Function decode 

pub fn decode(
    bytes: &[u8],
) -> Result<(DynamicImage, Option<ImageFormat>), ImageError>

Decodes an image, with its pixels upright by its EXIF orientation.

The API ignores the orientation, so the pixels must be upright.

Errors

Returns the ImageError of the decoder. Returns ImageError::Limits if the pixels need more than 512 MiB of memory, before the decode allocates them.
