MiniMagick Gem
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.

Minimagick and RoR
Posting here is kind of a last resort: has anyone used Minimagick with
Ruby on Rails, and gotten it working correctly? I hate posting a "bug"
problem but I''m not if it''s *my* problem, or a problem with Imagemagick
and RoR 1.0, which I just installed (upgraded from 0.13.1).
Basically, when I try to run the most basic MM command in ROR:

Minimagick issue writing resized file
Hi there
I have a helper method in my Rails app that uses Minimagick as a plugin.
All is fine except for the write step where I attempt to write the
resized file to another directory.
I get the error: "undefined method `to_str'' for #<Array:0x25221e8>"
Here''s my resizing method:

MiniMagick... Core Dump when Reszing Images?
Hi,
I''m using Mini Magick and that attachment_fu plugin to resize images
that the user uploads. Everything looks okay in my code, but I get a
core dump every time an image is uploaded.
The file successfully posts to the application, I can see that the
original file gets copied into the folder correctly. It appears that
it dumps immediately after that. I''m using Mongrel behind

attachment_fu Not Resizing
Hello,
Recently attachment_fu stopped resizing images for me. I''m puzzled
because before today it was resizing them and I don''t know what''s
changed. Here''s my code:

MiniMagick, and processing thumbnails...
I have a requirement that can''t be that outrageous....
I want to be able to upload an image, and have multiple thumbnails be
created for each. Then, I want to post process each image (the main
image plus the thumbnails) to add borders. The trick is that the
borders need to be different for each image. I thought I could use
the after_resize handler, but when I try to add a border to

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

Mini_Magick Problem
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}"

Plugin question
In the rails app I''m making, I dropped MiniMagick into the vendor folder
(vendor/mini_magick). In my controller, when I call:
image = MiniMagick::Image.from_file(path)
...I get a "uninitialized constant MiniMagick" error. From what I can
tell, installing a plugin such as this should be as simple as dropping
it into the vendor folder, then accessing its functions from the

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

delay displaying rmagick resizing of uploaded images
Hi,
I am using rmagick to resize a copy of uploaded images and display the
copy as a thumbnail. Once the upload is processed it redirects the user
to a page that should display the thumbnail to the user. The problem is
that the rmagick resize function seems to keep going in the background
after handing the new images url (and control) back to rails, which then
happily renders the page with

Resize uploaded image file without creating temp file?
Hi,
I need to take a single uploaded image file and save three resized
versions of it, a thumbnail, normal and large version. I was planning on
doing this in my model by having an array of geometry strings and looping
through them, each time saving a new image object resized to the correct
geometry. I know that file column does similar stuff, but I would prefer
to have a separate database row

nfs-ownership
Hi.
I have created some zfs-partitions. First I create the
home/user-partitions. Beneath that I create additional partitions.
Then I have do a chown -R for that user. These partitions are shared
using the sharenfs=on. The owner- and group-id is 1009.
These partitions are visible as the user assigned above. But when I

Good image API for RoR?
Hi, I need a relatively simple image api for the app I''m writing. I
need to copy photos, rename them, and re-size them to put them in a
standard format.
I tried using RMagick/Imagemagick, but the photos would be corrupted on
re-size, so I''m looking for some suggestions.

Creating thumbnail on the fly
I was doing some research about creating thumbnail images on the fly
after an image has been uploaded in a form, but for some reason it''s not
working for me. I''ve downloaded ImageMagick 6.2.5 for Mac but when I run
a test (identify image.gif) it gives me this error:

can't crop images using ImageMagick
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
