java 给 powerpoint 幻灯片添加背景颜色和背景图片-人生就是博尊龙凯时

该示例将详细讲述如何使用spire.presentation for java在java应用程序中为幻灯片设置纯色背景颜色，渐变背景颜色以及添加背景图片。

设置背景图片

import com.spire.presentation.*;
import com.spire.presentation.drawing.*;
public class pptbackground {
    public static void main(string[] args) throws exception {
        string inputfile = "sample.pptx";
        string imagefile = "1.png";
        string outputfile = "output/setbackgroundcolor.pptx";
        presentation ppt = new presentation();
        ppt.loadfromfile(inputfile);
        ppt.getslides().get(0).getslidebackground().settype(backgroundtype.custom);
//设置文档的背景填充模式为图片填充
        ppt.getslides().get(0).getslidebackground().getfill().setfilltype(fillformattype.picture);
        ppt.getslides().get(0).getslidebackground().getfill().getpicturefill().setalignment(rectanglealignment.none);
        ppt.getslides().get(0).getslidebackground().getfill().getpicturefill().setfilltype(picturefilltype.stretch);
        ppt.getslides().get(0).getslidebackground().getfill().getpicturefill().getpicture().set).getabsolutepath());
        ppt.savetofile(outputfile, fileformat.pptx_2010);
        ppt.dispose();
    }
}

设置纯色背景颜色

import com.spire.presentation.*;
import com.spire.presentation.drawing.*;
public class pptbackground {
    public static void main(string[] args) throws exception {
        string inputfile = "sample.pptx";
        string outputfile = "output/setbackgroundcolor.pptx";
        presentation ppt = new presentation();
        ppt.loadfromfile(inputfile);
        ppt.getslides().get(0).getslidebackground().settype(backgroundtype.custom);
//设置文档的背景填充模式为纯色填充，设置颜色
        ppt.getslides().get(0).getslidebackground().getfill().setfilltype(fillformattype.solid);
        ppt.getslides().get(0).getslidebackground().getfill().getsolidcolor().setcolor(java.awt.color.light_gray);
        ppt.savetofile(outputfile, fileformat.pptx_2010);
        ppt.dispose();
    }
}

设置渐变色背景颜色

import com.spire.presentation.*;
import com.spire.presentation.drawing.*;
import java.awt.*;
public class pptbackground {
    public static void main(string[] args) throws exception {
        string inputfile = "sample.pptx";
        string outputfile = "output/setgradientcolor.pptx";
        presentation ppt = new presentation();
        ppt.loadfromfile(inputfile);
        ppt.getslides().get(0).getslidebackground().settype(backgroundtype.custom);
//设置文档的背景填充模式为渐变色填充，设置颜色
        ppt.getslides().get(0).getslidebackground().getfill().setfilltype(fillformattype.gradient);
        ppt.getslides().get(0).getslidebackground().getfill().getgradient().getgradientstops().append(0, color.white);
        ppt.getslides().get(0).getslidebackground().getfill().getgradient().getgradientstops().append(1,color.green);
        ppt.savetofile(outputfile, fileformat.pptx_2010);
        ppt.dispose();
    }
}
