Visio Dibujo Guardar Resumen

Utilizar elDiagram.Save método para guardar un dibujo Microsoft Visio. Hay sobrecargas que permiten guardar un dibujo en un archivo. El dibujo se puede guardar en cualquier formato de guardado admitido por Aspose.Diagram. Para ver la lista de todos los formatos de guardado admitidos, consulte elGuardar formato de archivo enumeración

Ahorro Visio Diagram

La clase Diagram de Aspose.Diagram API representa un dibujo Visio y los desarrolladores pueden guardar su objeto Visio diagram en cualquier formato de archivo compatible. Para guardar un archivo Microsoft Visio, simplemente use elDiagram.Savemétodo, acepta un nombre de archivo con una ruta completa o un objeto de flujo de archivo. Aspose.Diagram API infiere el formato de guardado de la extensión del archivo y también ofrece un parámetro SaveFileFormat adicional para especificar el formato del archivo de salida.

Guarde un Visio Diagram en cualquier formato de archivo compatible

Usando Aspose.Diagram API, los desarrolladores pueden guardar un Visio diagram en cualquier formato de archivo compatible como se indica a continuación: VSDX, VSDM, VSSX, VSSM, VSTX, VSTM, VDX, VSX, VTX, TIFF, PNG, BMP, EMF, JPEG, PDF, XPS, GIF, HTML, SVG, SWF and XAML

Guardando Diagram Ejemplo de programación

El siguiente ejemplo guarda un documento en un archivo.

 // Save a Visio diagram

diagram.Save(GetMyDir() + "MyOutput.vsdx", SaveFileFormat.VSDX);

Especificación de las opciones de guardado de Visio

Hay variosDiagram.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)

Este artículo proporciona un ejemplo de código que ilustra cómo usarVSTO yAspose.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.

Guardar un archivo VSD en otros formatos con VSTO

VSTO le permite programar con archivos Microsoft Visio. Para guardar un archivo en otros formatos:

  1. Cree un objeto de aplicación Visio.
  2. Haga que el objeto de la aplicación sea invisible.
  3. Cargue el diagram.
  4. Save to VDX, PDF and JPEG.
  5. Salga del objeto de aplicación Visio.

Ejemplo:

// 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();

 Guardar archivo VSD en otros formatos con Aspose.Diagram for .NET

Usando Aspose.Diagram, los desarrolladores no necesitan Microsoft Office Visio en la máquina, y pueden trabajar independientemente de Microsoft Office Automatización.

Los fragmentos de código a continuación muestran cómo:

  1. Cargue un diagram.
  2. Save the diagram to VSX, PDF and JPEG.
