Apply a Preset Theme to a Page

Aspose.Diagram APIs allows to apply a preset theme to get a uniform look and feel to shapes within a page, and across multiple documents. Perform the following steps in order to do this:

• Create an instance of Diagram class to load a diagram
• Get an instance of Page class to be set theme
• Assign a Preset value to the PresetTheme property of the Page instance

Apply a Preset Theme to a Page Programming Sample

// 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(VisioThemes.class);
// Load diagram
Diagram diagram = new Diagram(dataDir + "Themes1.vsdx");
//Get an instance of Page class to be set theme
Page page = diagram.getPages().get(0);
//Assign a Preset value to the PresetTheme property of the Page instance
page.setPresetTheme(PresetThemeValue.BUBBLE);
// Save diagram
diagram.save(dataDir + "SetTheme_out.vsdx", SaveFileFormat.VSDX);

Page page = diagram.getPages().get(0);
//Assign a Preset value to the PresetTheme property of the Page instance
page.setPresetTheme(PresetThemeValue.BUBBLE);
//Assign a Preset value to the PresetThemeVariant property of the Page instance
page.setPresetThemeVariant(PresetThemeVariantValue.VARIANT_3);
// Save diagram
diagram.save(dataDir + "SetTheme_out.vsdx", SaveFileFormat.VSDX);

// Load diagram
Diagram diagram = new Diagram(dataDir + "Themes1.vsdx");
//Get an instance of Shape class to be set theme
Shape shape = doc.getPages().get(0).getShapes().get(0);
//Assign a Preset value to the PresetTheme property of the Shape instance
shape.setPresetTheme(PresetThemeValue.BUBBLE);
// Save diagram
diagram.save(dataDir + "SetTheme_out.vsdx", SaveFileFormat.VSDX);
