使用艺术字为电子表格添加特殊文本效果。例如，在文件顶部拉伸标题、修饰文本并使文本适合预设形状，或将文本作为背景水印应用于 Excel 工作表。艺术字成为一个对象，您可以在电子表格中移动或定位以添加装饰。
下面的示例演示如何添加艺术字形状来为工作表设置背景水印。
运行代码后，输出文件包含淡红色艺术字水印。

Aspose.Cells.Drawing.Shape wordart = sheet.Shapes.AddTextEffect(MsoPresetTextEffect.TextEffect1,
"CONFIDENTIAL", "Arial Black", 50, false, true
, 18, 8, 1, 1, 130, 800);
//Get the fill format of the word art
