This is a binding to the libwebp library.
Usage
Preparation
# Cargo.toml
[dependencies]
libwebp = { version = "0.1.2", features = ["0_6"] }
Simple decoding
use libwebp::WebPDecodeRGBA;
let data: &[u8];
let (width, height, buf) = WebPDecodeRGBA(data).unwrap();
eprintln!("width = {}, height = {}", width, height);
eprintln!(
"top-left pixel: rgba({}, {}, {}, {})",
buf[0],
buf[1],
buf[2],
buf[3] as f64 / 255.0,
)
Simple encoding
use libwebp::WebPEncodeRGBA;
let buf: &[u8] = &[
255, 255, 255, 255, // white
255, 0, 0, 255, // red
0, 255, 0, 255, // green
0, 0, 255, 255, // blue
];
let data = WebPEncodeRGBA(buf, 2, 2, 8, 75.0).unwrap();
let lossless_data = WebPEncodeLosslessRGBA(buf, 2, 2, 8).unwrap();

Linking
If libwebp is found in the system, it links against the library. Otherwise it builds and links against the bundled libwebp.
In these cases, static link is preferred:
- For musl target.
- When cross-compiling.
static
feature is turned on.LIBWEBP_SYS_STATIC
environment variable is set to1
when building.
