[Locomotive-users] RMagick again

[Timo Hoepfner]

Hi,

You can limit the number of pages read into memory to "my_limit" when  
using ::Magick::Image.read(path_to_file) 
{self.number_scenes=my_limit}. This somehow doesn't work when using  
the rails112rmagick_x86 bundle. It works fine with Locomotive 1 and  
the rails-1.0.0-max bundle.

Locomotive 1:

 >> ::Magick::Image.read("/Users/admin/a.pdf").size
=> 5
 >> ::Magick::Image.read("/Users/admin/a.pdf") 
{self.number_scenes=1}.size
=> 1


Locomotive 2:

 >> ::Magick::Image.read("images/a.pdf").size
=> 5
 >> ::Magick::Image.read("images/a.pdf"){self.number_scenes=1}.size
=> 5


Any ideas? I just locked-up my machine for half an hour by running  
the last statement on a 150 page PDF file...


I tried upgrading to the latest rmagick, but I got the following error:
