Description
bool Imagick::gaussianBlurImage
( float $radius
, float $sigma
[, int $channel
] )
WarningThis 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.
Errors/Exceptions
Throws ImagickException on error.
