pub fn encode_png_rgba(
    width: u32,
    height: u32,
    rgba: &[u8],
) -> Result<Vec<u8>, String>

Errors

Returns an error when rgba.len() is not exactly width * height * 4 or when the image encoder rejects the output.

Examples

use ailloli_ui_render_wgpu::capture::encode_png_rgba;

assert_eq!(&png[..8], b"\x89PNG\r\n\x1a\n");
