Image methods and global methods

The Imagick class has the ability to hold and operate on multiple images simultaneously. This is achieved through an internal stack. There is always an internal pointer that points at the current image. Some functions operate on all images in the Imagick class, but most operate only on the current image in the internal stack. As a convention, method names can contain the word Image to denote they affect only the current image in the stack.

Class Methods

Because there are so many methods, here is a handy list of methods, somewhat reduced to their general purpose:

Users looking to save  with these functions should know it can be done easily, for example

<?php
header ("Content-Type: image/{$Imagick->getImageFormat()}");
$data = $Imagick->getImageBlob ();
echo $data;
file_put_contents ('test.png', $data);
?>

That would display the image, and then save it to test.png. Such things are helpful especially when you need to reload images after creating them or save for later. :)

When using this library with PDFs, the term "image" applies to a page where the pointer begins at the last page of the document.

<?php

$document = new Imagick('myPdf.pdf'); //2 page PDF

$document->getNumberImages(); //returns 2

var_dump($document->hasNextImage()); //returns false - remember, we're on the last page
var_dump($document->hasPreviousImage()); //returns true

?>

If you need to do more than generate thumbnails from a PDF, use XPDF: http://www.foolabs.com/xpdf/home.html
