RMagick=bad, ???=good
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,

Attachment_fu ImageScience FreeImage thumbnail quality
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

ImageScience, Mini-Magick and RMagick

Upload image without rmagic
I need a way to upload an image and display it without using any of the plugins that use rmagic. I have used the plugins (file_column, fleximage) which both use rmagic and gave me problems (never got fleximage to work) Thanks in advance - K --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails:

File_column, RMagick, and watermarking
I''m working on a photo gallery and I''m using File_column to handle the uploads of the files and create my thumbnails, but does anyone here have any idea how to have a watermark (opaque text maybe) placed over one of the versions? Any ideas on how to go about this would be great. Even if it''s just straight RMagick code, that would be fine too. Thanks in advance for the

Saving images in shared directory w/ Capistrano/SVN?
Hi all, I''m using Capistrano and SVN to version control and deploy, but I''m not sure what to do about my images directory. I use file_column and RMagick to save images to the disk under a model called "Image", and they''re saved in public/image/... etc. Each time I deploy a new version, my image folder doesn''t exist anymore.

file_column and Thumbnails
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

Using Paperclip::Processor and RMagick to sharpen my thumbnails
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

Image manipulation/resizing server-side?
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/.

limiting options in file_upload
Does anyone know if it''s possible to set constraints to the size & type of file that file_column will accept? I''d like to limit to image files of less than 2MB. If this isn''t possible with file_column, is there a graceful way of getting the controller to handle it? thanks dorian -- -- I do things for love or money

Resizing images and creating thumbnails
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
