The Amyuni PDF Creator was designed for two main purposes:
Viewing, editing and printing PDF documents.
Creating reports, forms and general documents directly in PDF format.
The ActiveX controls that are part of the PDFCreator can be integrated into most development environments to provide the final user with advanced PDF document management capabilities.
The PDFCreator control can be in one of four modes:
Design mode.
Run or Compiled mode.
Annotation mode.
Print preview mode.
When a blank document is first created, the control is in design mode. The user or developer can add objects to the document, delete objects, modify object properties and do all editing operations allowed by the PDF Creator control.
When an existing PDF document is opened, two things can happen:
The PDF document was generated by the PDFCreator and contains all design information generated by the control. In this case, the document is opened in the same state as when it was saved, i.e. either Design, Run, Annotate or PrintPreview modes.
The PDF document was generated by another tool such as the Amyuni PDF Converter. In this case, the document is opened immediately in Run mode. The document can only be read or printed and if the user has enough rights on the document, the user can switch the document to annotation or design mode and edit it using the PDFCreator interface.
The documents created by the PDFCreator can contain fields with formulas or data coming from a database. Compiling the document instructs the PDFCreator to compute those formulas and fetch information from the database. Once compiled, the document switches to Run mode and only the fields or objects defined as Editable can be modified in Run mode.
Version 2.0 of the PDFCreator added the Annotation mode as one of the PDFCreator modes of operation. In Annotation mode, the contents of the original document cannot be modified; the user can only add or modify PDF annotations such as Text, Line, Highlighter or Sticky note annotations.
