Hi,
I am using Paperclip, and attempting to do a resize of images uploaded
by the user:
My model looks like this:
class MyImage < ActiveRecord::Base
has_attached_file :pic,
:styles => {
:sidebar => ["140x1^", :jpg],
:listable => ["1x200^", :jpg]
},
:storage => :s3,
:s3_credentials => "#{RAILS_ROOT}/config/s3.yml",
:path => ":attachment/:id/:style.:extension"
# lots more code
end
I updated Paperclip's error reporting so that it gives me the stderr
from the ImageMagick command. When I post to create with a valid .jpg
file, I get the following error message coming out of ImageMagick
(this is the stderr using Open3::popen3):
convert: invalid argument for option `140x1^': -resize
I'm wondering if Heroku has an older version of ImageMagick
installed? I searched a bit and noted that, "(The ^ feature is new as
of IM 6.3.8-2.)"[see 1]
Otherwise, any other insights from anyone?
Thanks in advance
- Luke
