Expand description
A trait for algorithms which compute the Discrete Cosine Transform Type 1 (DCT1)
Required Methods
sourcefn process_dct1_with_scratch(&self, buffer: &mut [T], scratch: &mut [T])
fn process_dct1_with_scratch(&self, buffer: &mut [T], scratch: &mut [T])
Computes the DCT Type 1 on the provided buffer, in-place. Uses the provided scratch
buffer as scratch space.
Does not normalize outputs.
Provided Methods
sourcefn process_dct1(&self, buffer: &mut [T])
fn process_dct1(&self, buffer: &mut [T])
Computes the DCT Type 1 on the provided buffer, in-place.
This method may allocate a Vecprocess_dct1_with_scratch
instead.
Does not normalize outputs.
