Gmagick::reducenoiseimage — Smooths the contours of an image

說明

public Gmagick::reducenoiseimage(float $radius): Gmagick

Smooths the contours of an image while still preserving edge information. The algorithm works by replacing each pixel with its neighbor closest in value. A neighbor is defined by radius. Use a radius of 0 and Gmagick::reducenoiseimage() selects a suitable radius for you.

參數(shù)

radius

The radius of the pixel neighborhood.

返回值

The Gmagick object.
