Image Interlacing is simply combining two images by layering one over the other with a certain opacity (usually 50%). The intention is to use the image in video, so that two images are displayed within one single frame, thereby doubling the frames-per-second without doubling the actual, physical amount of frames. Wikipedia provides a fairly decent explanation of this type of video technology: http://en.wikipedia.org/wiki/Interlaced_video .

Some sample code :

<?php

// Author: holdoffhunger@gmail.com

// Imagick Type
// ---------------------------------------------

$imagick_type = new Imagick();

// Open File
// ---------------------------------------------

$file_to_grab = "image_workshop_directory/test.jpg";

$file_handle_for_viewing_image_file = fopen($file_to_grab, 'a+');

// Grab File
// ---------------------------------------------

$imagick_type->readImageFile($file_handle_for_viewing_image_file);

// Get Rendering Intent Values
// ---------------------------------------------

$imagick_rendering_intent = $imagick_type->getImageRenderingIntent();

switch(
$imagick_rendering_intent)
{
case
'0':
$image_rendering_intent_evaluated = "Undefined";
break;

case
'1':
$image_rendering_intent_evaluated = "Saturation";
break;

case
'2':
$image_rendering_intent_evaluated = "Perceptual";
break;

case
'3':
$image_rendering_intent_evaluated = "Absolute";
break;

case
'4':
$image_rendering_intent_evaluated = "Relative";
break;
}

// Print Rendering Intent Values
// ---------------------------------------------

print("# $imagick_rendering_intent - $image_rendering_intent_evaluated");
