relrelb 5f6d8d72ea render: Skip unreasonably large bitmaps Some SWFs report unreasonable bitmap dimensions, and trying to reserve enough capacity for them always fails. To avoid panics, skip those bitmaps. Fixes #1191 Fixes #2759 Fixes #10701		2023-07-24 09:37:37 +03:00

swf

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

# Cargo.toml
[dependencies]
swf = "0.2"

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();
