Trait for “intensity” images (grayscale, grayscale+alpha, RGB, RGBA).

Hence it s a trait for grayscale (1-channel), grayscale+alpha (2-channel), RGB (3-channel), and RGBA images (4-channel).

This trait provides methods for converting between different image type. As of now, three scalar type are supported: u8, u16, and f32:

• u8 images are in the range [0, 255], i.e. 100% intensity corresponds to 255.

• u16 images are in the range [0, 65535], i.e. 100% intensity corresponds to 65535.

• f32 images shall be in the range [0.0, 1.0] and 100% intensity corresponds to 1.0. If the f32 is outside this range, conversion results may be surprising.

These are image type which typically used for computer vision and graphics applications.

Required Methods

fn to_grayscale(img: Self) -> GenMutImage<2, 0, Scalar, Scalar, 1, 1>

Converts the image to a grayscale image.

fn to_grayscale_alpha( img: Self, ) -> GenMutImage<3, 1, Scalar, Matrix<Scalar, Const<2>, Const<1>, ArrayStorage<Scalar, 2, 1>>, 2, 1>

Converts the image to a grayscale_alpha image.

fn to_rgb( img: Self, ) -> GenMutImage<3, 1, Scalar, Matrix<Scalar, Const<3>, Const<1>, ArrayStorage<Scalar, 3, 1>>, 3, 1>

Converts the image to a RGB image.

fn to_rgba( img: Self, ) -> GenMutImage<3, 1, Scalar, Matrix<Scalar, Const<4>, Const<1>, ArrayStorage<Scalar, 4, 1>>, 4, 1>

Converts the image to a RGBA image.

fn convert_to<OtherScalar>(img: Self) -> Self::CastedMutImage<OtherScalar>

where OtherScalar: IsIntensityScalar,

Converts the image to a u8 image.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
