Arbeta med OLE-objekt

Manipulera programmeringsexemplet för inbäddade OLE-objekt

ObjectData-egenskapen i klassen ForeignData tillåter utvecklare att manipulera med befintliga OLE-objekt i Visio diagram. Det här hjälpämnet visar hur utvecklare kan hämta ett OLE-objekt i Word-dokumentet, redigera det med hjälp avAspose.Words for Java API, och spara sedan tillbaka som ett OLE-objekt i Visio diagram.

// For complete examples and data files, please go to https://github.com/aspose-diagram/Aspose.Diagram-for-Java
String dataDir = Utils.getDataDir(ManipulateEmbeddedOLEObjects.class);
System.out.println(dataDir);
// load a Visio diagram
Diagram diagram = new Diagram(dataDir + "Drawing1.vsdx");
// get page of the Visio diagram by name
Page page = diagram.getPages().getPage("Page-1");
// get shape of the Visio diagram by ID
Shape OLE_Shape = page.getShapes().getShape(2);
// filter shapes by type Foreign
if (OLE_Shape.getType() == TypeValue.FOREIGN) {
if (OLE_Shape.getForeignData().getForeignType() == ForeignType.OBJECT) {
ByteArrayInputStream Ole_stream = new ByteArrayInputStream(OLE_Shape.getForeignData().getObjectData());
// get format of the OLE file object
com.aspose.words.FileFormatInfo info = com.aspose.words.FileFormatUtil.detectFileFormat(Ole_stream);
if (info.getLoadFormat() == com.aspose.words.LoadFormat.DOC
|| info.getLoadFormat() == com.aspose.words.LoadFormat.DOCX) {
// modify an OLE object using Aspose.Words API
Document doc = new Document(new ByteArrayInputStream(OLE_Shape.getForeignData().getObjectData()));
doc.getRange().replace("testing", "Aspose", false, true);
ByteArrayOutputStream outStream = new ByteArrayOutputStream();
doc.save(outStream, com.aspose.words.SaveFormat.DOCX);
// replace an OLE object
OLE_Shape.getForeignData().setObjectData(outStream.toByteArray());
}
}
}
// save Visio diagram
diagram.save(dataDir + "modified.vsdx", SaveFileFormat.VSDX);
