Imagick::floodFillPaintImage — Changes the color value of any pixel that matches target
Description
$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
TRUEpaints 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");
?>
