Set a solid background color

import com.spire.presentation.*;
import com.spire.presentation.drawing.*;

import java.awt.*;

public class PPTbackground {

    public static void main(String[] args) throws Exception {

        //加载PowerPoint文档
        Presentation ppt = new Presentation();
        ppt.loadFromFile("Sample.pptx");

        //获取幻灯片的数量
        int slideCount = ppt.getSlides().getCount();

        ISlide slide = null;

        //遍历幻灯片，为每张幻灯片设置纯色背景色
        for(int i = 0; i < slideCount;i++) {
            slide = ppt.getSlides().get(i);
            slide.getSlideBackground().setType(BackgroundType.CUSTOM);

            //设置纯色背景填充
            slide.getSlideBackground().getFill().setFillType(FillFormatType.SOLID);
            slide.getSlideBackground().getFill().getSolidColor().setColor(Color.lightGray);
        }
        //保存结果文档
        ppt.saveToFile("纯色背景.pptx", FileFormat.PPTX_2010);
    }
}

        ISlide slide = null;

        //遍历幻灯片，为每张幻灯片设置渐变背景色
        for(int i = 0; i < slideCount;i++) {
            slide = ppt.getSlides().get(i);
            slide.getSlideBackground().setType(BackgroundType.CUSTOM);

            //设置渐变背景色填充
        slide.getSlideBackground().getFill().setFillType(FillFormatType.GRADIENT);
        slide.getSlideBackground().getFill().getGradient().getGradientStops().append(0, Color.WHITE);
        slide.getSlideBackground().getFill().getGradient().getGradientStops().append(1, Color.LIGHT_GRAY);

        }
        //保存结果文档
        ppt.saveToFile("渐变色背景.pptx", FileFormat.PPTX_2010);
