How to make a pdf signature visible (along with validity icons) - ruby

Question

Initially the question was about making a pdf signature visible with Ruby. That i can do now with the code below.
My only problem now is with the validity icon. It shows up on FoxIt Reader, but not on Acrobat Reader (i'm using XI right now)
This is what I have right now
require 'openssl'
begin
require 'origami'
rescue LoadError
ORIGAMIDIR = "C:\RailsInstaller\Ruby1.9.3\lib\ruby\gems\1.9.1\gems\origami-1.2.4\lib"
$: << ORIGAMIDIR
require 'origami'
end
include Origami
def draw_signature(name, attr = {})
load! if #instructions.nil?
x, y = attr[:x], attr[:y]
#instructions << PDF::Instruction.new('q')
#instructions << PDF::Instruction.new('cm', 1, 0, 0, 1, x, y)
#instructions << PDF::Instruction.new('Do', name)
#instructions << PDF::Instruction.new('Q')
end
def SignPdf(inputF)
#inputfile = String.new(inputF)
outputF = #inputfile.insert(inputF.rindex("."),"_signed8")
certFile = "cert.pem"
rsakeyFile = "pk.pem"
passphrase = "mypass"
key4pem=File.read rsakeyFile
key = OpenSSL::PKey::RSA.new key4pem, passphrase
cert = OpenSSL::X509::Certificate.new(File.read certFile)
pdf = PDF.read(inputF)
page = pdf.get_page(1)

EDIT 2
Following mkl intervention, i went a little further into the source...
I noticed the xobject.rb file, with the following code for drawing an image
def draw_image(name, attr = {})
load! if #instructions.nil?
x, y = attr[:x], attr[:y]
#instructions << PDF::Instruction.new('q')
#instructions << PDF::Instruction.new('cm', 300, 0, 0, 300, x, y)
#instructions << PDF::Instruction.new('Do', name)
#instructions << PDF::Instruction.new('Q')
end
I have then created the method below on that same file
def draw_stream(name)
load! if #instructions.nil?
#instructions << PDF::Instruction.new(name)
end
which allows me to control the stream from its input.
I also went to ISO32000:2008, and iterated a bit thorugh my code, but got nowhere further.
Here is my currently generated pdf file , and the part of it that relates to signatures:

What am I missing?

Answer 1

Sometimes, a man just need to know how to actually understand what he reads over and over again...
The ppkappearances file had it all there. I didn't even went as far as I expected i would have with complying with the dictionary structure they recommend there.
I just needed to add the n1 and n3 layers, and the stream content could even be just "% DS Blank". the question mark string stream you find was the one i took from PdfSignatureAppearance.cs file from iText solution. If I use that one Foxit Reader presents the question mark (even if the signature is valid). For Adobe it doesn't matter i use that or DSBlank.

What a fight!
I feel like saying :
In the end, the winners are the ones that you will find standing in the middle of the battle field. Sadly looking around them into the battle field, and wondering why it had to be like that. Only if they knew how to read...then nothing of that would have happened. At the same time though, if it wouldn't have happened, they wouldn't know they didn't know how to read with the right focus.
