Defining custom-size downloadable previews (Quick Renditions)
Quick Renditions are predefined sizes that you can set as an administrator and will let users download a preview of the image in the DAM system with a single click.
Although somewhat similar to processing profiles, Quick Renditions will only create a resized copy of the original asset and deliver to the client with an optional watermark - no additional processing can be used with Quick Renditions. Still, it offers a convenient way to define sizes and assign a label to them so users can quickly understand its use.
As an administrator you can create a collection of Quick Renditions and assign these to an archive to let users choose from the different sizes you've defined.
Power tip: If you're building an integration with FotoWeb using the API, using QuickRenditions is the preferred method to request custom size previews!
Creating Quick Renditions
To create a new collection of Quick Renditions, open the site configuration (Tools - Manage site), expand the Workflows tab and select the Quick renditions node.
Now click on the Add button to create a new collection. First, name the collection and optionally enter a description. Then click on the Add size button to add the different rendition sizes you would like.
Each size can have a descriptive name - this is what the user will see in the user interface. Then choose a size - a preview has to be in the range 50 to 8192 pixels.
You can also customize the order of the sizes you've defined by moving them up or down in the list.
Watermarking a Quick Rendition
If you like, you can assign a watermark to the renditions. If you want to watermark all the renditions in a collection, make sure you set the watermark individually for all the sizes you define.
Tip: You can upload custom watermarks to the server and use them for Quick Renditions and processing profiles. On the Manage Site page, click on the Watermarks node in the panel on the left hand side and then click on the Upload button in the top right corner. When creating a watermark, you can achieve transparency by making sure those areas have a color value of 128 in R, G and B channels.
When you're done adding sizes click on the Save button to close the dialog and store the collection.
Assigning the Quick Renditions to an archive
When you've created a quick rendition collection, you need to assign it to the archive where it should be used.
Open the properties of that archive and go to the Export tab. Then choose the collection you created in the Quick Renditions section.
