Set a MIME Body from Transfer-Encoded Text
See more MIME Examples
Demonstrates the Chilkat Mime.SetBodyFromEncoded method, which sets the body from already transfer-encoded text. The first argument is the encoding (base64 or quoted-printable) and the second is the encoded text.
Background: Sometimes you already hold content in its encoded form — a Base64 string from a database or another API — and re-decoding just to have Chilkat re-encode it is wasteful. This method stores the encoded text as-is and records the matching transfer encoding, so the body is correct without a needless round trip. Only the standard reversible encodings, Base64 and quoted-printable, are accepted.
