Save a Filter Graph as XML
Note GraphEdit implements a preliminary version of this feature. This feature may change. Future releases are not guaranteed to support it.
To save a filter graph as an XML file, perform the following steps:
On the File menu, click Save As XML (.XGR)....
In the Save As dialog box, enter the name of the file.
Click Save.
XML graph files use the extension .xgr.
Applications should not use this format as a persistence format. It is designed for testing and debugging purposes only.
非高版本graphedit在vista下会有更多问题,比如不能正常打开EVR
