similar to: MiniMagick... Core Dump when Reszing Images?

I can''t for the life of me figure this out. Been banging my head on this since the weekend, and can''t see what I''m doing wrong. This code works: image.resize("640x480") image.write(path) I run this and I get the resized file just fine. This doesnt work at all: width = 200 height = 100 dimensions = "#{width}x#{height}"

I have just started using the minimagick gem, as RMagick was giving me the usual problems and eating up too much memory. So far, it works just fine except for one thing. The server allows gives me the following error: mogrify: unable to open module file `/usr/local/lib/ImageMagick-6.2.8/modules-Q16/coders/0.la'': No such file or directory. This happens both locally and on my host.

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/.

Like the subject says, I''ve got a really weird problem. A co-worker added a couple of gems to our rails project. I installed these gems on my machine (a macbook, os x 10.5.6), start the server, and it says it can''t find these gems: ============= Missing these required gems: mini_exiftool = 1.0.1 mini_magick = 1.2.3 You''re running: ruby 1.8.6.114 at

Hi After having updated some GEMS I get `load_missing_constant'': uninitialized constant ActiveSupport::Cache (NameError) on starting the server of a freshly generated rails project. Before, I already had Rails 2.3.2 projects succesfully running, now all of them generate this error. These are my GEMS: actionmailer (2.3.2, 2.2.2, 2.1.2, 2.1.1, 2.1.0) actionpack (2.3.2, 2.2.2, 2.1.2,

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.

Hi. I''m a fairly new mongrel user and have a scenario that I wanted to run by you all, see if anyone''s synapses connect -- mine def. aren''t! I''m running a fairly simple rails app through a mongrel cluster (2 mongrels). This site is consistently sloooow -- memory on the server is regularly paging (and shouldn''t be). ssh-ing in and running top shows

Hi, all, I am having trouble getting R to take pnm images via mogrify i.e. mogrify -resize 320x217 -format pnm *.png However R via pixmap says that it can't read the file. If you have any ideas like a package that can read jpeg files, etc., I would appreciate it. Best wishes, Art Roberts University of Washington

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

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.

My question: On Windows, R's system() command prepends several directories to those in the Windows Path variable. >From ?system The search path for 'command' may be system-dependent: it will include the R 'bin' directory, the working directory and the Windows system directories before 'PATH'. This shadows any executables on the Path that share a

Hi. I''m uploading images using a standard form.

Hi, Mini-Magick breaking. I have installed mini-magick gem.

Hi- I''m suddenly getting this rake error where as before I wasn''t. And nothing''s been changed. As you can see it says something about "load_missing_constant". Is my development environment broken? Can someone please tell me what this error means?: bbgun@echobase:~/RailsProjects/rails_space$ rake test:functionals (in /home/bbgun/RailsProjects/rails_space)

I''ve tried and tried. I couldn''t get freeimage installed. I got mini_magick installed, but everytime I try Mike Clark''s tutorial, I get the error ''Size is not in the list''. I found some people fixed this by putting a sleep statement in their controller, but this didn''t work for me. Any help out there?
