Implementation Guide

Applying Custom Tilt Effect during Document Rasterization

This feature allows you to add an artistic tilt effect, making your documents more visually engaging. Here’s how to implement it:

Overview of Feature

Apply a custom tilt effect when rasterizing a document using GroupDocs.Redaction Java by configuring advanced options.

Step-by-Step Implementation

Initialize Redactor and Save Options
import com.groupdocs.redaction.options.AdvancedRasterizationOptions;
import java.util.HashMap;

Redactor redactor = new Redactor("YOUR_DOCUMENT_DIRECTORY/MULTIPAGE_SAMPLE_DOCX");
SaveOptions saveOptions = new SaveOptions();
Configure Tilt Effect Settings

Enable rasterization and set the custom tilt effect parameters:

saveOptions.getRasterization().setEnabled(true);
HashMap<String, String> tiltSettings = new HashMap<>();
tiltSettings.put("minAngle", "15"); // Set the minimum angle for the tilt effect
	tiltSettings.put("maxAngle", "30"); // Set the maximum angle for the tilt effect

saveOptions.getRasterization().addAdvancedOption(
    AdvancedRasterizationOptions.Tilt, 
    tiltSettings
);
Save Document with Tilt Effect

Apply these settings and save the document:

redactor.save("OUTPUT_DIRECTORY/MULTIPAGE_SAMPLE_DOCX_scan", saveOptions);

Explanation of Parameters

  • minAngle: Specifies the minimum tilt angle.
  • maxAngle: Defines the maximum tilt angle.

These parameters allow you to control how pronounced the tilt effect will be in your document.

Troubleshooting Tips
  • Ensure all paths are correctly specified and accessible by your application.
  • Double-check the GroupDocs.Redaction library version for compatibility with your project settings.

Practical Applications

Applying a custom tilt effect is beneficial in various scenarios:

  1. Creative Document Presentation: Enhance presentations or reports with unique visual effects.
  2. Marketing Materials: Make brochures and flyers more engaging by adding dynamic visuals.
  3. Archival Documents: Add artistic flair to historical documents for digital archives.

Performance Considerations

Optimizing Performance

When working with large documents, consider the following tips:

  • Efficient Memory Management: Ensure your Java environment has sufficient memory allocated.
  • Optimize I/O Operations: Minimize read/write operations by processing in batches if possible.

Best Practices for Java Memory Management

Utilize garbage collection effectively and avoid unnecessary object creation to manage resources efficiently.

Conclusion

In this tutorial, you’ve learned how to implement a custom tilt effect using GroupDocs.Redaction Java. By following the steps outlined above, you can enhance your documents with unique visual effects that captivate your audience.
