创建一个 Diagram
Aspose.Diagram for Java 允许您从自己的应用程序中读取和创建 Microsoft Visio 图表,无需 Microsoft Office 自动化。创建新文档的第一步是创建一个 diagram。然后添加形状和连接器构建 diagram。使用默认构造函数Diagram类创建一个新的 diagram。

// 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(CreateDiagram.class); | |
// Create directory if it is not already present. | |
File file = new File(dataDir); | |
if (!file.exists()) | |
file.mkdir(); | |
// initialize a new Diagram | |
Diagram diagram = new Diagram(); | |
// save in the VSDX format | |
diagram.save(dataDir + "CreateDiagram_Out.vsdx", SaveFileFormat.VSDX); |
这个例子的工作原理如下:
- 创建 Diagram 类的对象。
- 页面中visio加水印
- 调用 Diagram 类对象的 Save 方法,并传递完整的文件路径和 DiagramSaveOptions 对象。
添加水印编程示例
下面的示例代码展示了如何在 Visio diagram 中添加水印。

// The path to the documents directory. | |
String dataDir = Utils.getDataDir(AddWatermarkToVisio.class); | |
// load diagram | |
Diagram diagram = new Diagram(dataDir + "Drawing1.vsdx"); | |
// get page by name | |
Page page = diagram.getPages().getPage("Page-1"); | |
double pinx = page.getPageSheet().getPageProps().getPageWidth().getValue() / 2; | |
double piny = page.getPageSheet().getPageProps().getPageHeight().getValue() / 2; | |
double width = page.getPageSheet().getPageProps().getPageWidth().getValue(); | |
double height =page.getPageSheet().getPageProps().getPageHeight().getValue(); | |
//Add watermark | |
Shape shape = page.addText(pinx, piny, width, height, "Test text","Calibri","#a5a5a5",0.25); | |
// save diagram | |
diagram.save(dataDir + "ApplyFontOnText_Out.vsdx", SaveFileFormat.VSDX); |
