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();
// Specify an absolute or relative path to your document. Ex: "C:\\Docs\\message.msg"
Watermarker watermarker = new Watermarker("message.msg", loadOptions);
EmailContent content = watermarker.getContent(EmailContent.class);
// Set the plain text body
content.setBody("Test plain text body");
// Set the html body
content.setHtmlBody("<html><body>Test html body</body></html>");
// Set the email subject
content.setSubject("Test subject");
// Save changes
watermarker.save("message.msg");
watermarker.close();
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();
// Specify an absolute or relative path to your document. Ex: "C:\\Docs\\message.msg"
Watermarker watermarker = new Watermarker("message.msg", loadOptions);
EmailContent content = watermarker.getContent(EmailContent.class);
File imageFile = new File("sample.jpg");
byte[] imageBytes = new byte[(int) imageFile.length()];
InputStream imageInputStream = new FileInputStream(imageFile);
imageInputStream.read(imageBytes);
imageInputStream.close();
content.getEmbeddedObjects().add(imageBytes, "sample.jpg");
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("message.msg");
watermarker.close();
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();
// Specify an absolute or relative path to your document. Ex: "C:\\Docs\\message.msg"
Watermarker watermarker = new Watermarker("message.msg", 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.save("message.msg");
watermarker.close();
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();
// Specify an absolute or relative path to your document. Ex: "C:\\Docs\\message.msg"
Watermarker watermarker = new Watermarker("message.msg", loadOptions);
SearchCriteria criteria = new TextSearchCriteria("test", false);
// Specify search locations
watermarker.getSearchableObjects().setEmailSearchableObjects(EmailSearchableObjects.Subject | EmailSearchableObjects.HtmlBody | EmailSearchableObjects.PlainTextBody);
// Note, search is performed only if you pass TextSearchCriteria instance to FindWatermarks method
PossibleWatermarkCollection watermarks = watermarker.search(criteria);
// Remove found text fragments
watermarks.clear();
// Save changes
watermarker.save("message.msg");
watermarker.close();
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
EmailLoadOptions loadOptions = new EmailLoadOptions();
// Specify an absolute or relative path to your document. Ex: "C:\\Docs\\message.msg"
Watermarker watermarker = new Watermarker("message.msg", loadOptions);
EmailContent content = watermarker.getContent(EmailContent.class);
// List all direct recipients
for (EmailAddress address : content.getTo())
{
System.out.println(address.getAddress());
}
// List all CC recipients
for (EmailAddress address : content.getCc())
{
System.out.println(address.getAddress());
}
// List all BCC recipients
for (EmailAddress address : content.getBcc())
{
System.out.println(address.getAddress());
}
watermarker.close();
