如何创建 Hello World 演示文档

一个新的 Aspose.Slides for PHP via Java API 已经发布，现在这个单一产品支持从零开始生成 PowerPoint 文档以及编辑现有文档的能力。

对遗留代码的支持

为了使用与 Aspose.Slides for PHP via Java 早于 13.x 版本开发的遗留代码，您需要对代码进行一些小的修改，代码将像以前一样工作。之前在 Aspose.Slide 和 Aspose.Slides.Pptx 命名空间下的旧 Aspose.Slides for PHP via Java 中的所有类现在已合并到单一的 Aspose.Slides 命名空间中。请查看以下简单代码片段，了解如何在遗留 Aspose.Slides API 中创建 Hello World 演示文档，并按照描述迁移到新合并 API 的步骤进行操作。

遗留的 Aspose.Slides for PHP via 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 PHP via 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);
