Implementations

impl ImageFormat

pub fn derive_from_path(path: &str) -> Option<Self>

Derive the image format from a path. It uses the file extension to pick from the supported formats, or returns None if the extension doesn’t map to a known format.

Example

assert_eq!(Some(ImageFormat::Png), ImageFormat::derive_from_path("FOO.PNG"));
assert_eq!(Some(ImageFormat::Bmp), ImageFormat::derive_from_path("Bar.Bmp"));
assert_eq!(Some(ImageFormat::Jpeg), ImageFormat::derive_from_path("baz.jpg"));
assert_eq!(None, ImageFormat::derive_from_path("Bad.txt"));
