When working with PDF Rasters, it is often necessary turn Layers on and off within the PDF. Being able to automate this is essential.
Large organization may have hundreds of PDF's that can be reused as supplemental data and enhancing productivity by allowing the automation of their use will not be complete unless unnecessary Layers can be turned off as part of the automation process.
The alternative is to have to maintain multiple versions of the PDF files, or every time a user needs to use the PDF, they have to manually select which layers to toggle off. This is lost productivity on a large scale, for large organizations.
