Speichern Sie das Dokument Visio programmgesteuert
Visio Übersicht zum Speichern von Zeichnungen
Verwenden Sie dieDiagram.Save Methode zum Speichern einer Microsoft Visio Zeichnung. Es gibt Überladungen, die das Speichern einer Zeichnung in einer Datei ermöglichen. Die Zeichnung kann in jedem von Aspose.Diagram unterstützten Speicherformat gespeichert werden. Eine Liste aller unterstützten Speicherformate finden Sie unterSaveFileFormat Aufzählung.
Speichern Visio Diagram
Die Diagram-Klasse des Aspose.Diagram API stellt eine Visio-Zeichnung dar, und Entwickler können ihr Visio diagram-Objekt in jedem unterstützten Dateiformat speichern. Um eine Microsoft Visio-Datei zu speichern, verwenden Sie einfach dieDiagram.Save-Methode akzeptiert sie einen Dateinamen mit vollständigem Pfad oder ein Dateistromobjekt. Aspose.Diagram API leitet das Speicherformat aus der Dateierweiterung ab und bietet außerdem einen zusätzlichen SaveFileFormat-Parameter zur Angabe des Ausgabedateiformats.
Speichern Sie eine Visio Diagram in einem beliebigen unterstützten Dateiformat
Mit Aspose.Diagram API können Entwickler Visio diagram in jedem unterstützten Dateiformat speichern, wie unten aufgeführt: VSDX, VSDM, VSSX, VSSM, VSTX, VSTM, VDX, VSX, VTX, TIFF, PNG, BMP, EMF, JPEG, PDF, XPS, GIF, HTML, SVG, SWF and XAML
Diagram Programmierbeispiel speichern
Das folgende Beispiel speichert ein Dokument in einer Datei.
// Save a Visio diagram
diagram.Save(GetMyDir() + "MyOutput.vsdx", SaveFileFormat.VSDX);
Festlegen von Visio Speicheroptionen
Es gibt einigeDiagram.Save method overloads that accept a SaveOptions object. This should be an object of a class derived from the SaveOptions class. Each save format has a corresponding class that holds save options for that save format. For example, there is PdfSaveOptions for the SaveFileFormat.PDF save format.

Sometimes, developers need to save or export Visio diagrams to different file formats programmatically (like VDX, PDF, JPEG and so on).
Save VSD file to different file formats (VDX, PDF and JPEG)
Dieser Artikel enthält ein Codebeispiel, das die Verwendung veranschaulichtVSTO undAspose.Diagram for .NET to save a Microsoft Visio VSD file to a VDX file, PDF file or a JPEG file programmatically. Below are parallel code snippets for VSTO and Aspose.Diagram for .NET that explains how to save a VSD file into different file formats. You’ll notice that the Aspose.Diagram code is shorter. Feel free to use the code and change it to meet your specific needs.
Speichern einer VSD-Datei in anderen Formaten mit VSTO
Mit VSTO können Sie mit Microsoft Visio-Dateien programmieren. So speichern Sie eine Datei in anderen Formaten:
- Erstellen Sie ein Visio-Anwendungsobjekt.
- Machen Sie das Anwendungsobjekt unsichtbar.
- Laden Sie die diagram.
- Save to VDX, PDF and JPEG.
- Beenden Sie das Anwendungsobjekt Visio.
Speichern einer VSD-Datei mit VSTO-Programmierbeispiel
Beispiel:
// For complete examples and data files, please go to https://github.com/aspose-diagram/Aspose.Diagram-for-.NET | |
// The path to the documents directory. | |
string dataDir = RunExamples.GetDataDir_KnowledgeBase(); | |
// Create Visio Application Object | |
Visio.Application vsdApp = new Visio.Application(); | |
// Make Visio Application Invisible | |
vsdApp.Visible = false; | |
// Create a document object and load a diagram | |
Visio.Document vsdDoc = vsdApp.Documents.Open(dataDir + "Drawing1.vsd"); | |
// Save the VDX diagram | |
vsdDoc.SaveAs(dataDir + "SaveDiagramToVDXwithVSTO_out.vdx"); | |
// Save as PDF file | |
vsdDoc.ExportAsFixedFormat(Visio.VisFixedFormatTypes.visFixedFormatPDF, | |
dataDir + "SaveDiagramToPDFwithVSTO_out.pdf", Visio.VisDocExIntent.visDocExIntentScreen, | |
Visio.VisPrintOutRange.visPrintAll, 1, vsdDoc.Pages.Count, false, true, | |
true, true, true, System.Reflection.Missing.Value); | |
Visio.Page vsdPage = vsdDoc.Pages[1]; | |
// Save as JPEG Image | |
vsdPage.Export(dataDir + "SaveDiagramToJPGwithVSTO_out.jpg"); | |
// Quit Visio Object | |
vsdApp.Quit(); |
Speichern von VSD-Dateien in anderen Formaten mit Aspose.Diagram for .NET
Mit Aspose.Diagram brauchen Entwickler Microsoft Office Visio nicht in der Maschine und können unabhängig von Microsoft Office Automation arbeiten.
Die folgenden Code-Snippets zeigen, wie Sie:
- Laden Sie eine diagram.
- Save the diagram to VSX, PDF and JPEG.
