GroupDocs.Comparison provides the compare options collection to set up the appropriate comparison speed and quality.
To compare two documents with custom change style settings, follow these steps:
- Instantiate the Comparer object. Specify the source document path or stream.
- Call the add() method. Specify the target document path or stream.
- Instantiate the CompareOptions object. Specify the appropriate parameters.
- Call the compare() method. Specify the CompareOptions object.
The following code snippets show how to compare documents with specific options:
import com.groupdocs.comparison.Comparer;
import com.groupdocs.comparison.options.CompareOptions;
import com.groupdocs.comparison.options.style.StyleSettings;
import java.awt.*;
import java.nio.file.Path;
// ...
try (Comparer comparer = new Comparer("source.docx")) {
comparer.add("target.docx");
CompareOptions compareOptions = new CompareOptions();
final StyleSettings insertedStyleSettings = new StyleSettings();
insertedStyleSettings.setHighlightColor(Color.RED);
insertedStyleSettings.setFontColor(Color.GREEN);
insertedStyleSettings.setUnderline(true);
insertedStyleSettings.setBold(true);
insertedStyleSettings.setStrikethrough(true);
insertedStyleSettings.setItalic(true);
compareOptions.setInsertedItemStyle(insertedStyleSettings);
final StyleSettings deletedStyleSettings = new StyleSettings();
deletedStyleSettings.setHighlightColor(Color.PINK);
deletedStyleSettings.setFontColor(Color.CYAN);
deletedStyleSettings.setUnderline(true);
deletedStyleSettings.setBold(true);
deletedStyleSettings.setStrikethrough(true);
deletedStyleSettings.setItalic(true);
compareOptions.setDeletedItemStyle(deletedStyleSettings);
final StyleSettings changedStyleSettings = new StyleSettings();
changedStyleSettings.setHighlightColor(Color.LIGHT_GRAY);
changedStyleSettings.setFontColor(Color.GRAY);
changedStyleSettings.setUnderline(true);
changedStyleSettings.setBold(true);
changedStyleSettings.setStrikethrough(true);
changedStyleSettings.setItalic(true);
compareOptions.setChangedItemStyle(changedStyleSettings);
final Path resultPath = comparer.compare("result.docx", compareOptions);
}
The result is as follows:
import com.groupdocs.comparison.Comparer;
import com.groupdocs.comparison.options.CompareOptions;
import com.groupdocs.comparison.options.style.StyleSettings;
import java.awt.*;
import java.nio.file.Path;
import java.io.FileInputStream;
import java.io.InputStream;
// ...
try (Comparer comparer = new Comparer(sourceInputStream)) {
comparer.add(targetInputStream);
CompareOptions compareOptions = new CompareOptions();
final StyleSettings insertedStyleSettings = new StyleSettings();
insertedStyleSettings.setHighlightColor(Color.RED);
insertedStyleSettings.setFontColor(Color.GREEN);
insertedStyleSettings.setUnderline(true);
insertedStyleSettings.setBold(true);
insertedStyleSettings.setStrikethrough(true);
insertedStyleSettings.setItalic(true);
compareOptions.setInsertedItemStyle(insertedStyleSettings);
final StyleSettings deletedStyleSettings = new StyleSettings();
deletedStyleSettings.setHighlightColor(Color.PINK);
deletedStyleSettings.setFontColor(Color.CYAN);
deletedStyleSettings.setUnderline(true);
deletedStyleSettings.setBold(true);
deletedStyleSettings.setStrikethrough(true);
deletedStyleSettings.setItalic(true);
compareOptions.setDeletedItemStyle(deletedStyleSettings);
final StyleSettings changedStyleSettings = new StyleSettings();
changedStyleSettings.setHighlightColor(Color.LIGHT_GRAY);
changedStyleSettings.setFontColor(Color.GRAY);
changedStyleSettings.setUnderline(true);
changedStyleSettings.setBold(true);
changedStyleSettings.setStrikethrough(true);
changedStyleSettings.setItalic(true);
compareOptions.setChangedItemStyle(changedStyleSettings);
final Path resultPath = comparer.compare(resultInputStream, compareOptions);
}
