开发人员常常需要完成的一个任务是动态地向幻灯片添加文本。本文展示了使用 VSTO 和 Aspose.Slides for Android via Java 动态添加文本的代码示例。
动态添加文本
这两种方法遵循以下步骤:
- 创建一个演示文稿。
- 添加一个空白幻灯片。
- 添加一个文本框。
- 设置一些文本。
- 写入演示文稿。
VSTO 代码示例
下面的代码片段创建了一个带有普通幻灯片和一串文本的演示文稿。

//Note: PowerPoint is a namespace which has been defined above like this | |
//using PowerPoint = Microsoft.Office.Interop.PowerPoint; | |
//Create a presentation | |
PowerPoint.Presentation pres = Globals.ThisAddIn.Application | |
.Presentations.Add(Microsoft.Office.Core.MsoTriState.msoFalse); | |
//Get the blank slide layout | |
PowerPoint.CustomLayout layout = pres.SlideMaster. | |
CustomLayouts[7]; | |
//Add a blank slide | |
PowerPoint.Slide sld = pres.Slides.AddSlide(1, layout); | |
//Add a text | |
PowerPoint.Shape shp = sld.Shapes.AddTextbox(Microsoft.Office.Core.MsoTextOrientation.msoTextOrientationHorizontal, 150, 100, 400, 100); | |
//Set a text | |
PowerPoint.TextRange txtRange = shp.TextFrame.TextRange; | |
txtRange.Text = "Text added dynamically"; | |
txtRange.Font.Name = "Arial"; | |
txtRange.Font.Bold = Microsoft.Office.Core.MsoTriState.msoTrue; | |
txtRange.Font.Size = 32; | |
//Write the output to disk | |
pres.SaveAs("c:\\outVSTO.ppt", | |
PowerPoint.PpSaveAsFileType.ppSaveAsPresentation, | |
Microsoft.Office.Core.MsoTriState.msoFalse); | |

//Create a presentation | |
Presentation pres = new Presentation(); | |
//Blank slide is added by default, when you create | |
//presentation from default constructor | |
//So, we don't need to add any blank slide | |
ISlide sld = pres.getSlides().get_Item(1); | |
//Add a textbox | |
//To add it, we will first add a rectangle | |
IShape shp = sld.getShapes().addAutoShape(ShapeType.Rectangle, 1200, 800, 3200, 370); | |
//Hide its line | |
shp.getLineFormat().setStyle(LineStyle.NotDefined); | |
//Then add a textframe inside it | |
ITextFrame tf = ((IAutoShape)shp).getTextFrame(); | |
//Set a text | |
tf.setText("Text added dynamically"); | |
IPortion port = tf.getParagraphs().get_Item(0).getPortions().get_Item(0); | |
port.getPortionFormat().setFontBold(NullableBool.True); | |
port.getPortionFormat().setFontHeight(32); | |
//Write the output to disk | |
pres.save("c:\\data\\outAsposeSlides.pptx",SaveFormat.Pptx); |
