image processing - Multi-file to Multi-page TIFF from large collection -


struggling consolidate multiple files multi-page tiffs using pyliff, libtiff, or work.

i'm consolidating thousands of files arbitrary 8 digit ids followed page numbers:

directory named date \images\1999\10\14

group of files 1 01234567_0001.tif, 01234567_0002.tif, 01234567_0003.tif

group of files 2 07654321_0001.tif, 07654321_0002.tif

following conversion i'd have 2 files:

  1. 01234567.tif (3 page mulipage tiff file)
  2. 07654321.tif (2 page multipage tiff file)

and on. please give guidance on script , consolidation segregate first 8 digits, merge files unique 8 digit number, , rename new (consolidated) file appropriate 8-digit-number.tiff

i realize seems without effort. have many disparate scripts , approaches muddy waters of forum.

the solution ruby able provide (imagemagick did conversion). hope helpful others: 

#!/usr/bin/env ruby  require 'find' require 'set'  start_path = argv.shift || "~\desktop\in" output_path = argv.shift || "~\desktop\out"  unless file.exist? start_path   raise "cannot catalog contents; '#{start_path}' not exist" end  unless file.exist? output_path   raise "cannot catalog contents; '#{output_path}' not exist" end  #make sure output directory has trailing slash unless output_path =~ /\\$/   output_path += "\\" end  documents = set.new  #look @ each file find.find(start_path) |file_path|    #look document pattern   if file_path =~ /^(.*?(\d{8}))_\d{4}.tif/     #track can unique document list     documents.add({:path => $1, :name => $2})   end end  documents.each |doc|   command = "convert #{doc[:path]}*.tif* #{output_path}#{doc[:name]}.tif"   puts command   `#{command}` end
