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

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

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

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

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

Programs with special uncommon file formats (not jpg) often register a shell extension in Explorer that offers thumbnails for these files (since the files otherwise wouldn't have previews). When I trigger in a Wine application (eg. SketchUp) the File Open dialog, I can see previews of the files (skp files) in the preview panel. This means the shell extension does work in Wine. The Shell

Hi, With some help from Quinn_Storm, iXce, maniac103, mikedee and KristianLy :), I've managed to modify switcher.c and make a new plugin: thumbnail. The plugin shows thumbnails of windows when cursor is moved over a task button in taskbar. Screenshot: http://pix.nofrag.com/b0/7a/051d45e25bfffed09eeb9b00e383.jpeg Download:

total rails nuby here. I have a table "thumbnails", hence the model Thumbnail. I''m extending the Thumbnail class with a few constants needed for thumbnail cropping: class Thumbnail < ActiveRecord::Base SOURCE_FILE_PATH = "path/to/source" TARGET_FILE_PATH = "path/to/target" TARGET_WIDTH = 100 TARGET_HEIGHT = 100 end Now, in my controller

Hi! On my page i display one full size image and a list of thumbnails. I''d like to change the full size image with a full size version of a thumbnail, after clicking on one of them. How to write controller action, so it would update the image without reloading the whole page? It''s easy with text, but how to reload an image? -- Posted via http://www.ruby-forum.com/.

Hi, I also posted this question on the IRC #virt channel but have not received any reaction at the moment of posting this message to the mailing list. Since I last turned off my laptop (Dell XPS-15-9570 running Ubuntu 19.04) on Friday 10 May (I had to do it by long power press by the way), I am no longer able to get the display of my VMs: I am getting a black screen, even though I can see it

Im using a customs processor to run ffmpeg on a video to create a thumbnail. So far so good. Except when I do: cmd = "-i #{@file.path} -f flv -s 320x240 ~/Downloads/foobar/q.flv" success = Paperclip.run(''ffmpeg'', cmd) Console is reporting: ffmpeg ''-i /var/folders/uL/uL0bYOOZEZaJH5E+BmDJVE+++TI/-Tmp-/stream, 16824,1.mpeg -f flv -s 320x240

Hi, I''m looking to create a gallery index page of thumbnail images which point to their associated images galleries. Also, I would like to organize the images from left to right and top to bottom. Furthermore, I would like to limit the number of thumbnail images on the page. I guess that I''m needing some type of horizontal looping interface for both the thumbnail index page

I''m creating a simple portfolio site for a painter. I have a painting and an image model with following relationship: Painting has_many :images Image belongs_to :painting On the edit screen the user can edit the Painting data as well as upload pictures for a thumbnails and full size image. The Image model extracts filename, width, and height from the uploaded file, saves those

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

Hi folks. I'm posting this to both the Fedora as well as the CentOS lists in hopes that somewhere, someone can help me figure out what's going on. I have a dual Xeon 3GHz server that's performing rather slow when it comes to disk activities. The machine is configured with a single 160 GiB OS drive (with CentOS 5.0) and 4x500 GiB drives setup in a RAID-5 configuration.

It took me a while to figure this out and I don''t see any wiki pages for attachment_fu so I figure I would just post this here. I didn''t like the way attachment_fu by default creates directories under a given directory for a specific class e.g. item_image/1/img_1.jpg item_image/1/img_1_thumb.jpg item_image/2/img_2.jpg item_image/2/img_2_thumb.jpg item_image/3/img_3.jpg

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/.
