java 替换 ppt 中的图片-ag凯发旗舰厅

本文介绍如何使用spire.presentation for java获取指定幻灯片中的图片形状，并用新图片进行填充。

import com.spire.presentation.*;
import com.spire.presentation.drawing.iimagedata;
import javax.imageio.imageio;
import java.awt.image.bufferedimage;
import java.io.fileinputstream;
public class replaceimage {
    public static void main(string[] args) throws exception {
        //创建presentation对象
        presentation presentation= new presentation();
        //加载powerpoint示例文档
        presentation.loadfromfile("c:\\users\\administrator\\desktop\\input.pptx");
        //添加图片到图片集合
        string imagepath = "c:\\users\\administrator\\desktop\\microsoft-powerpoint-logo.jpg";
        bufferedimage bufferedimage = imageio.read(new fileinputstream(imagepath));
        iimagedata image = presentation.getimages().append(bufferedimage);
        //获取第一张幻灯片上形状集合
        shapecollection shapes = presentation.getslides().get(0).getshapes();
        //遍历所有形状
        for (int i = 0; i < shapes.getcount(); i  ) {
            //判断形状是否是图片
            if (shapes.get(i) instanceof slidepicture) {
                //将图片形状用新图片填充
               ((slidepicture) shapes.get(i)).getpicturefill().getpicture().setembedimage(image);
            }
        }
        //保存文档
        presentation.savetofile("output/replaceimage.pptx", fileformat.pptx_2013);
    }
}
