The Datalogics PDF Java Toolkit is a Java Application Programming Interface (API) based on libraries developed by Adobe. PDF Java Toolkit can be used as a general-purpose PDF library like APDFL, but it provides a suite of services that extend beyond APDFL. These features include the ability to:
- Create and manage digital signatures
- Generate appearances for annotations, including barcodes
- Import data into and export data from PDF forms
- Enable PDF documents so that users can edit them in Adobe Reader and then save their changes. This allows users of Adobe Reader to access Acrobat functions, like generating dynamic barcodes.
