Problem Installing RMagick
Okay, so I am setting up a brand new Macbook and can''t seem to get
RMagick or ImageMagick to install with Darwin Ports. Can anyone give
me some insight as to why this may be failing? I get the same error
when I do a "sudo port install imagemagick".
Thanks!

Rmagick file conversion
I am using rmagick to convert files stored as a tiff to either pdf or
jpg for display to the user. A snippet of test code from the controller
follows. It works OK. ( it does need a sanitizer )
require RMagick
def pdf
@sdoc = Sdoc.find(params[:id])
@fname = ''/var/www/images/'' + @sdoc.fname
@nf = Magick::ImageList.new(@fname)

File_column crashing WEBrick when using :magick options
I''m trying to use file_column in an app I''m writing. Simple file uploads
are working fine.
However, when I try and use the :magick options to make resized

This is the Media model:

resize images
Hi,
I am looking for the best solution to resize images to fit within a
certain area. The images will only be made smaller if they will not
fit within a fixed size area. It is important to maintain the same
proportions.
This ImageMagick extension looks promising:

However, I believe it may be overkill for just resizing images
sometimes. I have also seen a

ImageMagick/Rmagick replacement?
Hi, everyone!
I have been recently hit by ImageMagick/Rmagick memory leak issues.
I know I can lesson the problem by manually starting up GC each time
I use Rmagick library but ImageMagick seems to use way too much
memory nevertheless. (on shared hosting setup anyway)
Is there a decent replacement for ImageMagick library? I used to
think ImageMagick was quite efficient because its

Frustrating "require" problems with RMagick
I am using RMagick in my app and am having problems in deployment. The
deployment machine (Fedora Core 5) can''t find RMagick unless I change
the "require" syntax from that used on the dev machine (OS X). And the
dev machine doesn''t like the syntax that works on the deployment server!

RMagick problems
I read the 13th recipe in the book "Rails Recipes" from Chad Fowler. I

So, I create a controller with script/generate. In a method, which I

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.

Rmagick not handling GIF files properly...

when uploaded via file_column. I can upload JPG files just fine.
Originally I had installed ImageMagick via Debian''s apt-get and built the
rmagick gem using "gem install rmagick". This wasn''t working so I

Rails, Mongrel and Rmagick
i have a rails app with a form that allows uploading an image file. I take
the image file and read it into rmagick to verify that it''s an image. For
some reason I can''t catch an exception thrown by rmagick inside the app.
After an invalid image file is uploaded the process just hangs. I have to
kill mongrel and restart to use the app again.
