ICC profile name

[mattias]

I'm looking for a way to extract/detect the ICC profile name of an image. I have no problem getting the profile itself - but how can I determine which profile it is.

Is this realy not possible?

Maybee someone can help me with pointers to th format of the ICC profile format? Does anyone have an idea of how one could parse it? Is it xml?

Cheers

Hi Mattias,

Here's pointer to the latest ICC spec. It's a binary format, not XML. Good luck!

So I read the specs and wrote this little test script. Have only tested it with a small number of files but it looks like its working.

Code: Select all

#!/usr/bin/env ruby -w
profile = Array.new

# Read the profile
data = IO.read 'profile'

# Read it into an array
data.each_byte { |b| profile.push(b) }

# Count the number of tags
tag_count = profile[128,4].pack("c*").unpack("N").first

# Find the "desc" tag
tag_count.times do |i|
  n =  (128 + 4) + (12*i)
  ts = profile[n,4].pack("c*")
  if ts == 'desc'
    to = profile[n+4,4].pack("c*").unpack("N").first
    t_size = profile[n+8,4].pack("c*").unpack("N").first    
    tag = profile[to,t_size].pack("c*").unpack("Z12 Z*")
    puts tag.inspect
  end
end
