{Chunk, Content, Limits, Name, Ref};

fn main() {
    let mut limits = Limits::new();

    let mut content = Content::new();
    content.transform([-3.4, 0.0, 0.0, 3.1, 100.0, 100.0]);
    content.line_to(15.0, -26.1);
    let buf = content.finish();

    // This will have the limits:
    // - Max real number: 26.1 (for negative values we use their absolute value)
    // - Max int number 100 (even though above 100.0 is a float number, it will be coerced into an
    //   integer, and thus counts towards the int limit)
    limits.merge(buf.limits());

    let mut chunk = Chunk::new();
    chunk.stream(Ref::new(1), &buf.into_vec());
    chunk.type3_font(Ref::new(2)).name(Name(b"A_long_font_name"));

    // This will update the limit for the maximum name and dictionary length.
    limits.merge(chunk.limits());

    // The combined limits of the content and the chunk.
    assert_eq!(limits.int(), 100);
    assert_eq!(limits.real(), 26.1);
    assert_eq!(limits.name_len(), 16);
    assert_eq!(limits.dict_entries(), 3);
