Function image_dimensions

pub fn image_dimensions<P>(path: P) -> ImageResult<(u32, u32)>
where
    P: AsRef<Path>,

Read a tuple containing the (width, height) of the image located at the specified path. This is faster than fully loading the image and then getting its dimensions.

Try ImageReader for more advanced uses, including guessing the format based on the file’s content before its path or manually supplying the format.
