Imagick::sketchImage — Simulates a pencil sketch

Description

bool Imagick::sketchImage ( float $radius , float $sigma , float $angle )

Warning

This function is currently not documented; only its argument list is available.

Simulates a pencil sketch. We convolve the image with a Gaussian operator of the given radius and standard deviation (sigma). For reasonable results, radius should be larger than sigma. Use a radius of 0 and Imagick::sketchImage() selects a suitable radius for you. Angle gives the angle of the blurring motion.

Parameters

radius
sigma
angle

Return Values

Returns TRUE on success.
