The above diagram shows the internal arrangement of the layers of the PDF-XChange Editor SDK and depending on your license type you will have access to some or all of its functionality. Essentially there are only 2 distinct License types.
Firstly the PDF-XChange Editor SDK license covers the entire range of functionality as represented to your users by the rich UI of the PDF-XChange Editor embedded within your own applications and controlled either in part or entirely directly by the interaction of the End User with the interface offered or by your application and the functions offered and in your programmatic control. The full Editor SDK also allows you to access and offer the NON-UI based functionality of the PDF-XChange Core API and all its creation and manipulation features.
Secondly the PDF-XChange Core API license provides access to all the NON-UI based functionality available for the creation and manipulation of files - but does not allow you to utilize or offer to your uses in anyway the UI functionality of the PDF-XChange Editor User Interface.
Also please note that this SDK is Royalty based via the purchase of Client Distribution License Packs (CDLP's) and whilst you can fully develop and test all your applications using the Evaluation SDK's prior to purchase to ensure satisfaction, prior to distribution of any application making use of this SDK to any end user client - the pre-purchase of CDLP's is required.
PDF-XChange SDK consists of several infrastructure libraries:
- PDF Editor Layer
- PDF Core Layer
- PDF Structures Layer
- UI Layer
