(PECL imagick 2.0.0) Selects a threshold for each pixel based on a range of intensity bool Imagick::adaptiveThresholdImage ( int $width, int $height, int $offset ) Selects an individual threshold for each pixel based on the range of intensity values in its local neighborhood. This allows for thresholding of an image whose global intensity histogram doesn't contain distinctive peaks. Parameters:

(PECL imagick 2.0.0) Adaptively sharpen the image bool Imagick::adaptiveSharpenImage ( float $radius, float $sigma [, int $channel = Imagick::CHANNEL_DEFAULT ] ) Adaptively sharpen the image by sharpening more intensely near image edges and less intensely far from edges. This method is available if Imagick has been compiled against ImageMagick version 6.2.9 or newer. Parameters: radi

(PECL imagick 2.0.0) Adaptively resize image with data dependent triangulation bool Imagick::adaptiveResizeImage ( int $columns, int $rows [, bool $bestfit = false ] ) Adaptively resize image with data-dependent triangulation. Avoids blurring across sharp color changes. Most useful when used to shrink images slightly to a slightly smaller "web size"; may not look good when a full-sized image is adaptively resized to a thumb

(PECL imagick 2.0.0) Adds adaptive blur filter to image bool Imagick::adaptiveBlurImage ( float $radius, float $sigma [, int $channel = Imagick::CHANNEL_DEFAULT ] ) Adds an adaptive blur filter to image. The intensity of an adaptive blur depends is dramatically decreased at edge of the image, whereas a standard blur is uniform across the image. This method is available if Imagick has been compiled against ImageMagick versio

(PECL gmagick >= Unknown) Sets the normalized value of one of the channels public GmagickPixel GmagickPixel::setcolorvalue ( int $color, float $value ) Sets the value of the specified channel of this object to the provided value, which should be between 0 and 1. This function can be used to provide an opacity channel to a GmagickPixel object. Parameters: color One of t

(PECL gmagick >= Unknown) Sets the color public GmagickPixel GmagickPixel::setcolor ( string $color ) Sets the color described by the GmagickPixel object, with a string (e.g. "blue", "#0000ff", "rgb(0,0,255)", "cmyk(100,100,100,10)", etc.). Parameters: color The color definition to use in order to initialise the GmagickPixel object. Returns: T

(PECL gmagick >= Unknown) Gets the normalized value of the provided color channel public float GmagickPixel::getcolorvalue ( int $color ) Retrieves the value of the color channel specified, as a floating-point number between 0 and 1. Parameters: color The channel to check, specified as one of the Gmagick channel constants. Returns: The value o

(PECL gmagick >= Unknown) Returns the color count associated with this color public int GmagickPixel::getcolorcount ( void ) Returns the color count associated with this color Returns: Returns the color count as an integer on success, throws GmagickPixelException on failure.

(PECL gmagick >= Unknown) Returns the color public mixed GmagickPixel::getcolor ([ bool $as_array [, bool $normalize_array ]] ) Returns the color described by the GmagickPixel object, as an array. If the color has an opacity channel set, this is provided as a fourth value in the list. Parameters: as_array True to indicate return of array instead of string

(PECL gmagick >= Unknown) The GmagickPixel constructor public GmagickPixel::__construct ([ string $color ] ) Constructs an GmagickPixel object. If a color is specified, the object is constructed and then initialised with that color before being returned. Parameters: color The optional color string to use as the initial value of this object. Returns:
