Detect Animations

Check the Current Image Instance for Animation

public Image::isAnimated(): bool

Returns true if the image is animated. Otherwise false is returned.

Examples

use Intervention\Image\ImageManager;
use Intervention\Image\Drivers\Gd\Driver;

// create new manager instance with desired driver
$manager = new ImageManager(Driver::class);

// true
$result = $manager->read('images/animation.gif')->isAnimated();

Editing Animations

Changing the Animation Frames

public Image::sliceAnimation(int $offset, null|int $length = null): ImageInterface

Extract animation frames based on given values and discard the rest. The offset parameter can be used to set the starting point of the new animation; all frames before the offset are discarded. The length parameter is optional. It specifies how many frames to read after the offset. By default, all frames up to the end of the animation are read.

Parameters

Name Type Description
offset integer Starting point of the new animation
length null or integer Frames to read after the offset (optional)

Examples

use Intervention\Image\ImageManager;
use Intervention\Image\Drivers\Gd\Driver;

// create new manager instance with desired driver
$manager = new ImageManager(new Driver());

// reading an animated gif
$image = $manager->read('images/animation.gif');

// discard the first 20 frames and read the following 10 frames as new animation
$image = $image->sliceAnimation(20, 10);

Reading the Animation Iteration Count

public Image::loops(): int

Read the count of iterations of the animated image. 0 means the image loops continuously.

Examples

use Intervention\Image\ImageManager;
use Intervention\Image\Drivers\Imagick\Driver;

// create new manager instance with desired driver
$manager = new ImageManager(new Driver());

// reading an animated gif
$image = $manager->read('images/animation.gif');

// return animation iteration count
$count = $image->loops();

Changing the Animation Iteration Count

public Image::setLoops(int $count): ImageInterface

Change the number of iterations the animation should loop over. Set to 0 to loop continuously.

Parameters

Name Type Description
count integer Number of animation iterations

Examples

use Intervention\Image\ImageManager;
use Intervention\Image\Drivers\Gd\Driver;

// create new manager instance with desired driver
$manager = new ImageManager(new Driver());

// reading an animated gif
$image = $manager->read('images/animation.gif');

// animation should only run once
$image = $image->setLoops(1);

Removing Animation

public Image::removeAnimation(int|string $position = 0): ImageInterface

Discards all animation frames of the current image instance except the one at the given position. Turns an animated image into a static one.

It is possible to specify the position as integer and string values. With the former, the exact position passed is searched for, while string values must represent a percentage value between 0% and 100% and the respective frame position is only determined approximately.

If an integer is specified, the method throws an exception if the respective position is not found. This does not happen with percentage values.

Parameters

Name Type Description
position integer or string Position of the frame that will be left.

Examples

use Intervention\Image\ImageManager;
use Intervention\Image\Drivers\Gd\Driver;

// create new manager instance with desired driver
$manager = new ImageManager(new Driver());

// reading an animated gif
$image = $manager->read('images/animation.gif');

// Turn the animation into a static image displaying the frame at position 5
$image = $image->removeAnimation(5);

// do the same by choosing animation frame at 25% of the whole animation
$image = $image->removeAnimation('25%');
