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. ImageScience -- http://seattlerb.rubyforge.org/ImageScience.html Mini-Magick -- http://rubyforge.org/projects/mini-magick/ RMagick -- http://rmagick.rubyforge.org/ It looks like a lot of people are seeing problems with memory usage if they are invoking RMagick often. Mini-Magick looks like it''...

hi ya all, i am tryin to deploy imagescience on a small app i made. and i found no good tutorial/introduction on how to do so... i installed the gem and all the dependencies but when I try to call the ImageScience object: uninitialized constant ImageScience some code sample can save me. thanks all, K -- Posted via http://www.ruby-forum...

I''ve tried migrating acts_as_attachment to attachment_fu (just to see if I could replace RMagick with ImageScience+FreeImage), but the quality of the thumbnails is just horrendous, blurred beyond recognition (downscaling a 1280x1024 to a few considerably smaller thumbnails). Changing attachment_fu to use RMagick again and the thumbnails were crispy sharp again. I was wondering if this has anything...

Hi, I have mongrel 0.3.14, with ruby 1.8.5, rails 1.1.6 and mongrel cluster 0.2.1, on debian sage 3.1 with apache 2.0, and fastthread 0.6.1. I am load balancing 3 mongrel processes using the random port trick. When I start mongrel the processes have about 60MB, but after some hour of usage the memory ballons upto more than 180MB and the site becomes terribly slow. Forcing me to restart mongrel

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,

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 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

Hi, which is the best way to upload an image, keep that and also make a thumbnail? The images should not be stored in the database, but as normal image files in a specific directory. I think that for the thumbnail i should use rmagick, but for the upload ? (something which work with and without javascript, in every browser) Thanks :) -- Posted via http://www.ruby-forum.com/.

I''ve been getting a bunch of reports about the latest Rails "leaking" memory more than before. Please fill out this survey: 1) Have you noticed an increase in memory usage with the latest Rails 1.2? 2) Have you changed anything else in your application? a) No, really, don''t be a dumbass like the lusers you hate. Go look at your svn logs and really figure out if

I''m looking at possibly going with Image Science (http:// seattlerb.rubyforge.org/ImageScience.html) for an application in development. I''ve heard that it is a lot less overhead than RMagick and we really don''t have any complex image requirements. Are there any folks out there using Image Science that could chime in with some feedback? Also, I have a couple specific...

Hey everyone, I''ve been dealing with Rails 3, Paperclip and Windows 7 for a few nights now and don''t feel like I''m actually getting anywhere. I''ve hit config issue after config issue and it''s a bit of a nightmare. Can anyone recommend any other gems that will accomplish the same thing?

I just installed attachment_fu and for some reason, it seems to be looking in the wrong location for my images. I have a Product model that belongs to a photo model. the photo model has the attachment_fu installed and configured like so: class Photo < ActiveRecord::Base has_attachment :content_type => :image, #Allow standard image formats :path_prefix

Hey, I know it''s a basic question and I do not want a discussion about which one is the best in general, I only want to know which OS you''d recomment for programing in Rails and to do webdesign.

I''ve been trying to track down the culprit of erratic behaviour and crashes on my production server (which is split into a number of Xen instances), so set up a staging server so that I could really try to get to the bottom of it. The staging server (also split with Xen) is set up pretty much identically as far as the mongrel_cluster server is concerned (the production box has two

Hello, I''m running a Rails application which must sort and manipulate a lot of data which are loaded in memory. The Rails app runs on 2 mongrel processes. When I first load the app, both are 32Mb in memory. After some days, both are between 200Mb and 300Mb. My question is : is there some kind of garbage collector in Mongrel? I never see the two Mongrel processes memory footprint
