We hit a pathological case in House (https://github.com/ruffle-rs/ruffle/issues/15154), where eagerly decoding bitmaps during preloading results in over 10GB of ram being used. With this PR, we store the compressed bitmap, and only decode it each time we instantiate it. In order to support bitmap fills, we store the decoded width/height and a lazily-initialized GPU handle in `Character::Bitmap` |

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();
