The batch processor in RealWorld Photos is capable of creating and providing the necessary infrastructure for droplets.
Droplet is a tiny executable file that can be placed on desktop (or elsewhere) and if files are dragged and dropped on it, a predefined operation is applied to the files. For example, it is possible to resize, watermark, or automatically adjust exposition of the dropped files.
Droplets have two main groups of users:
The simplest usage scenario consist of just dragging and dropping files (or folders) on the droplet's icon. The droplet works best if it is placed on an easily accessible place - for example Desktop or the Quick Launch bar.
The droplet will display a window with progress report and eventually encountered errors. Some droplets may display additional windows asking the user to make a choice (for example a resizing droplet may ask for the dimensions to resize to).
Droplets may be configured to overwrite the source files or to (by default) produce copies in a new folder. This folder can be automatically opened after the droplet finished processing and user can move the files from there.
To create a droplet, start RealWorld Photos and switch to the Batch Mode page. Select the batch operation of your choice and click the Create droplet toolbar button. Read the guide on creating droplets for more information.
