Imagick::colorFloodfillImage — Changes the color value of any pixel that matches target

警告

此函数在 Imagick 3.4.4 中被废弃，强烈建议不要应用此函数。

public Imagick::colorFloodfillImage(
    mixed $fill,
    float $fuzz,
    mixed $bordercolor,
    int $x,
    int $y
): bool

Changes the color value of any pixel that matches target and is an immediate neighbor.

fill: ImagickPixel object containing the fill color
fuzz: The amount of fuzz. For example, set fuzz to 10 and the color red at intensities of 100 and 102 respectively are now interpreted as the same color for the purposes of the floodfill.
bordercolor: ImagickPixel object containing the border color
x: X start position of the floodfill
y: Y start position of the floodfill

成功时返回 true。

错误时抛出 ImagickException。

版本	说明
PECL imagick 2.1.0	Now allows a string representing the color as first and third parameter. Previous versions allow only an ImagickPixel object.
