0 1 1 minute read

The Imagick::setImageIterations() function is an inbuilt function in PHP which is used to set the image iterations. The iteration here actually means for how many times the frames should repeat themselves.

Syntax:

bool Imagick::setImageIterations( int $iterations )

Parameters: This function accepts a single parameter $iterations which holds the number of iterations. Set to 0 to make it loop forever.

Return Value: This function returns TRUE on success.

Exceptions: This function throws ImagickException on error.

Below programs illustrate the Imagick::setImageIterations() function in PHP:

Program 1:

<?php 
  
// Create a new imagick object 
$imagickAnimation = new Imagick( 
'https://media.zambiatek.com/wp-content/uploads/20191120143630/newanimated.gif'); 
  
foreach ($imagickAnimation as $frame) { 
  
    // Add delay of 3 seconds 
    $frame->setImageDelay(300); 
} 
  
// Set the interations 
$imagickAnimation = $imagickAnimation->coalesceImages(); 
$imagickAnimation->setImageIterations(1); 
  
// Display the image 
header("Content-Type: image/gif"); 
echo $imagickAnimation->getImagesBlob(); 
?> 

Output:

Program 2:

<?php 
  
// Create a new imagick object 
$imagickAnimation = new Imagick( 
'https://media.zambiatek.com/wp-content/uploads/20191120143630/newanimated.gif'); 
  
// Set the interations to 0 (infinite loop) 
$imagickAnimation = $imagickAnimation->coalesceImages(); 
$imagickAnimation->setImageIterations(0); 
  
// Display the image 
header("Content-Type: image/gif"); 
echo $imagickAnimation->getImagesBlob();
