Failure to read PDF with image

Using this to extract data from images:

      for (i, o) in images.iter().enumerate() {
            let img = match **o {
                XObject::Image(ref im) => im,
                _ => continue
            };

            let data = img.image_data(&resolver)?;

            let mut rgb_img: RgbImage = ImageBuffer::new(img.width, img.height);
            rgb_img.copy_from_slice(data.as_bytes());

Not all images are RGB images.
You have to take a look at color_space to find out what it is.
