DisplayFromClipboard Method (GdViewer)

In This Topic

Loads an image, which is currently stored in the clipboard, and then displays it in the GdViewer control. The document previously displayed in the control will automatically close.

The BeforeDocumentChange and the AfterDocumentChange events are raised just before and right after the image is displayed in the GdViewer control. Both events are only raised if the image has been successfully loaded.

Return Value

A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK. We strongly recommend always checking this status first.

Remarks

Be aware that this method loads only images previously copied into the clipboard, for other data stored in the clipboard the method will fail.

Just to remind you that both the BeforeDocumentChange and the AfterDocumentChange events are raised using this method.
