Example 1 To the whole Word Add background color to the document

1） add to Pure color Background color

import com.spire.doc.*;
import com.spire.doc.documents.BackgroundType;
import java.awt.*;
public class SolidBackgroundColor {
public static void main(String[] args) {
// load Word Sample document
Document document= new Document("C:UsersTest1DesktopSample.docx");
// Add background color and set color type
document.getBackground().setType(BackgroundType.Color);
document.getBackground().setColor(Color.lightGray);
// Save the result file
document.saveToFile("output/AddSolidColor.docx", FileFormat.Docx);
}
}

2） add to gradient Background color

import com.spire.doc.*;
import com.spire.doc.documents.BackgroundType;
import com.spire.doc.documents.GradientShadingStyle;
import com.spire.doc.documents.GradientShadingVariant;
import java.awt.*;
public class GradientBackgroundColor {
public static void main(String[] args) {
// load Word Sample document
Document document= new Document("C:UsersTest1DesktopSample.docx");
// Add background color and set color type
document.getBackground().setType(BackgroundType.Gradient);
document.getBackground().getGradient().setColor1(Color.white);
document.getBackground().getGradient().setColor2(Color.cyan);
document.getBackground().getGradient().setShadingVariant(GradientShadingVariant.Shading_Down);
document.getBackground().getGradient().setShadingStyle(GradientShadingStyle.Horizontal);
// Save the result file
document.saveToFile("output/AddGradientColor.docx", FileFormat.Docx_2013);
}
}

Example 2 Adds a background color to a specified paragraph or text in a document

import com.spire.doc.*;
import com.spire.doc.documents.*;
import com.spire.doc.fields.*;
import java.awt.*;
public class SetParagraphShading {
public static void main(String[] args) {
// load Word Sample document
Document document = new Document();
document.loadFromFile("C:UsersTest1DesktopSample.docx");
// Get the specified paragraph in the document
Paragraph paragaph = document.getSections().get(0).getParagraphs().get(3);
// Adds a background color to the specified paragraph
paragaph.getFormat().setBackColor(Color.yellow);
// Get the specified text in the document
paragaph = document.getSections().get(0).getParagraphs().get(1);
TextSelection selection = paragaph.find(" Christmas ", true, false);
// Adds a background color to the specified text
TextRange range = selection.getAsOneRange();
range.getCharacterFormat().setTextBackgroundColor(Color.pink);
// Save the result file
document.saveToFile("output/AddParagraphShading.docx", FileFormat.Docx_2013);
}
}
