 ## Optional Features
 
 zxing-cpp provides features that are behind [Cargo features](https://doc.rust-lang.org/cargo/reference/manifest.html#the-features-section).
 They are:
 
 * `bundled` uses a bundled version of the [zxing-cpp](https://github.com/zxing-cpp/zxing-cpp) c++ library.
-* [`image`](https://crates.io/crates/image) allows convenient/implicit `ImageView` construction from `GreyImage` and `DynamicImage`.
+* [`image`](https://crates.io/crates/image) allows convenient/implicit conversion between `ImageView`/`Image` and`GreyImage`/`DynamicImage`.
