Expand description
A trait for algorithms which compute the Discrete Cosine Transform Type 8 (DCT8)
Required Methods
sourcefn process_dct8_with_scratch(&self, buffer: &mut [T], scratch: &mut [T])
fn process_dct8_with_scratch(&self, buffer: &mut [T], scratch: &mut [T])
Computes the DCT Type 8 on the provided buffer, in-place. Uses the provided scratch
buffer as scratch space.
Does not normalize outputs.
Provided Methods
sourcefn process_dct8(&self, buffer: &mut [T])
fn process_dct8(&self, buffer: &mut [T])
Computes the DCT Type 8 on the provided buffer, in-place.
This method may allocate a Vecprocess_dct8_with_scratch
instead.
Does not normalize outputs.
