新演示文稿

如下代碼建立一個新的.pptx幻燈片,並向其添加一個空白幻燈片:

//建立一個新的空幻燈片
XMLSlideShow ppt = new XMLSlideShow();

//添加第一張幻燈片
XSLFSlide blankSlide = ppt.createSlide（）;

閱讀現有演示文稿並附加幻燈片

XMLSlideShow ppt = new XMLSlideShow（new FileInputStream（"slideshow.pptx"））;

//附加一個新的幻燈片到最後
XSLFSlide blankSlide = ppt.createSlide（）;

從預約義的幻燈片佈局建立新的幻燈片

XMLSlideShow ppt = new XMLSlideShow（new FileInputStream（"slideshow.pptx"））;

//首先看看什麼幻燈片佈局可用:
System.out.println（"可用幻燈片佈局:"）;
for（XSLFSlideMaster master:ppt.getSlideMasters（））{
    for（XSLFSlideLayout layout:master.getSlideLayouts（））{
        的System.out.println（layout.getType（））;
    }
}

//空白幻燈片
XSLFSlide blankSlide = ppt.createSlide（）;

//能夠有多個主器件引用多個佈局
//爲了演示,咱們使用第一個（默認）幻燈片母版
XSLFSlideMaster defaultMaster = ppt.getSlideMasters（）.get（0）;

//標題幻燈片
XSLFSlideLayout titleLayout = defaultMaster.getLayout（SlideLayout.TITLE）;
//填寫佔位符
XSLFSlide slide1 = ppt.createSlide（titleLayout）;
XSLFTextShape title1 = slide1.getPlaceholder（0）;
title1.setText（"First Title"）;

//標題和內容
XSLFSlideLayout titleBodyLayout = defaultMaster.getLayout（SlideLayout.TITLE_AND_CONTENT）;
XSLFSlide slide2 = ppt.createSlide（titleBodyLayout）;

XSLFTextShape title2 = slide2.getPlaceholder（0）;
title2.setText（"Second Title"）;

XSLFTextShape body2 = slide2.getPlaceholder（1）;
body2.clearText（）; //取消設置任何現有文本
body2.addNewTextParagraph（）.addNewTextRun（）.setText（"First paragraph"）;
body2.addNewTextParagraph（）.addNewTextRun（）.setText（"Second paragraph"）;
body2.addNewTextParagraph（）.addNewTextRun（）.setText（"Third paragraph"）;

刪除幻燈片

XMLSlideShow ppt = new XMLSlideShow（new FileInputStream（"slideshow.pptx"））;

ppt.removeSlide（0）; //要刪除的幻燈片的基於0的索引

從新排列幻燈片

XMLSlideShow ppt = new XMLSlideShow（new FileInputStream（"slideshow.pptx"））;
列表<XSLFSlide> slides = ppt.getSlides（）;

XSLFSlide thirdSlide = slides.get（2）;
ppt.setSlideOrder（thirdSlide,0）; //將第三張幻燈片移動到開頭

如何檢索或更改幻燈片大小

XMLSlideShow ppt = new XMLSlideShow();
//檢索頁面大小。座標表示爲點數（72 dpi）
java.awt.Dimension pgsize = ppt.getPageSize（）;
int pgx = pgsize.width; //滑動寬度的點數
int pgy = pgsize.height; //滑動高度的點數

//設置新頁面大小
ppt.setPageSize（new java.awt.Dimension（1024,768））;

如何讀取特定幻燈片中包含的形狀

如下代碼演示瞭如何迭代每一個幻燈片的形狀。

The following code demonstrates how to iterate over shapes for each slide.

