Hey mates,

I´m a newbie to Ruby and Rails. But I´m a programer since few years. So  
my problem is, that I will try to read a lot of photos with RMagick.

require ‘rubygems’ # if installed via Gems  
require ‘RMagick’  
include Magick

exit 1 if ARGV.length != 1

files = Dir.new(ARGV[0])

exit 1 unless files

files.each do |file|  
next unless file =~ %r{.jpg$}i

puts ARGV[0]+file  
img = Image.read(ARGV[0]+file).first  
img\_orient = img.auto\_orient # turn a copy  
img\_gallery = img\_orient.resize\_to\_fit(1024,1024) # scales a copy down  
end

Don´t be scared about my code… 😉

Ok… normaly I think, I can read every image - given from the directoy  
in ARGV[0]. In C or C++ I know, that in every cicle of the loop img,  
img\_orient, img\_gallery will be overwritten. But after 12-15 image  
(appr. 2.5 MB =\> 30-40 MB ) the memory-allocation is incredible high…  
so why?!?

I hope, that anyone can help me.

thanks!

Also, if you’re using RMagick 2:
