Editing Image server (section)

== Concepts ==

=== Single-source imaging ===
The proliferation of mobile devices, screen resolutions, and pixel densities has forced web designers to create an ever-increasing number of image variations.
Image servers capable of [[Single-source imaging|dynamic image resizing]] can produce the required sizes and variations on demand, eliminating repetitive work and the room for human error.

=== Declarative vs imperative ===
[[Declarative programming|Declarative]] APIs (such as RIAPI) allow the client to describe resulting characteristics of the image, such as desired size, aspect ratio, rotation, fit modes, etc. Command order is not important - ?width=200&height=100 will produce the same result as ?height=100&width=200. The server is free to coalesce compatible operations to improve performance.

[[Imperative programming|Imperative]] APIs, (such as [[Internet Imaging Protocol|IIP]] or [[International Image Interoperability Framework|IIIF]]) describe the operations to apply to the image in order, offering the user more control, but also more responsibility for calculations.
