similar to: uninitialized constant MiniMagic (NameError)

I can''t for the life of me figure this out. Been banging my head on this since the weekend, and can''t see what I''m doing wrong. This code works: image.resize("640x480") image.write(path) I run this and I get the resized file just fine. This doesnt work at all: width = 200 height = 100 dimensions = "#{width}x#{height}"

I followed the instructions on Mike Clark''s weblog and everything works perfectly except the thumbnail column in my DB is alwas NULL. I''m using S3 as my storage system. Anyone else having this issue with thumbnails? has_attachment :content_type => :image, :storage => :s3, :max_size => 500.kilobytes, :resize_to =>

Hi, I''m using Mini Magick and that attachment_fu plugin to resize images that the user uploads. Everything looks okay in my code, but I get a core dump every time an image is uploaded. The file successfully posts to the application, I can see that the original file gets copied into the folder correctly. It appears that it dumps immediately after that. I''m using Mongrel behind

1. I have seen examples similar to the following: image = MiniMagick::Image.from_file("input.jpg") image.resize "100x100" image.write("output.jpg") I''m assuming that image.resize is a method. Is there any significance to the fact that the argument for that method is not enclosed in parenthesis while the other are? Examples seem to be consistent --

I''d like to implement a system in a Rails app where I allow the user to upload an image file, and then the app takes that image and manipulates it, saving a thumbnail, small, and original size version of the file to the server. How would I go about doing that? Thanks, Jeff -- Posted via http://www.ruby-forum.com/.

Hi, everyone! I have been recently hit by ImageMagick/Rmagick memory leak issues. I know I can lesson the problem by manually starting up GC each time I use Rmagick library but ImageMagick seems to use way too much memory nevertheless. (on shared hosting setup anyway) Is there a decent replacement for ImageMagick library? I used to think ImageMagick was quite efficient because its

I am having issues loading imagemagick and rmagick on webfaction. I have installed a rails app called balder that organizes images. my main problem is that i can''t seem to upoload the image sthrough balder. balder uses imagemagick and rmagick when i use the console and do this: irb(main):003:0> require ''RMagick'' => nil I don''t think rmagick is

I know that Zed has made mention of the fact that using RMagick with mongrel and rails is a bad thing. I''m currently using FlexImage (which in turn uses RMagick) on my application and really haven''t had too many problems. We get a restart for memory usage every 8-10 hours on one mongrel of twelve running, but I''m not sure if that''s an RMagick issue. Either way,

In the rails app I''m making, I dropped MiniMagick into the vendor folder (vendor/mini_magick). In my controller, when I call: image = MiniMagick::Image.from_file(path) ...I get a "uninitialized constant MiniMagick" error. From what I can tell, installing a plugin such as this should be as simple as dropping it into the vendor folder, then accessing its functions from the

Hi, would anyone have any advices on the next? I allow users to upload images to my app. I''m using attachment_fu and MiniMagick. There''s two things that I''d like to do: 1- No matter what format the original file is I''d like to save it in jgp format. 2- I want to keep all images limited to say 1000px width, so resize if they are bigger. Is there a way to do

I''m going to be generating thumbnails from user uploaded images. I''m looking around at the libraries available to do this sort of thing and there are three that look promising.

Hi. I''m a fairly new mongrel user and have a scenario that I wanted to run by you all, see if anyone''s synapses connect -- mine def. aren''t! I''m running a fairly simple rails app through a mongrel cluster (2 mongrels). This site is consistently sloooow -- memory on the server is regularly paging (and shouldn''t be). ssh-ing in and running top shows

We just upgraded to Ruby 1.8.4 and Rails 1.1. It works fine on my Mac OSX, but in Windows, Rails spits out errors like "Invalid char `\002'' in expression". Apparently, Ruby or Rails on Windows has a problem parsing tab characters. This seems to be a common problem: http://softiesonrails.com/articles/2006/04/27/spaces-not-tabs However, the only recommended solutions seems

I''ve got a model with :has_attachment with content of image type. When I''m trying to save an image, the following line in the log appears: Exception working with image: ImageMagick command (identify "C:/ WINDOWS/TEMP/minimagick2860-0") failed: Error Given Minimagick is installed properly or seems to be. At least, all mini- magick tests except those with some php-file

I am using BackgrounDRb to resize images after they are accepted into our system. However, it has become clear that this creates a memory leak. I''m not sure exactly where the leak exists, but I don''t think it''s in my own code as it is presently being used in production and has resized thousands of images without a leak occurring, thanks to calling GC.start

Hello, Recently attachment_fu stopped resizing images for me. I''m puzzled because before today it was resizing them and I don''t know what''s changed. Here''s my code: class Product < ActiveRecord::Base has_attachment :content_type => :image, :storage => :file_system, :max_size => 18.megabytes,

Posting here is kind of a last resort: has anyone used Minimagick with Ruby on Rails, and gotten it working correctly? I hate posting a "bug" problem but I''m not if it''s *my* problem, or a problem with Imagemagick and RoR 1.0, which I just installed (upgraded from 0.13.1). Basically, when I try to run the most basic MM command in ROR: image =

Hi, I need a relatively simple image api for the app I''m writing. I need to copy photos, rename them, and re-size them to put them in a standard format. I tried using RMagick/Imagemagick, but the photos would be corrupted on re-size, so I''m looking for some suggestions. -- Posted via http://www.ruby-forum.com/.

I have a requirement that can''t be that outrageous.... I want to be able to upload an image, and have multiple thumbnails be created for each. Then, I want to post process each image (the main image plus the thumbnails) to add borders. The trick is that the borders need to be different for each image. I thought I could use the after_resize handler, but when I try to add a border to

Hi After having updated some GEMS I get `load_missing_constant'': uninitialized constant ActiveSupport::Cache (NameError) on starting the server of a freshly generated rails project. Before, I already had Rails 2.3.2 projects succesfully running, now all of them generate this error. These are my GEMS: actionmailer (2.3.2, 2.2.2, 2.1.2, 2.1.1, 2.1.0) actionpack (2.3.2, 2.2.2, 2.1.2,
