Adding a background color to a Word document is quite simple. You just need to set the background type as color and then choose a color as the background. The detailed steps are as follows.
- Create a Document instance.
- Load a sample Word document using Document.LoadFromFile() method.
- Set the background type as color using Document.Background.Type property.
- Set a background color for the document using Document.Background.Color property.
- Save the result document using Document.SaveToFile() method.
- C#
- VB.NET
using Spire.Doc;
using System.Drawing;
using Spire.Doc.Documents;
namespace ConvertWordToPng
{
class Program
{
static void Main(string[] args)
{
//Create a Document instance
Document document = new Document();
//Load a sample Word document
document.LoadFromFile("Test.docx");
//Set the background type as color
document.Background.Type = BackgroundType.Color;
//Set the background color
document.Background.Color = Color.AliceBlue;
//Save the document
document.SaveToFile("PureColorBackground.docx", FileFormat.Docx);
}
}
}
Add a Gradient Background to a Word Document
Adding gradient background requires more steps. You need to set the background type as gradient, choose two colors, and then set shading variant and style. The detailed steps are as follows.
- Create a Document instance.
- Load a sample Word document using Document.LoadFromFile() method.
- Set the background type as gradient using Document.Background.Type property.
- Get the background gradient using Document.Background.Gradient property.
- Select two colors using BackgroundGradient.Color1 and BackgroundGradient.Color2 properties.
- Set shading variant and style for the gradient using BackgroundGradient.ShadingVariant and BackgroundGradient. ShadingStyle properties.
- Save the result document using Document.SaveToFile() method.
- C#
- VB.NET
using Spire.Doc;
using System.Drawing;
using Spire.Doc.Documents;
namespace ConvertWordToPng
{
class Program
{
static void Main(string[] args)
{
//Create a Document instance
Document document = new Document();
//Load a sample Word document
document.LoadFromFile("Test.docx");
//Set the background type as gradient
document.Background.Type = BackgroundType.Gradient;
//Get the background gradient
BackgroundGradient gradient = document.Background.Gradient;
//Select two colors
gradient.Color1 = Color.White;
gradient.Color2 = Color.LightBlue;
//Set shading variant and style for the gradient
gradient.ShadingVariant = GradientShadingVariant.ShadingDown;
gradient.ShadingStyle = GradientShadingStyle.Horizontal;
//Save the document
document.SaveToFile("AddGradientBackground.docx", FileFormat.Docx);
}
}
}

{
{
//Create a Document instance
Document document = new Document();
//Load a sample Word document
document.LoadFromFile("Test.docx");
//Set the background type as picture
document.Background.Type = BackgroundType.Picture;
//Set background picture
document.Background.Picture = Image.FromFile("background.jpg");

RTF is a document language used for encoding formatted text and graphics for easy transfer between applications. This article presents how to insert a piece of RTF encoded string to Word document using Spire.Doc.
Step 1: Initialize an instance of Document class, add a section to it.
Document doc = new Document(); Section section = doc.
Step 2: Add a paragraph to the section.
Paragraph para = section.AddParagraph();
Step 3: Declare a String variable to store the RTF string.
String rtfString = @"{\rtf1\ansi\deff0 {\fonttbl {\f0 hakuyoxingshu7000;}}\f0\fs28 Hello, World}";
Step 4: Append RTF string to paragraph.
para.AppendRTF(rtfString);
Step 5: Save the file.
doc.SaveToFile("Output.docx");
Output:
