Imagick::floodFillPaintImage

(PECL imagick 2 >= 2.3.0, PECL imagick 3)

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

Description

publicImagick::floodFillPaintImage(
    mixed$fill,
    float$fuzz,
    mixed$target,
    int$x,
    int$y,
    bool$invert,
    int$channel = Imagick::CHANNEL_DEFAULT
): bool

Changes the color value of any pixel that matches target and is an immediate neighbor. This method is a replacement for deprecated Imagick::paintFloodFillImage(). This method is available if Imagick has been compiled against ImageMagick version 6.3.8 or newer.

Parameters

fill: ImagickPixel object or a string 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.
target: ImagickPixel object or a string containing the target color to paint
x: X start position of the floodfill
y: Y start position of the floodfill
invert: If true paints any pixel that does not match the target color.
channel: Provide any channel constant that is valid for your channel mode. To apply to more than one channel, combine channel constants using bitwise operators. Defaults to Imagick::CHANNEL_DEFAULT. Refer to this list of channel constants

Return Values

Returns true on success.

Examples

Example #1 Imagick::floodfillPaintImage() example

<?php


$im = new Imagick();


$im->newImage(100, 50, "red");
$im->newImage(100, 50, "green");
$im->newImage(100, 50, "blue");


$im->resetIterator();
$combined = $im->appendImages(true);


$combined->writeImage("floodfillpaint_intermediate.png");


$x = 1;
$y = 1;


$target = $combined->getImagePixelColor($x, $y);


$combined->floodfillPaintImage("black", 1, $target, $x, $y, false);


$combined->writeImage("floodfillpaint_result.png");
?>

The above example will output something similar to:
