Function libvips::ops::logmat

pub fn logmat(sigma: f64, min_ampl: f64) -> Result<VipsImage>

VipsLogmat (logmat), make a Laplacian of Gaussian image sigma: f64 -> Radius of Gaussian min: 0.000001, max: 10000, default: 1 min_ampl: f64 -> Minimum amplitude of Gaussian min: 0.000001, max: 10000, default: 0.1 returns VipsImage - Output image
