Basic Initialization and Setup

To set up GroupDocs.Signature, initialize the Signature object with your document’s path:

String filePath = "YOUR_DOCUMENT_DIRECTORY"; // Replace with actual file path
Signature signature = new Signature(filePath);

Implementation Guide

Let’s break down the implementation into key features.

Feature: Radial Gradient Brush Signature

This feature allows you to sign a document using text styled with a radial gradient brush, giving it a modern and professional look.

1. Initialize Signature Object

Start by creating an instance of the Signature class with your document path:

String filePath = "YOUR_DOCUMENT_DIRECTORY"; // Replace with actual file path
Signature signature = new Signature(filePath);

2. Configure Text Sign Options

Set up the text sign options, specifying the text to be signed and its appearance:

TextSignOptions options = new TextSignOptions("John Smith");

3. Setup Background with Radial Gradient Brush

Create a background with a radial gradient brush for enhanced visual appeal:

Background background = new Background();
background.setColor(Color.GREEN);  // Main color of the brush
background.setTransparency(0.5f);   // Transparency level
background.setBrush(new RadialGradientBrush(Color.GREEN, Color.WHITE)); // Gradient effect
options.setBackground(background);

4. Configure Signature Position and Size

Define the size and alignment of your signature on the document:

options.setWidth(100);  // Width of the text box
options.setHeight(80);   // Height of the text box
options.setVerticalAlignment(VerticalAlignment.Center); // Vertical centering
c.options.setHorizontalAlignment(HorizontalAlignment.Center); // Horizontal centering

5. Add Padding Around Signature

Add padding to ensure your signature has sufficient space around it:

Padding padding = new Padding();
padding.setTop(20);
padding.setRight(20);
options.setMargin(padding);

6. Choose Signature Implementation Method

Select the method for rendering the signature on the page:

options.setSignatureImplementation(TextSignatureImplementation.Image); // Image-based rendering

7. Sign and Save the Document

Finally, sign your document and save it to a specified output path:

String outputFilePath = "YOUR_OUTPUT_DIRECTORY/\SignedRadialGradientBrush.pdf"; // Replace with desired output path
signature.sign(outputFilePath, options);

Feature: Background Configuration

This feature focuses on configuring the background for text signatures using transparency and radial gradients.

Create and Configure Background Object

Create a Background object and set its properties:

Background background = new Background();
background.setColor(Color.GREEN);  // Main color of the brush
background.setTransparency(0.5f);   // Transparency level
background.setBrush(new RadialGradientBrush(Color.GREEN, Color.WHITE)); // Gradient effect

Feature: Text Signature Options Configuration

This feature involves configuring text signature options such as size, alignment, and padding.

Configure Signature Appearance

Set up the TextSignOptions to define how your text signature will appear:

TextSignOptions options = new TextSignOptions("John Smith");

// Define width, height, and alignment
options.setWidth(100);
options.setHeight(80);
options.setVerticalAlignment(VerticalAlignment.Center);
options.setHorizontalAlignment(HorizontalAlignment.Center);

// Set padding for the signature
Padding padding = new Padding();
padding.setTop(20);
padding.setRight(20);
options.setMargin(padding);

// Apply the configured background to the text signature
options.setBackground(background);

Practical Applications

Here are some real-world use cases for implementing radial gradient brush signatures:

  1. Legal Documents: Enhance the presentation of contracts and agreements.
  2. Financial Reports: Add a professional touch to financial statements.
  3. Marketing Collateral: Make promotional materials stand out with unique signatures.
