Trait rustdct::Dct7

pub trait Dct7<T: DctNum>: RequiredScratch + Length + Sync + Send {
    pub fn process_dct7_with_scratch(&self, buffer: &mut [T], scratch: &mut [T]);

    pub fn process_dct7(&self, buffer: &mut [T]) { ... }
}

An umbrella trait for algorithms which compute the Discrete Cosine Transform Type 7 (DCT7)

Required methods

pub fn process_dct7_with_scratch(&self, buffer: &mut [T], scratch: &mut [T])

Computes the DCT Type 7 on the provided buffer, in-place. Uses the provided scratch buffer as scratch space.

Provided methods

pub fn process_dct7(&self, buffer: &mut [T])

Computes the DCT Type 7 on the provided buffer, in-place.

This method may allocate a Vec of scratch space as needed. If you'd like to reuse that allocation between multiple computations, considr calling process_dct7_with_scratch instead.
