Each function is reduced to just 3 opcodes on x86: https://godbolt.org/z/n6q6zxnh6 WebAssembly benefits as well: https://godbolt.org/z/fcETE9GYn This should improve load-time performance because read_f64_me is used frequently (for each AVM1 double constant). |

swf
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 = swf::parse_swf(reader).unwrap();
println!("The SWF has {} frames", swf.header.num_frames);
Try cargo run --example reading in this repository to run this example.
Writing
use swf::*;
let swf = Swf {
header: Header {
version: 6,
compression: Compression::Zlib,
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: 60.0,
num_frames: 1,
},
tags: vec![
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(&swf, writer).unwrap();
Try cargo run --example writing in this repository to run this example.
