Hello

I am having a problem with IO.pipe

I have the following code:

…  
img = read\_pipe.read()  
im = Magick::Image::read\_inline(Base64.b64encode(img)).first  
im.format = “PNG”  
puts “1”  
read\_pipe, write\_pipe = IO.pipe  
puts “2”  
im.write(write\_pipe)  
puts “3”  
write\_pipe.close()  
puts “4”  
…

My problem is that when i try to close the write\_pipe, the process seems  
to stop.  
In the console, I have the “puts ‘3’” printed but not the “puts ‘4’” and  
after that nothing happens.

Anyone with an idea about this problem?
