# file: mimeBinaryBody.rb

require 'chilkat'

# A MIME body can be loaded with the contents of a file.
# The Chilkat MIME component automatically maps the file extension
# to a content-type.  If no mapping is found, the content-type is
# set to application/octet-stream and the content-transfer-encoding
# is set to base64.  Otherwise the content-transfer-encoding
# is set to what is appropriate for the file contents.
# 
# Note: content-transfer-encoding and content-type can be updated
# after loading the body from a file by simply setting the ContentType
# and Encoding properties.

		
mime = Chilkat::CkMime.new()
mime.UnlockComponent("anything for 30-day trial")
	    
# Load the MIME body with a GIF file.
mime.SetBodyFromFile("images/dudeRuby.gif")
		
# Print the MIME:
print mime.mime() + "\n\n"

# Prints this:
# content-disposition: attachment;
# 	 filename="dudeRuby.gif"
# content-transfer-encoding: base64
# content-type: image/gif;
# 	name="dudeRuby.gif"
