如何创建 Hello World 演示文档

一个新的 Aspose.Slides for Java API 已经发布，现在这个单一产品支持从零开始生成 PowerPoint 文档和编辑现有文档的功能。

对旧代码的支持

为了使用用 Aspose.Slides for Java 13.x 之前版本开发的旧代码，您需要对代码进行一些小的更改，代码将按照以前的方式工作。之前在旧的 Aspose.Slides for Java 中存在的所有类现在都已合并到单一的 Aspose.Slides 命名空间下。请查看以下简单代码片段，了解如何在旧的 Aspose.Slides API 中创建 Hello World 演示文档，并遵循描述如何迁移到新合并 API 的步骤。

旧的 Aspose.Slides for Java 方法

//Instantiate a Presentation object that represents a PPT file
    Presentation pres = new Presentation();
    //Create a License object
    License license = new License();
    //Set the license of Aspose.Slides for Java to avoid the evaluation limitations
    license.setLicense("Aspose.Slides.lic");


    //Adding an empty slide to the presentation and getting the reference of
    //that empty slide
    Slide slide = pres.addEmptySlide();

    //Adding a rectangle (X=2400, Y=1800, Width=1000 & Height=500) to the slide
    com.aspose.slides.Rectangle rect = slide.getShapes().addRectangle(2400, 1800, 1000, 500);
    //Hiding the lines of rectangle
    rect.getLineFormat().setShowLines(false);
    //Adding a text frame to the rectangle with "Hello World" as a default text
    rect.addTextFrame("Hello World");
    //Removing the first slide of the presentation which is always added by
    //Aspose.Slides for Java by default while creating the presentation
    pres.getSlides().removeAt(0);


    //Writing the presentation as a PPT file
    pres.write("C:\\hello.ppt");
        

新的 Aspose.Slides for Java 14.x.x 方法

// The path to the documents directory.
      	String dataDir = Utils.getDataDir(CreateAPresentation.class);
      
// Instantiate Presentation
Presentation pres = new Presentation();

// Get the first slide
ISlide sld = (ISlide) pres.getSlides().get_Item(0);

// Add an AutoShape of Rectangle type
IAutoShape ashp = sld.getShapes().addAutoShape(ShapeType.Rectangle, 150, 75, 150, 50);

// Add ITextFrame to the Rectangle
ashp.addTextFrame("Hello World");

// Change the text color to Black (which is White by default)
ashp.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getPortionFormat().getFillFormat()
		.setFillType(FillType.Solid);
ashp.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getPortionFormat().getFillFormat()
		.getSolidFillColor().setColor(java.awt.Color.BLACK);

// Change the line color of the rectangle to White
ashp.getShapeStyle().getLineColor().setColor(java.awt.Color.WHITE);

// Remove any fill formatting in the shape
ashp.getFillFormat().setFillType(FillType.NoFill);

// Save the presentation to disk
pres.save(dataDir + "HelloWorld.pptx", com.aspose.slides.SaveFormat.Pptx);
