Append Encoded Binary Data to StringBuilder

Demonstrates how to append encoded binary data to the contenets of a StringBuilder. Ruby

require 'chilkat'

success = false

bd = Chilkat::CkBinData.new()

success = bd.LoadFile("qa_data/jpg/starfish.jpg")
if (success == false)
    print "Failed to load file." + "\n";
    exit
end

# For example, let's say we want construct simple JSON containing the base64 representation of the above JPG file.
sb = Chilkat::CkStringBuilder.new()
sb.Append("{ \"jpg\": \"")
# GetEncodedSb appends the enocded representation of the binary data to the StringBuiler passed in the 2nd arg.
bd.GetEncodedSb("base64",sb)
sb.Append("\" }")

print sb.getAsString() + "\n";

# Output looks like this:
#  { "jpg": "/9j/4AAQSkZJRgABAg...rcQ+vo//2Q==" }
