Word Documents

Displaying Word Documents

The ImGearWordDocument can be created and processed in any thread with any apartment state: STA or MTA. If it also needs to be displayed, then there are some concepts which should be taken into account:

In WPF display scale mode the document must be created in the UI thread, otherwise a System.InvalidOperationException will be thrown, stating that "The calling thread cannot access this object because a different thread owns it”. This is requirement of Windows Presentation Foundation.
In Native display scale mode, which is the default for ImageGear, there are no restrictions for displaying Word pages in a multithreaded environment.

ImageGear renders only accepted revision changes of the document; i.e., if it has "Track Changes" enabled, please make sure to accept all/required changes in the document prior to opening it with ImageGear.
