relrelb e9167cf43c swf: Add minimal offset table enforcement in `DefineFont2/3`
Previously, the offset table and code table offset were completely
ignored. But as it seems, Flash does look into these offsets in
order to avoid exceedingly reading glyph shapes. For now, avoid
exceedingly reading empty and 1-byte glyph shapes, and add debug
assertions that verify the correctness of the offset table and code
table offset, to help diagnosing related bugs in the future.

swf

crates.io docs.rs

A Rust library for reading and writing the Adobe Flash SWF file format.

# Cargo.toml
[dependencies]
swf = "0.1"

Reading

use std::io::BufReader;
use std::fs::File;

let file = File::open("file.swf").unwrap();
let reader = BufReader::new(file);
let swf_buf = swf::decompress_swf(reader).unwrap();
let swf = swf::parse_swf(&swf_buf).unwrap();
println!("The SWF has {} frame(s).", swf.header.num_frames());
println!("The SWF has {} tag(s).", swf.tags.len());

Try cargo run --example reading in this repository to run this example.

Writing

use swf::*;
let header = Header {
    compression: Compression::Zlib,
    version: 6,
    stage_size: Rectangle {
        x_min: Twips::from_pixels(0.0), x_max: Twips::from_pixels(400.0),
        y_min: Twips::from_pixels(0.0), y_max: Twips::from_pixels(400.0)
    },
    frame_rate: Fixed8::from_f32(60.0),
    num_frames: 1,
};
let tags = [
    Tag::SetBackgroundColor(Color { r: 255, g: 0, b: 0, a: 255 }),
    Tag::ShowFrame
];
let file = std::fs::File::create("file.swf").unwrap();
let writer = std::io::BufWriter::new(file);
swf::write_swf(&header, &tags, writer).unwrap();
