# svpng
Rust version of [miloyip/svpng](https://github.com/miloyip/svpng).
## Usage
Either using the `svpng` crate or just copy the `src/lib.rs` somewhere you want.
## Examples
```rust
use svpng::svpng;
use std::io;
fn main() -> io::Result<()> {
{
// RGB
let mut pix = Vec::new();
for y in 0..=255 {
for x in 0..=255 {
pix.push(x);
pix.push(y);
pix.push(128);
}
}
svpng("rgb.png", 256, 256, &pix, false)?;
}
{
// RGBA
let mut pix = Vec::new();
for y in 0..=255 {
for x in 0..=255 {
pix.push(x);
pix.push(y);
pix.push(128);
pix.push(x / 2 + y / 2);
}
}
svpng("rgba.png", 256, 256, &pix, true)?;
}
Ok(())
}
