With the help of an external application (ImageMagick) or the PHP image library (GD), eZ Publish is capable of generating different variations of an uploaded image. This feature is typically useful when there is a need to show the same image in different ways (for example different sizes).

When an image variation is created (and the default settings are used), eZ Publish will generate a reference image using the file that was uploaded. The reference image is then used to generate the different image variations (small, medium, large and rss) on-demand using the constraints specified in the table above. The generated variations will be cached on the filesystem.

Depending on the image system used, eZ Publish is capable of generating image variations that consist of much more than just scaling. For example, it is possible to generate sharpened grayscale images for the thumbnails of a photo album.

Text to image generation

eZ publish come with the ability to creates an image that contains the input text rendered using a truetype font. An eZ Publish distribution comes with a small collection of truetype fonts that are used by the default styles.
