Методы изображения и глобальные методы

Класс Imagick имеет возможность удерживать и обрабатывать несколько изображений одновременно. Это достигается за счёт внутреннего стека, в котором существует указатель, указывающий на текущее изображение. Некоторые функции работают со всеми изображениями в классе Imagick, но всё-таки, большинство работает только с текущим изображением во внутреннем стеке. По соглашению, имена методов могут содержать слово Image для обозначения того, что они влияют только на текущее изображение в стеке.

Методы класса

Здесь приведён список наиболее используемых методов, объединённых в группы по назначению:

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

("Content-Type: image/{$Imagick->getImageFormat()}");
$data = $Imagick->getImageBlob ();
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.


= 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:
