Imagick::sketchImage — Simulates a pencil sketch
Description
bool Imagick::sketchImage
( float $radius
, float $sigma
, float $angle
)
WarningThis 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.
