Expand description
A trait for algorithms which compute the Discrete Cosine Transform Type 7 (DCT7)
Required methods
fn process_dct7_with_scratch(&self, buffer: &mut [T], scratch: &mut [T])
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.
Does not normalize outputs.
Provided methods
fn process_dct7(&self, buffer: &mut [T])
fn process_dct7(&self, buffer: &mut [T])
Computes the DCT Type 7 on the provided buffer, in-place.
This method may allocate a Vecprocess_dct7_with_scratch
instead.
Does not normalize outputs.
