Set Orientation and Control the Export of Hidden Visio Pages on Saving

Change a Visio Page Layout to Portrait or Landscape

Aspose.Diagram for .NET API allows developers to set the orientation of the Visio drawing page programmatically. This help topic explains how to accomplish this task.

Aspose.Diagram for .NET API has the Page class that represents a Visio drawing page. The PageSheet property exposed by the Page class also exposes the print properties. The PrintPageOrientation field of the print properties allows to rotate the page. It offers three options as Portrait, Landscape and same as on the printer. The PrintPageOrientation field can be set programmatically using Aspose.Diagram API.

This example work as follows:

1. Load an existing Visio diagram into the Diagram class object.
2. Extract a Visio page
3. Set its orientation as Portrait, Landscape or same as on the printer.
4. Save the Visio diagram.

Set Orientation Programming Sample

The code example below shows how to set the orientation of the Visio page.

// 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_VisioPages();

// Initialize the new visio diagram
Diagram diagram = new Diagram(dataDir + "Drawing1.vsdx");

// Get Visio page
Aspose.Diagram.Page page = diagram.Pages.GetPage("Flow 1");
// Page orientation
page.PageSheet.PrintProps.PrintPageOrientation.Value = PrintPageOrientationValue.Landscape;
// Save Visio
diagram.Save(dataDir + "SetPageOrientation_out.vsdx", SaveFileFormat.VSDX);

Control the Export of Hidden Visio Pages on Saving

Aspose.Diagram for .NET API allows developers to include or exclude hidden Visio pages on saving diagram to PDF, HTML, Image (PNG, JPEG, GIF), SVG, and XPS files. Even they may hide Visio pages using Aspose.Diagram API because its option is already available through the cell UIVisibility in the page ShapeSheet.

Hide a Page in the Visio Diagram and Set Export Option

Aspose.Diagram for .NET API has the Page class that represents a Visio drawing page. The PageSheet property exposed by the Page class also exposes the page properties. The UIVisibility field of the page properties allows to hide the page. Developers can then use ExportHiddenPage property which is added in the SVGSaveOptions, XPSSaveOptions, ImageSaveOptions, HTMLSaveOptions and PdfSaveOptions classes.

Set the Export Option for PDF

The code below shows how to set save options before saving a diagram to PDF format.

// 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_Intro();

// Load an existing Visio
Diagram diagram = new Diagram(dataDir + "Drawing1.vsdx");
// Get a particular page
Page page = diagram.Pages.GetPage("Flow 2");
// Set Visio page visiblity
page.PageSheet.PageProps.UIVisibility.Value = BOOL.True;

// Initialize PDF save options
PdfSaveOptions options = new PdfSaveOptions();
// Set export option of hidden Visio pages
options.ExportHiddenPage = false;

// Save the Visio diagram
diagram.Save(dataDir + "ExportOfHiddenVisioPagesToPDF_out.pdf", options);

Set the Export Option for HTML

The code below shows how to set save options before saving a diagram to HTML format.

// 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_Intro();

// Load an existing Visio
Diagram diagram = new Diagram(dataDir + "Drawing1.vsdx");
// Get a particular page
Page page = diagram.Pages.GetPage("Flow 2");
// Set Visio page visiblity
page.PageSheet.PageProps.UIVisibility.Value = UIVisibilityValue.Visible;

// Initialize PDF save options
HTMLSaveOptions options = new HTMLSaveOptions();
// Set export option of hidden Visio pages
options.ExportHiddenPage = false;
// Set export option of comments
options.IsExportComments = false;

// Save the Visio diagram
diagram.Save(dataDir + "ExportOfHiddenVisioPagesToHTML_out.html", options);

Set the Export Option for Image

The code below shows how to set save options before saving a diagram to image format.

// 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_Intro();

// Load an existing Visio
Diagram diagram = new Diagram(dataDir + "Drawing1.vsdx");
// Get a particular page
Page page = diagram.Pages.GetPage("Flow 2");
// Set Visio page visiblity
page.PageSheet.PageProps.UIVisibility.Value = UIVisibilityValue.Visible;

// Initialize PDF save options
ImageSaveOptions options = new ImageSaveOptions(SaveFileFormat.JPEG);
// Set export option of hidden Visio pages
options.ExportHiddenPage = false;
// Set export option of comments
options.IsExportComments = false;

// Save the Visio diagram
diagram.Save(dataDir + "ExportOfHiddenVisioPagesToImage_out.jpeg", options);

Set the Export Option for SVG

The code below shows how to set save options before saving a diagram to SVG format.

// 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_Intro();

// Load an existing Visio
Diagram diagram = new Diagram(dataDir + "Drawing1.vsdx");
// Get a particular page
Page page = diagram.Pages.GetPage("Flow 2");
// Set Visio page visiblity
page.PageSheet.PageProps.UIVisibility.Value = UIVisibilityValue.Visible;

// Initialize PDF save options
SVGSaveOptions options = new SVGSaveOptions();
// Set export option of hidden Visio pages
options.ExportHiddenPage = false;
// Set export guide shapes 
options.ExportGuideShapes = false;
// Set save format
options.SaveFormat = Aspose.Diagram.SaveFileFormat.SVG;
// Set SVG fit to view port
options.SVGFitToViewPort = true;
// Set export element as Rectangle
options.ExportElementAsRectTag = true;


// Save the Visio diagram
diagram.Save(dataDir + "ExportOfHiddenVisioPagesToSVG_out.svg", options);

Set the Export Option for XPS

The code below shows how to set save options before saving a diagram to XPS format.

// 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_Intro();

// Load an existing Visio
Diagram diagram = new Diagram(dataDir + "Drawing1.vsdx");
// Get a particular page
Page page = diagram.Pages.GetPage("Flow 2");
// Set Visio page visiblity
page.PageSheet.PageProps.UIVisibility.Value = BOOL.True;

// Initialize PDF save options
XPSSaveOptions options = new XPSSaveOptions();
// Set export option of hidden Visio pages
options.ExportHiddenPage = false;

// Save the Visio diagram
diagram.Save(dataDir + "ExportOfHiddenVisioPagesToXPS_out.xps", options);
