pub fn encode(elevations: &[f32], width: u32, height: u32) -> Vec<u8> ⓘExpand description
Encode elevations (metres) into a flat width × height × 3 RGB buffer.
Walks elevations in row-major order and delegates to
encode_pixel for each sample.
§Panics
Panics if elevations.len() != (width * height) as usize.
