Trait rustdct::mdct::IMDCT [−] [src]

pub trait IMDCT<T: DCTnum>: Length {
    fn process_split(
        &mut self, 
        input: &[T], 
        output_a: &mut [T], 
        output_b: &mut [T]
    );

    fn process(&mut self, input: &[T], output: &mut [T]) { ... }
}

An umbrella trait for algorithms which compute the Inverse Modified Discrete Cosine Transform (IMDCT)

Required Methods

`fn process_split(&mut self, input: &[T], output_a: &mut [T], output_b: &mut [T])`

Computes the MDCT on the input buffer and places the result in the output buffer. Puts the first half of the output in output_a, and puts the first half of the output in output_b.

To make overlapping array segments easier, this method DOES NOT zero out the output buffer, instead it adds (via operator+) the result of the IMDCT to what's already in the buffer.

Provided Methods

`fn process(&mut self, input: &[T], output: &mut [T])`

Computes the MDCT on the input buffer and places the result in the output buffer.
