pub fn save_rgba(
path: impl AsRef<Path>,
w: u32,
h: u32,
rgba: &[u8],
) -> Result<()>Expand description
Save an RGBA8 buffer (top row first) to path.
The format comes from the extension: .png, .jpg/.jpeg, .bmp,
.tga or .gif. An unknown or missing extension writes a BMP, which is
what the engine always wrote before it could do anything else. Formats
without an alpha channel (JPEG, BMP) get the colour only.
