可以使用Aspose.Cells為電子表格添加特殊的藝術字效果。例如,可以拉伸標題,修飾文本,并使文本符合預設形狀,或者是為圖表添加水印效果。

在下面的例子中將演示如何使用Aspose.Cells提供的簡單API在圖表的圖形區添加藝術字水印效果。

示例代碼：

Java

String filePath = "F:/Shak-Data-RW/Downloads/source.xls";

//Instantiate a new workbook.
//Open the existing excel file.
Workbook workbook = new Workbook(filePath);

//Get the chart in the first worksheet.
com.aspose.cells.Chart chart = workbook.getWorksheets().get(0).getCharts().get(0);

//Add a WordArt watermark (shape) to the chart's plot area.
com.aspose.cells.Shape wordart = chart.getShapes().addTextEffectInChart(MsoPresetTextEffect.TEXT_EFFECT_2,
"CONFIDENTIAL", "Arial Black", 66, false, false, 1200, 500, 2000, 3000);

//Get the shape's fill format.
com.aspose.cells.MsoFillFormat wordArtFormat = wordart.getFillFormat();

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

//Get the line format and make it invisible.
com.aspose.cells.MsoLineFormat lineFormat = wordart.getLineFormat();
lineFormat.setVisible(false);

//Save the excel file.
workbook.save(filePath + ".out.xls", SaveFormat.EXCEL_97_TO_2003);
