* Use `TryFlags` instead of hard-coded binary literals.
* Rename `try_length`, `catch_length`, `finally_length` to `try_size`,
`catch_size`, `finally_size` to match SWF19 namings.
* Refactor write and fix a few bugs there:
* The actions length should not include the try, catch, finally
bodies, only the metadata of `flags`, `try_size`, `catch_size`,
`finally_size` and catch variable (either as `u8` or `SwfStr`).
* A placeholder byte should be written in place of the catch variable
when there is no catch clause.

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_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();
