使用Apache POI XSLF在指定位置的单张幻灯片中附加3张图像

我需要使用Apache POI XSLF在单张幻灯片中粘贴3张图片。 但是，我只能在幻灯片中添加一张图片。 此外，我找不到任何方法来指定图片的大小和方向。

试过以下代码

XMLSlideShow ppt = new XMLSlideShow(); XSLFSlide slide = ppt.createSlide(); XSLFGroupShape group1 = slide.createGroup(); byte buf[] = new byte[1024]; for (int i = 1; i <= 2; i++) { byte[] pictureData = IOUtils.toByteArray(new FileInputStream( "C:\\Users\\Ashok\\Pictures\\" + i + ".png")); int elementIndex = ppt.addPicture(pictureData, XSLFPictureData.PICTURE_TYPE_PNG); XSLFPictureShape picture = slide.createPicture(elementIndex); List allPictures = ppt.getAllPictures(); System.out.println(allPictures.size()); } FileOutputStream fos = new FileOutputStream("C:\\test2.pptx"); ppt.write(fos); fos.flush(); fos.close(); 

以上代码仅包含最后一张图片。

你需要将Anchor设置为你的照片

 for (int i = 1; i <= 2; i++) { byte[] pictureData = IOUtils.toByteArray(new FileInputStream( "C:\\Users\\Ashok\\Pictures\\" + i + ".png")); int elementIndex = ppt.addPicture(pictureData, XSLFPictureData.PICTURE_TYPE_PNG); XSLFPictureShape picture = slide.createPicture(elementIndex); // Set picture position and size picture.setAnchor(new Rectangle(positionX, positionY, width, height)); List allPictures = ppt.getAllPictures(); System.out.println(allPictures.size()); }
