Presets enable you to construct simple aliases for complex transformation sequences.
Assume you wish to resize an image to 500px wide and blur it.
To accomplish this, use the resize transformation with the width parameter and then the blur transformation in the URL, as shown below.
As you can see, the
p marker is used to designate the

The below image uses p:thumbnail~t.grey() as its transformation pattern.
The following video tutorial demonstrates how to set up a preset for quicker image workflows.
