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.Save, acepta un nombre de archivo con la 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 and XAML

Guardando Diagram Ejemplo de programación

El siguiente ejemplo guarda un documento en un archivo.

// For complete examples and data files, please go to https://github.com/aspose-diagram/Aspose.Diagram-for-Java
// The path to the documents directory.
String dataDir = Utils.getDataDir(SaveVisioDiagram.class);
// load an existing Visio diagram
Diagram diagram = new Diagram(dataDir + "Drawing1.vsdx");
// save diagram using the direct path
diagram.save(dataDir + "SaveVisioDiagram_Out.vsdx", SaveFileFormat.VSDX);
ByteArrayOutputStream dstStream = new ByteArrayOutputStream();
// save diagram in the stream
diagram.save(dstStream, SaveFileFormat.VSDX);
// In you want to read the result into a Diagram object again, in Java you need to get the
// data bytes and wrap into an input stream.
ByteArrayInputStream srcStream = new ByteArrayInputStream(dstStream.toByteArray());

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.
