Imagick::sketchImage

Simulates a pencil sketch

&reftitle.description; public `bool` `Imagick::sketchImage` `float` `radius` `float` `sigma` `float` `angle`

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. &imagick.method.available.0x629;

&reftitle.parameters;

`radius`

- The radius of the Gaussian, in pixels, not counting the center pixel

`sigma`

- The standard deviation of the Gaussian, in pixels.

`angle`

- Apply the effect along this angle.
