Using Styles and Themes in Aspose.Words for Java

Introduction to Using Styles and Themes in Aspose.Words for Java

In this guide, we will explore how to work with styles and themes in Aspose.Words for Java to enhance the formatting and appearance of your documents. We will cover topics such as retrieving styles, copying styles, managing themes, and inserting style separators. Let’s get started!

Retrieving Styles

To retrieve styles from a document, you can use the following Java code snippet:

Document doc = new Document();
String styleName = "";
// Get styles collection from the document.
StyleCollection styles = doc.getStyles();
for (Style style : styles)
{
    if ("".equals(styleName))
    {
        styleName = style.getName();
        System.out.println(styleName);
    }
    else
    {
        styleName = styleName + ", " + style.getName();
        System.out.println(styleName);
    }
}

This code fetches the styles defined in the document and prints their names.

Copying Styles

To copy styles from one document to another, you can use the copyStylesFromTemplate method as shown below:

@Test
public void copyStyles() throws Exception
{
    Document doc = new Document();
    Document target = new Document("Your Directory Path" + "Rendering.docx");
    target.copyStylesFromTemplate(doc);
    doc.save("Your Directory Path" + "WorkingWithStylesAndThemes.CopyStyles.docx");
}

This code copies styles from a template document to the current document.

Managing Themes

Themes are essential for defining the overall look of your document. You can retrieve and set theme properties as demonstrated in the following code:

@Test
public void getThemeProperties() throws Exception
{
    Document doc = new Document();
    Theme theme = doc.getTheme();
    System.out.println(theme.getMajorFonts().getLatin());
    System.out.println(theme.getMinorFonts().getEastAsian());
    System.out.println(theme.getColors().getAccent1());
}

@Test
public void setThemeProperties() throws Exception
{
    Document doc = new Document();
    Theme theme = doc.getTheme();
    theme.getMinorFonts().setLatin("Times New Roman");
    theme.getColors().setHyperlink(Color.ORANGE);
}

These snippets demonstrate how to retrieve and modify theme properties, such as fonts and colors.

Inserting Style Separators

Style separators are useful for applying different styles within a single paragraph. Here’s an example of how to insert style separators:

@Test
public void insertStyleSeparator() throws Exception
{
    Document doc = new Document();
    DocumentBuilder builder = new DocumentBuilder(doc);
    Style paraStyle = builder.getDocument().getStyles().add(StyleType.PARAGRAPH, "MyParaStyle");
    paraStyle.getFont().setBold(false);
    paraStyle.getFont().setSize(8.0);
    paraStyle.getFont().setName("Arial");
    // Append text with "Heading 1" style.
    builder.getParagraphFormat().setStyleIdentifier(StyleIdentifier.HEADING_1);
    builder.write("Heading 1");
    builder.insertStyleSeparator();
    // Append text with another style.
    builder.getParagraphFormat().setStyleName(paraStyle.getName());
    builder.write("This is text with some other formatting ");
    doc.save("Your Directory Path" + "WorkingWithStylesAndThemes.InsertStyleSeparator.docx");
}

In this code, we create a custom paragraph style and insert a style separator to switch styles within the same paragraph.
