Imagick::setImageDelay - Sets the image delay

SYNOPSIS

       bool Imagick::setImageDelay (int  $delay)

DESCRIPTION

	Sets  the  image delay. For an animated image this is the amount of time that this frame of the image should be displayed for, before dis-
       playing the next frame.

	The delay can be set individually for each frame in an image.

PARAMETERS

	      o $delay
		- The amount of time expressed in 'ticks' that the image should be displayed for. For animated GIFs there are 100 ticks  per  sec-
		ond, so a value of 20 would be 20/100 of a second aka 1/5th of a second.

RETURN VALUES

	Returns TRUE on success.

ERRORS
/EXCEPTIONS
	Throws ImagickException on error.

EXAMPLES

       Example #1

	      Modify animated Gif with Imagick.setImageDelay(3)

	      <?php

	      // Modify an animated Gif so that it's frames are played at a variable speed,
	      // varying between being shown for 50ms down to 0ms, which will cause the frame
	      // to be skipped in most browsers.
	      $imagick = new Imagick(realpath("Test.gif"));
	      $imagick = $imagick->coalesceImages();

	      $frameCount = 0;

	      foreach ($imagick as $frame) {
		  $imagick->setImageDelay((($frameCount % 11) * 5));
		  $frameCount++;
	      }

	      $imagick = $imagick->deconstructImages();

	      $imagick->writeImages("/path/to/save/output.gif", true);

	      ?>
