Imagick::floodFillPaintImage

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

Imagick::floodFillPaintImageChanges 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(10050"red");
$im->newImage(10050"green");
$im->newImage(10050"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$x$yfalse);

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