# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# First load image data into memory.
# This example loads image data from a file.
# However, your application could get the image data from any other source, such as
# from a database.
fac = chilkat2.FileAccess()

# imageBytes is a memoryview
imageBytes = fac.ReadEntireFile("qa_data/jpg/starfish.jpg")

# The mailman object is used for sending and receiving email.
mailman = chilkat2.MailMan()

# Use your SMTP server hostname.  This example uses office365, but it could be any SMTP server..
mailman.SmtpHost = "outlook.office365.com"
mailman.SmtpPort = 587
mailman.StartTLS = True

# Set the SMTP login/password
mailman.SmtpUsername = "OFFICE365-SMTP-LOGIN"
mailman.SmtpPassword = "OFFICE365-SMTP-PASSWORD"

# Create a new email object
email = chilkat2.Email()
email.Subject = "HTML Email with Image Loaded from In-Memory Bytes"
email.From = "Chilkat Support <my-office365-user@mydomain.com>"
email.AddTo("Chilkat Support","support@chilkatsoft.com")

contentIdStarfish = email.AddRelatedData("starfish.jpg",imageBytes)
if (email.LastMethodSuccess != True):
    print(email.LastErrorText)
    sys.exit()

# The src attribute for the image tag is set to the contentIdStarfish:
sbHtml = chilkat2.StringBuilder()
sbHtml.Append("<html><body><p>This is an HTML email with an embedded image.</p>")
sbHtml.Append("<p><img src=\"cid:CONTENT_ID_STARFISH\" /></p></body></html>")
