AEM Image Processing and Best Practices by Engineering at ICF Next

Abstract

Objective

Objective of this document is to define the out of the box Image renditions and processing concepts in AEM and compare with the Image Transformation process using ACS (Adobe Consulting Services) commons library. Its pros/cons are also listed.

Image Renditions vs Image transformations

In Image renditions separate images are created and stored in DAM for each size/resolutions, whereas in transformations one high quality image is uploaded and the same is used in different sizes and resolutions and are transformed according to the need in runtime on the fly and cached in dispatcher.

More details pros/cons are mentioned in below sections.

Image Rendition

Rendition is a process of creating multiple sizes and versions of images post uploading them to DAM (Digital Asset Management). These renditions are helpful in creating thumbnails or smaller image views of large and high-resolution images which can be used in the content of the website for different purposes.
