Format Visio Pages

Aspose.Diagram for Java API allows developers to format pages of a Visio Diagram file. Applying Stylesheets is one such method to format Visio pages.

Apply Stylesheets to Visio Page

Aspose.Diagram for Java API lets you format a Visio page using Stylesheets. You can define a stylesheet and add it to the Visio document’s stylesheet collection. The ApplyStyle method of Page class lets you apply the defined stylesheet to the page as shown in the following code 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.getSharedDataDir(ReadDiagramFile.class) + "Diagrams/";
// Open the stream. Read only access is enough for Aspose.Diagram to
// load a diagram.
InputStream stream = new FileInputStream(dataDir + "ReadDiagramFile.vsd");

// load diagram
Diagram vsdDiagram = new Diagram(stream);
//Define a new StyleSheet
StyleSheet st = new StyleSheet();
st.setID(vsdDiagram.getStyleSheets().getCount()+1);
com.aspose.diagram.Char ch = new com.aspose.diagram.Char();
ch.getColor().setValue("#00ff00");
ch.setIX(0);
st.getChars().add(ch);
		
st.getLine().getLineColor().setValue("#ff0000");
st.getLine().getLinePattern().setValue(1);
		
st.getLine().getLineWeight().setValue(0.01);
st.getFill().getFillForegnd().setValue("#0000ff");
st.getFill().getFillPattern().setValue(1);
st.getFill().getShdwPattern().setValue(0);

//Add the stylesheet to Stylesheets collection
vsdDiagram.getStyleSheets().add(st);

for (Shape shape: (Iterable<Shape>)vsdDiagram.getPages().get(0).getShapes())
{
    shape.getLine().getLinePattern().setValue(1);
    shape.getFill().getFillPattern().setValue(1);
}

//Apply the stylesheet
vsdDiagram.getPages().get(0).applyStyle(st.getID(), st.getID(), st.getID());
