Areas of use

All corporate areas

The 3-Heights™ PDF Viewer is an independent and lean component. It is generally suitable for use in all corporate areas to integrate document viewing into an application and customize the layout, functionalities and permissions. It preserves memory resources, reduces load times and minimizes security risks.


Using the PDF Viewer, a user can easily create, edit and save annotations. Properties such as text or color can be predefined (using events), so that company guidelines can be enforced or workflows be optimized. This also allows for implementing a permission check, so that e.g. only privileged users can create new annotations or editing is disabled for read-only documents.
