ImageGear Professional for Windows ActiveX
General Objects

This section describes a group of objects that provide access to PDF document's components such as metadata, pages, fonts, etc. These objects and methods allow applications to manipulate the PDF content and data. Some of the objects allow you to work with host system fonts and encodings, and the supplementary objects such as IGPDFAtom Object and IGPDFStream Object used to simplify and optimize working with PDF content.

The following table contains general objects and their descriptions supported by the ImageGear PDF component:

IGPDFAction Object PDF action object, which is a task that performs when a user clicks on a link or a bookmark.
IGPDFAtom Object Atom - a hashed token used in place of strings to optimize performance (it is much faster to compare Atoms than strings). Many methods use Atoms.
IGPDFAuthEventParams Object Parameters used in the authorization event.
IGPDFBookmark Object PDF bookmark object, which allows the user to navigate interactively from one part of the document to another.
IGPDFDestination Object PDF destination object, which represents a particular view of a page in a document.
IGPDFDoc Object Document - the underlying PDF representation of a document. Through PDF Document, your application can perform most of the Edit Pages operations (delete, replace, and so on). Thumbnails can be created and deleted through this object. You can set and retrieve document information fields through this object as well.
IGPDFLayer Object PDF layer object represents a named object whose state can be toggled in a UI to affect changes in visibility of content.
