How C # Adds a PPT background (solid background, gradient background, picture background)

Overview

When we create a PowerPoint document, the system's default slide is a blank background, and many times we need to customize the slide background to achieve beautiful document effects. The following example shows a way to set the background for a PowerPoint slide, consisting mainly of the following three sections:

• Add a solid color background
• Add a gradient background
• Add a picture as a tool for the background
• Free spire.presentation for. NET version 3.3 (Community edition)

Sample code (for reference)

Step 1: Add the following using directives

using Spire.Presentation;using Spire.Presentation.Drawing;using System.Drawing;

Step 2: Create a document

Presentation ppt = new Presentation();ppt.LoadFromFile("test.pptx");

Step 3: Add a solid color background

//设置文档的背景填充模式为纯色填充ppt.Slides[0].SlideBackground.Type = BackgroundType.Custom;ppt.Slides[0].SlideBackground.Fill.FillType = FillFormatType.Solid;ppt.Slides[0].SlideBackground.Fill.SolidColor.Color = Color.Pink;

Step 4: Add a gradient background color

//设置文档的背景填充模式为渐变色填充ppt.Slides[1].SlideBackground.Type = BackgroundType.Custom;ppt.Slides[1].SlideBackground.Fill.FillType = FillFormatType.Gradient;ppt.Slides[1].SlideBackground.Fill.Gradient.GradientStops.Append(0f, KnownColors.Yellow);ppt.Slides[1].SlideBackground.Fill.Gradient.GradientStops.Append(1f, KnownColors.Orange);

Step 5: Add a picture as a background

//设置幻灯片背景色为图片背景ppt.Slides[2].SlideBackground.Type = Spire.Presentation.Drawing.BackgroundType.Custom;ppt.Slides[2].SlideBackground.Fill.FillType = FillFormatType.Picture;ppt.Slides[2].SlideBackground.Fill.PictureFill.FillType = PictureFillType.Stretch;//加载图片作为幻灯片背景Image img = Image.FromFile("green.png");IImageData image = ppt.Images.Append(img);ppt.Slides[2].SlideBackground.Fill.PictureFill.Picture.EmbedImage = image;

Step 6: Save the file

ppt.SaveToFile("result.pptx", FileFormat.Pptx2010);System.Diagnostics.Process.Start("result.pptx");

After the code is finished, debug the Run program and generate the file as follows:

All code:

Using spire.presentation;using spire.presentation.drawing;using System.drawing;namespace AddBackground_PPT{class program {static void Main (string[] args) {//Instantiate presentation class, load PowerPoint document Prese            ntation ppt = new Presentation (); Ppt.            LoadFromFile ("Test.pptx"); Sets the background fill mode for the document to fill the PPT with a solid color. Slides[0].            Slidebackground.type = Backgroundtype.custom; Ppt. Slides[0].            SlideBackground.Fill.FillType = Fillformattype.solid; Ppt. Slides[0].            SlideBackground.Fill.SolidColor.Color = Color.pink; Sets the background fill mode for the document to fill the PPT with the gradient. SLIDES[1].            Slidebackground.type = Backgroundtype.custom; Ppt. SLIDES[1].            SlideBackground.Fill.FillType = fillformattype.gradient; Ppt. SLIDES[1].            SlideBackground.Fill.Gradient.GradientStops.Append (0f, Knowncolors.yellow); Ppt. SLIDES[1].            SlideBackground.Fill.Gradient.GradientStops.Append (1f, Knowncolors.orange); Sets the slide background color for the picture background ppt.SLIDES[2].            Slidebackground.type = Spire.Presentation.Drawing.BackgroundType.Custom; Ppt. SLIDES[2].            SlideBackground.Fill.FillType = fillformattype.picture; Ppt. SLIDES[2].            SlideBackground.Fill.PictureFill.FillType = Picturefilltype.stretch;            Load picture as slide background image img = image.fromfile ("Green.png"); Iimagedata image = ppt.            Images.append (IMG); Ppt. SLIDES[2].            SlideBackground.Fill.PictureFill.Picture.EmbedImage = image; Save and open the document PPT.            SaveToFile ("Result.pptx", fileformat.pptx2010);        System.Diagnostics.Process.Start ("Result.pptx"); }    }}
