Basic Initialization

Initialize the Watermarker class as shown below:

import com.groupdocs.watermark.options.EmailLoadOptions;

EmailLoadOptions loadOptions = new EmailLoadOptions();
Watermarker watermarker = new Watermarker("input_email.msg", loadOptions);

Implementation Guide

Feature 1: Search Text in Email Body

This feature enables searching for specific text within an email’s subject and body.

Overview

We’ll demonstrate how to configure GroupDocs.Watermark to search through different parts of an email message using Java code.

Step 1: Define Document Paths

Set up your input and output paths for handling emails:

String inputDocumentPath = "YOUR_DOCUMENT_DIRECTORY/message.msg";
String outputDocumentPath = "YOUR_OUTPUT_DIRECTORY/output_message.msg";
Step 2: Set Up Load Options and Watermarker

Initialize the EmailLoadOptions and Watermarker to work with your email document.

EmailLoadOptions loadOptions = new EmailLoadOptions();
Watermarker watermarker = new Watermarker(inputDocumentPath, loadOptions);
Step 3: Create Search Criteria

Define criteria for searching text. We’ll use a case-insensitive search for the keyword “test”:

import com.groupdocs.watermark.search.SearchCriteria;
import com.groupdocs.watermark.search.TextSearchCriteria;

SearchCriteria criteria = new TextSearchCriteria("test", false);
Step 4: Specify Search Locations

Configure the search to cover both the subject and body of emails:

watermarker.getSearchableObjects().setEmailSearchableObjects(
    EmailSearchableObjects.Subject |
    EmailSearchableObjects.HtmlBody | 
    EmailSearchableObjects.PlainTextBody);
Step 5: Execute Search and Clear Watermarks

Perform the search and remove any found watermarks:

import com.groupdocs.watermark.search.PossibleWatermarkCollection;

PossibleWatermarkCollection watermarks = watermarker.search(criteria);
watermarks.clear();
Step 6: Save Changes

After processing, save your changes to a new document:

watermarker.save(outputDocumentPath);
// Close the Watermarker instance to release resources
watermarker.close();

Troubleshooting Tips

  • Common Issue: If search results are empty, ensure the text is present in the email body or subject.
  • Performance Tip: Optimize by limiting searches to necessary sections of emails.

Feature 2: Load Email Document Options

This section discusses how you can set up additional options when loading an email document for processing with GroupDocs.Watermark.

Overview

Configuring load options enables more control over how documents are handled, such as specifying password protection or encoding settings.

Step 1: Configure Load Options

Here’s a basic setup for EmailLoadOptions:

EmailLoadOptions loadOptions = new EmailLoadOptions();
// Additional configurations can be added here.

Key Configuration Options

  • Password Protection: Specify passwords if your emails are encrypted.
  • Encoding Settings: Define specific encoding types as needed.

Practical Applications

Use Case 1: Automated Email Processing

Automate the filtering and processing of bulk email data to find specific content efficiently.
