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 have a model using attachment_fu (via has_attachment) and I''m creating thumbnails for the attached images. I have an extra field ''foo'' that I''m validating on create with validates_presence_of :foo. One problem arises when I upload an image: The ''foo'' is not propogating down to the thumbnails. What should I put in my model to grab the

Browsing the net for one thing unexpectedly brought me to two good and useful documents: (1) Guide to the Secure Configuration of Red Hat Enterprise Linux 5 http://www.nsa.gov/ia/_files/os/redhat/rhel5-guide-i731.pdf Revision 4.1 February 28, 2011 (2) Hardening Red Hat Enterprise Linux 5 http://people.redhat.com/sgrubb/files/hardening-rhel5.pdf Updated 12 August 2010 Gnome Thumbnail system is

the full-size pics upload OK, but no thumbs or resizing. There are no errors or exceptions that I can see, just not getting any thumbnails. The DB column ''thumbnail'' is always NULL rmagick-1.15.6 is freshly installed. I have the :thumbnails stuff setup per http://weblog.techno-weenie.net/articles/acts_as_attachment/thumbnailing using a model like this: class EventPic

Can anyone point me to a resource for hand coding some sql so I can create my own for the following models: I''m using single table inheritance to store related objects eg: Thumbnail < Image < File :: ActiveRecord:Base Image has_many thumbnails Thumbnail has_one image When I come to list thumbnails I''d like to be able to: 1. List all images relating to a product 2.

Hi, I''m having trouble with attachment_fu on windows not generating any thumbnails on the fly. I started out trying to incorporate this into my app without success then tried implementing Mike Clarke''s tutorial (http://www.clarkware.com/cgi/blosxom/2007/02/24) and got the same problem. I have resolved some gotchas I found in the "attachment_fu on Windows" thread

Is there a way explorer can show thumbnails? Im using a photo editor program in wine and i need to see the pictures thumbnails to select multiple photos and open it faster.

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 was struggling for a function where only 1 thumbnail should be active and others inactive when clicked on the particular thumbnail. code: 1. view: 2. <script type="javascript"> 3. function PlayVideo_options(videoFile, id) { 4. document.getElementById(id).className = ''video_option active_video''; 5. } 6. </script> 7. 8.

I am using attachment_fu to create thumbnails, and it is working great. However, I am have a view with all my users thumbnails displayed and am trying to make it so when you click on a thumbnail of their avatar, it shows that users profile. In order to accomplish this I have saved a user_id identifier for each avatar, but the problem is that attachment_fu only saves this user_id for the main

Hi, 1. How to resize an image uploaded by a web form before saving it to the disk? (i need all uploaded images to have similar size) 2. How to create thumbnails? Is it enough if i specify small size of the image in html or would the image look horrible? Can i do it somehow in ''realtime'' using javascript? Or is it best to create thumbnail as a separate file? 3. How to get

Hello, Iam providing access to many images on a share to windows users from my linux samba over the internet. The problem is that I need thumbnail viewing because of the nature of this library and thumbnails take to much time to load it seems as though it is actually loading the entire image to then display the small thumbnail. Is this true? Also isnt there some kind of caching that can be

I''m trying to modify product images when a user marks a product as "sold" and I am able to modify the original image file successfully, but when I try to reprocess the thumbnails, my ImageMagick modifications don''t stick. Here is what I''ve got going so far: def before_save if self.sold_changed? && self.sold? for photo in self.photos

Howdy. We use the handy file_column plug-in in some of our apps. We have a model with a file field and we upload both images and non-images into this field. It is specified as follows: file_column :file_uri, :magick => {:versions => {:thumbnail => {:size => ''200x''}}} Well, it works great for images but for non-images, the save fails. The root cause is an

howdy! I had the problem that attachment_fu didn''t make a thumbnail, but everything else worked. I read this post http://www.ruby-forum.com/topic/104213 and added a parent_id column. now I get the following error when I trie to add a photo: undefined method `find_or_initialize_by_thumbnail_and_parent_id'' for Photo:Class my code is: class Photo < ActiveRecord::Base

Hey I''m using mini_magick to create some square thumbnail using the following code... image.resize ''x200'' image.resize ''200x<'' image.resize ''50%'' image.gravity ''center'' image.crop ''100x100+0+0''

Seems I''ve seen some discussion in the past about something not right on the server side with ImageMagick when this is happening, but I cant find it now that I''m having the problem. Any advice?

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
