Imagick::gaussianBlurImage — Blurs an image
Description
This function is currently not documented; only its argument list is available.
Blurs an image. We convolve the image with a Gaussian operator of the given radius and standard deviation (sigma). For reasonable results, the radius should be larger than sigma. Use a radius of 0 and selects a suitable radius for you.
Parameters
- radius
-
The radius of the Gaussian, in pixels, not counting the center pixel.
- sigma
-
The standard deviation of the Gaussian, in pixels.
- channel
-
Provide any channel constant that is valid for your channel mode. To apply to more than one channel, combine channeltype constants using bitwise operators. Defaults to Imagick::CHANNEL_ALL. Refer to this list of channel constants.
Return Values
Returns TRUE on success.
