Implementation Guide

In this section, we’ll dive into how to implement the search functionality for text-formatted watermarks using GroupDocs.Watermark.

Setting Up Text Formatting Search Criteria

Overview

To find watermarks with specific formatting, define your criteria using TextFormattingSearchCriteria.

Step 1: Define Foreground Color Range

Start by specifying the color range for foreground colors:

ColorRange foregroundColorRange = new ColorRange();
foregroundColorRange.setMinHue(-5);  // Minimum hue value
foregroundColorRange.setMaxHue(10);   // Maximum hue value
foregroundColorRange.setMinBrightness(0.01f);
foregroundColorRange.setMaxBrightness(0.99f);
criteria.setForegroundColorRange(foregroundColorRange);

Explanation: This configuration searches for watermarks with foreground colors within the specified hue and brightness range.

Step 2: Define Background Color Range

Set background color criteria:

ColorRange backgroundColorRange = new ColorRange();
backgroundColorRange.setEmpty(true);  // No specific background color range
criteria.setBackgroundColorRange(backgroundColorRange);

Explanation: By setting setEmpty(true), we’re indicating no specific background color range, allowing for broader searches.

Step 3: Additional Text Formatting

Configure other text attributes:

criteria.setFontName("Arial");          // Font name to search for
criteria.setMinFontSize(19);            // Minimum font size
criteria.setMaxFontSize(42);            // Maximum font size
criteria.setFontBold(true);             // Search only bold fonts

Explanation: This narrows the search to watermarks that use Arial, are bold, and fall within a specified font size range.

Execute the search with your criteria:

PossibleWatermarkCollection watermarks = watermarker.search(criteria);

Troubleshooting Tips

  • Common Issues: Ensure your document path is correct. Verify that the formatting attributes match those in your document.
  • Debugging: Use logging to track which parameters are being applied and adjust as necessary.

Practical Applications

  1. Document Verification: Quickly verify if a document contains specific watermarks before processing or sharing.
  2. Copyright Protection: Ensure only authorized versions of documents circulate by checking for proprietary watermarks.
  3. Collaboration Tools: Integrate watermark searching into collaboration platforms to track document origins and edits.

Performance Considerations

  • Optimize Searches: Limit search criteria to essential parameters to enhance performance.

  • Memory Management: Efficiently manage resources by closing the Watermarker instance after use:

    watermarker.close();

  • Best Practices: Regularly update your GroupDocs library to leverage performance improvements and bug fixes.
