where
    T: AsPrimitive<f32> + AsPrimitive<f64>,
{
    // Required methods
    fn to_f32_normalized(&self) -> Option<f32>;

}

Trait for converting the provided value to a normalized float.

This is used for image processing where a lot of operations rely on floating values.

Required Methods

fn to_f32_normalized(&self) -> Option<f32>

Convert the value to a 32 bit float.

The value will be in a normalized range according to color depths.

For example in u8, a value of 255 would be represented as 1.0.

Returns None if it overflows and could not be represented.

fn to_f64_normalized(&self) -> Option<f64>

Convert the value to a 64 bit float

The value will be in a normalized range according to color depths.

For example in u8, a value of 255 would be represented as 1.0.

Returns None if it overflows and could not be represented.

fn from_f32_normalized(value: f32) -> Option<T>

Converts the f32 value to the provided type

Returns None if it overflows and could not be represented.

fn from_f64_normalized(value: f64) -> Option<T>

Converts the f64 value to the provided type

Returns None if it overflows and could not be represented.

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.
