Append the resulting image to the imagelist in "example". The assoc, flatten, flatten!, join, pack, and rassoc methods are notĪdd noise to a model image. ![]() If you need to replace images inĪn imagelist with non-image objects, convert the imagelist to an array with the to_a method, then modify the array. If you call collect! on an imagelist you should make sure that the members of the imagelist remain images. Most of the time RMagick will raise an ArgumentError exception. The following table lists the methods that doĪdding anything other than a image to an imagelist has undefined results. If the method deletes the current image, the scene number is set to the last image in the list. If the method moves the current image to a new position, the method updates the scene number to the Most array methods keep the current image current. List, and if the imagelist contains no images the scene number will be nil.Īrray methods that would normally return an array return an ImageList. ![]() The scene number will never exceed the number of images in the Typically these methods also update the scene number. Just look for COMPOSITE_* constants in the "Constants" section.ImageList delegates many methods to Array, so you can manipulate the images in an imagelist using almost all of the methodsĭefined in Array. You can use the reflection API of PHP5 to get the list of them. It can be given either as a constant or as the integer value of that constant. And here comes the second argument of the compositeImage method. Not only can we put them in specific order, but we can also choose the way we want them to interfere with each other. The images we are composing together are separate layers. "\n" Īlso a couple more words on the Imagick::COMPOSITE_DEFAULT argument. '/face_and_glasses.jpg' ) Įcho 'Caught exception: '. Let's merge all layers (it is not mandatory). $face -> compositeImage ( $glasses, Imagick :: COMPOSITE_DEFAULT, 10, 20 ) Let's put the glasses on (10 pixels from left, 20 pixels from top of face). Let's presume, that we have a directory in our filesystem, which contains our program and the two images we want to operate on. The Imagick class utilises the exception handling model introduced in PHP5 and thus we will do that as well. ![]() Here is an example on how to compose two images into a single one.
