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

Hi there, I''m writing a little application that parses an image file and extracts the camera settings from the file (the EXIF data) and saves all the fields to the database. The idea is that after awhile people will be able to search based on camera make, model, lens settings, etc... and all the pictures that meet those requirements will be displayed. The picture is stored on the file

I see that the SVN version of the excellent file_column plug-in can create thumbnails using the url_for_image_column helper. This uses Rmagick to create the thumbnail... Quick question... Let''s say the file is a TIFF image - can the helper create a JPG version of the thumbnail for display in the browser? Curious if the plug-in can handle that transform with some creative use of the

I''ve based my code on the Agile example for uploading files, pages 362-365. I''ve successfully loaded the Picture object to the database, but I come unstuck when trying to replicate this for a thumbnail version of the original image: thumbnail = Thumbnail.new thumbnail.name = ''thumbnail_'' + @picture.name.to_s

Hi, I need to create a preview of a PDF upload to a CMS I''m building. Does anyone know how to create a thumbnail of the first page of a PDF using RMagick?

Hi, I''m brand new to RMagick (and pretty new to Rails for that matter!). Right now, site owners are allowed to upload product and ingredient photos to the website. Everything works great, ingredients are sized down and proportioned correctly...the problem is that the resulting images are so blurry! So I''ve been doing some research and it looks like Paperclip::Processor may be the

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

I''m using Attachment_Fu to save several thumbnails of a photo (resizing with ImageMagick) But when I try to crop them, nothing seems to happen to the file I want to drop and no error messages. I check the file timestamp of the thumbnail I want to crop and it looks updated. What''s strange is that ALL the other thumbnails and the original image''s file timestamps are

I installed ImageMagick 6.5.6 and all seems to be installed ok. I downloaded ImageMagick 6.5.6 I entered $ ./configure and everything seems OK.

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,

Hello friends, I have configured attachment_f. It''s working fine on Local(development) system but giving problem on production. Basically on production the attachment_fu is not able to generate thumbnail image it saving the original size image. Below is the configuration. has_attachment :content_type => :image, :storage => :file_system, :max_size

I want to install Rmagick on Ubuntu 7.10, but i am getting this error when running gem install rmagick: Can''t install RMagick 2.2.0. You must have ImageMagick 6.3.0 or later.

I am using RMagick to convert some files served up by a rails app from tiff''s to pdf''s on the fly. I have Imagemagick installed but was having trouble with some of the conversions. I tried installing GraphicsMagick and running the conversions manually and they work fine using GraphicsMagick. (They do not work properly even manually with ImageMagick.) I can''t see

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 unzipped simple captcha in vendor/plugins Then I did >rake simple_captcha:setup Gave error: rake aborted! no such file to load -- RMagick2.so SO I thought Rmagick has to be installed.

Tracked down the source of my problem... It seems that Rmagick isn''t properly cropping/resizing GIF or PNG images when uploaded via file_column. I can upload JPG files just fine. Originally I had installed ImageMagick via Debian''s apt-get and built the rmagick gem using "gem install rmagick". This wasn''t working so I uninstalled ImageMagick and tried to
