Mikko Koppanen has another example of using the Imagick functionality to create an advanced image - this time, it's about adding a reflection (similar to some of the effects Apple uses in their designs).
Here is a simple example of creating a reflection of an image. The reflection is created by flipping the image and overlaying a gradient on it. Then both, the original image and the reflection is overlayed on a canvas.
Both the code and an example image are included in the post.
