pub struct FreqScaler;

Implementations

impl FreqScaler

pub fn create(
    freq_scale: FrequencyScale,
    f_max_orig: usize,
    f_max_new: usize
) -> Box<dyn FreqScalerTrait>

Create an instance of [FreqScalerTrait] given the FrequencyScale.

Arguments

• freq_scale - The FrequencyScale to implement.
• f_max_orig - the half the data length, i.e. the nyquist frequency.
• f_max_new - The output grid/image height in cells/pixels.
