(No version information available, might only be in Git)

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

Description

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

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

/* Create new imagick object */
$im = new Imagick();

/* create red, green and blue images */
$im->newImage(100, 50, "red");
$im->newImage(100, 50, "green");
$im->newImage(100, 50, "blue");

/* Append the images into one */
$im->resetIterator();
$combined = $im->appendImages(true);

/* Save the intermediate image for comparison */
$combined->writeImage("floodfillpaint_intermediate.png");

/* The target pixel to paint */
$x = 1;
$y = 1;

/* Get the color we are painting */
$target = $combined->getImagePixelColor($x, $y);

/* Paints pixel in position 1,1 black and all neighboring 
   pixels that match the target color */
$combined->floodfillPaintImage("black", 1, $target, $x, $y, false);

/* Save the result */
$combined->writeImage("floodfillpaint_result.png");
?>
