Spara Visio dokument programmatiskt
Visio Ritning Spara Översikt
Använd[Diagram.Save](https://reference.aspose.com/diagram/java/com.aspose.diagram/diagram#save(java.lang.String,%20int) metod för att spara en Microsoft Visio ritning. Det finns överbelastningar som gör det möjligt att spara en ritning till fil. Ritningen kan sparas i valfritt sparformat som stöds av Aspose.Diagram. För listan över alla sparade format som stöds, seSaveFileFormat Enum.
Sparar Visio Diagram
Klassen Diagram i Aspose.Diagram API representerar en Visio-ritning och utvecklare kan spara dess Visio diagram-objekt i vilket filformat som helst. För att spara en Microsoft Visio fil, använd helt enkeltDiagram.Save-metoden, accepterar den ett filnamn med den fullständiga sökvägen eller ett filströmsobjekt. Aspose.Diagram API härleder sparaformatet från filtillägget och erbjuder även en extra SaveFileFormat-parameter för att ange utdatafilformat.
Spara ett Visio Diagram i valfritt filformat som stöds
Genom att använda Aspose.Diagram API kan utvecklare spara en Visio diagram i vilket filformat som helst som stöds enligt listan nedan: VSDX, VSDM, VSSX, VSSM, VSTX, VSTM, VDX, VSX, VTX, TIFF, PNG, BMP, EMF, JPEG, PDF, XPS, GIF, HTML, SVG and XAML
Sparar Diagram Programmeringsexempel
Exemplet nedan sparar ett dokument till en fil.
// 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()); |
Ange Visio Spara alternativ
Det finns flera[Diagram.Save](https://reference.aspose.com/diagram/java/com.aspose.diagram/diagram#save(java.lang.String,%20int)metodöverbelastningar som accepterar ett SaveOptions-objekt. Detta bör vara ett objekt av en klass som härrör från klassen SaveOptions. Varje spara-format har en motsvarande klass som innehåller spara-alternativ för det spara-formatet, till exempel finns det PdfSaveOptions för SaveFileFormat.PDF spara-format.
