Locking WordArt Watermark

Aspose.Cells APIs allow adding WordArt watermarks on the worksheet in a way that the WordArt becomes an object that can be moved and positioned on the worksheet. It is also possible to lock the WordArt object for any interaction such as editing, movement & selection. This article explains the usage of Shape.setLockedProperty method to lock a few aspects of the watermark.

Locking WordArt Watermark

Aspose.Cells APIs allow locking certain aspects of the watermark so that the user interaction could be limited or completely blocked. The following code snippet demonstrates the usage of Aspose.Cells for Java API to create a watermark for each worksheet in the loaded spreadsheet and lock selection, movement, editing, and re-sizing of the watermark.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
// The path to the documents directory.
String dataDir = Utils.getDataDir(LockWordArtWatermark.class);

// Instantiate a new Workbook
Workbook workbook = new Workbook();

// Get the first default sheet
Worksheet sheet = workbook.getWorksheets().get(0);

// Add Watermark
Shape wordart = sheet.getShapes().addTextEffect(MsoPresetTextEffect.TEXT_EFFECT_1, "CONFIDENTIAL",
		"Arial Black", 50, false, true, 18, 8, 1, 1, 130, 800);

// Get the fill format of the word art
FillFormat wordArtFormat = wordart.getFill();

// Set the color
wordArtFormat.setOneColorGradient(Color.getRed(), 0.2, GradientStyleType.HORIZONTAL, 2);

// Set the transparency
wordArtFormat.setTransparency(0.9);

// Make the line invisible
wordart.setHasLine(false);

// Lock Shape Aspects
wordart.setLocked(true);
wordart.setLockedProperty(ShapeLockType.SELECTION, true);
wordart.setLockedProperty(ShapeLockType.SHAPE_TYPE, true);
wordart.setLockedProperty(ShapeLockType.MOVE, true);
wordart.setLockedProperty(ShapeLockType.RESIZE, true);
wordart.setLockedProperty(ShapeLockType.TEXT, true);

// Save the file
workbook.save(dataDir + "output.xls");
