Modifying body and subject of email message

GroupDocs.Watermark also allows you to modify the body and subject of an email message. Below is the code sample to modify body and subject of an email Message:

advanced_usage.add_watermarks_to_email_attachments.EmailUpdateEmailBody

EmailLoadOptions loadOptions = new EmailLoadOptions();                                                 
// Constants.InMessageMsg is an absolute or relative path to your document. Ex: "C:\\Docs\\message.msg"
Watermarker watermarker = new Watermarker(Constants.InMessageMsg, loadOptions);                        
                                                                                                       
EmailContent content = watermarker.getContent(EmailContent.class);

// Set the html body

// Set the email subject

watermarker.save(Constants.OutMessageMsg);

Embedding image to email message body

GroupDocs.Watermark also provides the feature of embedding images in the body of the email message. Following is the code sample for embedding an image in an email:

advanced_usage.add_watermarks_to_email_attachments.EmailAddEmbeddedImage

EmailLoadOptions loadOptions = new EmailLoadOptions();                                                                              
// Constants.InMessageMsg is an absolute or relative path to your document. Ex: "C:\\Docs\\message.msg"                             
Watermarker watermarker = new Watermarker(Constants.InMessageMsg, loadOptions);                                                     
                                                                                                                                    
EmailContent content = watermarker.getContent(EmailContent.class);                                                                  
                                                                                                                                    
File imageFile = new File(Constants.SampleJpg);                                                                                     
byte[] imageBytes = new byte[(int) imageFile.length()];                                                                             
InputStream imageInputStream = new FileInputStream(imageFile);                                                                      
imageInputStream.read(imageBytes);                                                                                                  
imageInputStream.close();

EmailEmbeddedObject embeddedObject = content.getEmbeddedObjects().get_Item(content.getEmbeddedObjects().getCount() - 1);            
content.setHtmlBody("<html><body>This is an embedded image: <img src=\"cid:" + embeddedObject.getContentId() + "\"></body></html>");
watermarker.save(Constants.OutMessageMsg);                                                                                          
                                                                                                                                    
watermarker.close();                                                                                                                

Removing all embedded images from email message body

You can also remove the embedded images from the body of the email message. Below is the code for removing embedded images:

advanced_usage.add_watermarks_to_email_attachments.EmailRemoveEmbeddedImages

EmailLoadOptions loadOptions = new EmailLoadOptions();                                                                
// Constants.InMessageMsg is an absolute or relative path to your document. Ex: "C:\\Docs\\message.msg"               
Watermarker watermarker = new Watermarker(Constants.InMessageMsg, loadOptions);                                       
                                                                                                                      
EmailContent content = watermarker.getContent(EmailContent.class);                                                    
for (int i = content.getEmbeddedObjects().getCount() - 1; i >= 0; i--)                                                
{                                                                                                                     
    if (content.getEmbeddedObjects().get_Item(i).getDocumentInfo().getFileType() == FileType.JPEG)                    
    {                                                                                                                 
        // Remove reference to the image from html body                                                               
        String pattern = "<img[^>]*src=\"cid:" + content.getEmbeddedObjects().get_Item(i).getContentId() + "\"[^>]*>";
        content.setHtmlBody(content.getHtmlBody().replaceAll(pattern, ""));                                           
                                                                                                                      
        // Remove the image                                                                                           
        content.getEmbeddedObjects().removeAt(i);                                                                     
    }                                                                                                                 
}

watermarker.close();                                                                                                  

Searching text in email message body or subject

Using GroupDocs.Watermark, you can also search for a text in the subject as well as in the body of the email message. Following is the code sample for searching text in Email Message:

advanced_usage.add_watermarks_to_email_attachments.EmailSearchTextInBody

EmailLoadOptions loadOptions = new EmailLoadOptions();                                                                                                               
// Constants.InMessageMsg is an absolute or relative path to your document. Ex: "C:\\Docs\\message.msg"

watermarker.getSearchableObjects().setEmailSearchableObjects(EmailSearchableObjects.Subject | EmailSearchableObjects.HtmlBody | EmailSearchableObjects.PlainTextBody);

Listing all message recipients

GroupDocs.Watermark also allows listing all the message recipients using methods getTo(), getCc() and getBcc() as shown in the following code sample.

advanced_usage.add_watermarks_to_email_attachments.EmailListRecipients
