similar to: mini_magick - 2 clarifications

Hi, Mini-Magick breaking. I have installed mini-magick gem. Here is my sample program require ''rubygems'' gem ''mini_magick'' include minimagick image = MiniMagick::Image.from_file(''./fun.jpg'') image.resize "100x100" image.write(''./funthumb.jpg'') Output: test.rb:3: undefined local variable or method

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

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

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/.

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

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 =

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 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 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 =>

I''m trying to setup a mongrel cluster. I''m relying on information collected from a number of sources but I''m relying heavily on http://mongrel.rubyforge.org/docs/apache.html. I have noted that a number of sources mention the necessity of having the mod_balancer module installed in Apache. However, my primary source makes no mention of this; but instead, mentions only

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

Suppose that I want to have a block of default content within a template that is replaced with the content of a specific partial only if that partial exists. Obviously there is the brute force approach of simply rendering the default content unless the relevant partial file exists in which case the relevant partial is rendered instead. I suspect that there may be a more elegant way to skin this

I have posted this here also: http://beast.caboo.se/forums/2/topics/ 823 I''m writing this for a custom application that uses attachment_fu but I thought it might interest some people here who are have problems with rmagick or image_science. rmagick is causing large memory spikes for my application and my host will not install image_science, I tried out image_science locally and the

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

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

A question about the layout of structs: I decided to make my vtables out of structs rather than arrays. In other words, instead of being a table of opaque pointers, I decided to individually declare each entry with the correct type for that method. I figure that the various optimizers could do a better job if I preserve the type info. OK, so we come to the issue of inheritance: Suppose I have

Hello, I am frastruated with this graph, just cannot get what I need. Thank you for any suggestions or help. I really appreciate it. I wrote the following code, but there are 3 problems 1, the red line is added on the graph but without any marker on the y-axis. I want to display the number '.1361' on the y-axis. So people can easily tell 'method 2' gets a constant estimate, which

Is there a way to call a method if I only have a string that contains the method name. For example: @methods = [''method1'', ''method2'', ''method3''] @step = 1 # I want to call method2 which has a definition in this class -- Posted via http://www.ruby-forum.com/.

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