XMLSlideShow ppt = new XMLSlideShow(new FileInputStream("slideshow.pptx"));
// get slides
for (XSLFSlide slide : ppt.getSlides()) {
    for (XSLFShape sh : slide.getShapes()) {
        // name of the shape
        String name = sh.getShapeName();

        // shapes's anchor which defines the position of this shape in the slide
        if (sh instanceof PlaceableShape) {
            java.awt.geom.Rectangle2D anchor = ((PlaceableShape)sh).getAnchor();
        }

        if (sh instanceof XSLFConnectorShape) {
            XSLFConnectorShape line = (XSLFConnectorShape) sh;
            // work with Line
        } else if (sh instanceof XSLFTextShape) {
            XSLFTextShape shape = (XSLFTextShape) sh;
            // work with a shape that can hold text
        } else if (sh instanceof XSLFPictureShape) {
            XSLFPictureShape shape = (XSLFPictureShape) sh;
            // work with Picture
        }
    }
}

將圖片添加到幻燈片

XMLSlideShow ppt = new XMLSlideShow();
XSLFSlide slide = ppt.createSlide();

byte[] pictureData = IOUtils.toByteArray(new FileInputStream("image.png"));

XSLFPictureData pd = ppt.addPicture(pictureData, PictureData.PictureType.PNG);
XSLFPictureShape pic = slide.createPicture(pd);

閱讀演示文稿中包含的圖片

XMLSlideShow ppt = new XMLSlideShow(new FileInputStream("slideshow.pptx"));
    for(XSLFPictureData data : ppt.getAllPictures()){
        byte[] bytes = data.getData();
        String fileName = data.getFileName();
        
    }

基本文本格式

XMLSlideShow ppt = new XMLSlideShow();
XSLFSlide slide = ppt.createSlide();

XSLFTextBox shape = slide.createTextBox();
XSLFTextParagraph p = shape.addNewTextParagraph();

XSLFTextRun r1 = p.addNewTextRun();
r1.setText("The");
r1.setFontColor(Color.blue);
r1.setFontSize(24.);

XSLFTextRun r2 = p.addNewTextRun();
r2.setText(" quick");
r2.setFontColor(Color.red);
r2.setBold(true);

XSLFTextRun r3 = p.addNewTextRun();
r3.setText(" brown");
r3.setFontSize(12.);
r3.setItalic(true);
r3.setStrikethrough(true);

XSLFTextRun r4 = p.addNewTextRun();
r4.setText(" fox");
r4.setUnderline(true);

如何建立超連接

XMLSlideShow ppt = new XMLSlideShow();
XSLFSlide slide = ppt.createSlide();

// assign a hyperlink to a text run
XSLFTextBox shape = slide.createTextBox();
XSLFTextRun r = shape.addNewTextParagraph().addNewTextRun();
r.setText("Apache POI");
XSLFHyperlink link = r.createHyperlink();
link.setAddress("http://poi.apache.org");

PPTX2PNG是將.pptx幻燈片的每一個幻燈片轉換爲PNG圖像的應用程序

• 用法:PPTX2PNG [選項]

• 選項:
  -scale 比例因子（默認值爲1.0）
  -slide 1的幻燈片的索引。默認是渲染全部幻燈片。

• 怎麼運行的:
  XSLFSlide對象實現了一個繪製（Graphics2D圖形）方法,它將幻燈片中的全部形狀遞歸地繪製到提供的圖形畫布中:

  slide.draw（graphics）;

其中圖形是實現java.awt.Graphics2D的類。在PPTX2PNG中,圖形畫布派生自java.awt.image.BufferedImage,即目標是內存中的圖像,但在通常狀況下,您能夠傳遞任何兼容的java.awt.Graphics2D實現。該 PPTX2SVG 示例演示瞭如何使用Apache蠟染到幻燈片轉換成.PPTX SVG格式。

合併多個演示文稿

XMLSlideShow ppt = new XMLSlideShow();
String[] inputs = {"presentations1.pptx", "presentation2.pptx"};
for(String arg : inputs){
    FileInputStream is = new FileInputStream(arg);
    XMLSlideShow src = new XMLSlideShow(is);
    is.close();

    for(XSLFSlide srcSlide : src.getSlides()){
        ppt.createSlide().importContent(srcSlide);
    }
}

FileOutputStream out = new FileOutputStream("merged.pptx");
ppt.write(out);
out.close();
