Imagick: : setImageTicksPerSecond

Contents

(PECL imagick 2.0.0)

Imagick::setImageTicksPerSecond — Sets the image ticks-per-second

Description

Imagick::setImageTicksPerSecond ( int $ticks_per_second ) : bool

Adjust the amount of time that a frame of an animated image is displayed for.

Note:

For animated GIFs, this function does not change the number of 'image ticks' per second, which is always defined as 100. Instead it adjusts the amount of time that the frame is displayed for to simulate the change in 'ticks per second'.

For example, for an animated GIF where each frame is displayed for 20 ticks (1/5 of a second) when this method is called on each frame of that image with an argument of 50 the frames are adjusted to be displayed for 40 ticks (2/5 of a second) and the animation will play at half the original speed.

// Modify an animated gif so the first half of the gif is played at half the
// speed it currently is, and the second half to be played at double the speed

$frameCount = 0;

foreach ($imagick as $frame) {
    $imagick->setImageTicksPerSecond(50);
    
    if ($frameCount < ($totalFrames / 2)) {
        // Modify the frame to be displayed for twice as long as it currently is
        $imagick->setImageTicksPerSecond(50);
    } else {
        // Modify the frame to be displayed for half as long as it currently is
