Function image_buffer_to_tightly_packed 

pub fn image_buffer_to_tightly_packed(
    buff: &[u8],
    width: usize,
    height: usize,
    stride: usize,
    format: ImageFormat,
) -> Result<Vec<u8>, Error>

Converts an image buffer to a tightly packed owned buffer.

Notes

• strides less than width * bytes_per_pixel are allowed
• if the buffer is too small, InvalidInput is returned
