hi, is it possible to resize animated gifs with file_column? if i upload an animated gif file with file_column than the animation no longer exists... -- Posted via http://www.ruby-forum.com/.
Hi folks,
I just started getting this error all of a sudden (command line snippet):
vmac:~/workspace/eir vince$ ruby -v
ruby 1.8.2 (2004-12-25) [powerpc-darwin8.0]
vmac:~/workspace/eir vince$ rails -v
Rails 1.0.0
vmac:~/workspace/eir vince$ gem -v
0.8.11
vmac:~/workspace/eir vince$ ./script/server
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in
`require__'': No
such file to load -- initializer (LoadError)
from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in
`require''
from ./script/../config/boot.rb:16
from ./script/server:2:in `require''
from ./script/server:2
vmac:~/workspace/eir vince$
Is anybody else having the same issue? Any clues as to what may be wrong?
I did nothing to my environment, but the problem started after Mac OS X
notified me that updates were available and I started them in the
back-ground.

These instructions seem to have fixed the problem: http://www.tonyarnold.com/articles/2005/08/10/rolling-with-ruby-on-rails-on- mac-os-x-tiger-for-beginners On 4/7/06 11:46 AM, "Vince Puzzella" <vpuz@rogers.com> wrote:> Hi folks, > > I just started getting this error all of a sudden (command line snippet): > > vmac:~/workspace/eir vince$ ruby -v > ruby 1.8.2 (2004-12-25) [powerpc-darwin8.0] > vmac:~/workspace/eir vince$ rails -v > Rails 1.0.0 > vmac:~/workspace/eir vince$ gem -v > 0.8.11 > vmac:~/workspace/eir vince$ ./script/server > /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in `require__'': No > such file to load -- initializer (LoadError) > from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in > `require'' > from ./script/../config/boot.rb:16 > from ./script/server:2:in `require'' > from ./script/server:2 > vmac:~/workspace/eir vince$ > > Is anybody else having the same issue?

Yes, but you may have to tinker around with RMagick/imagemagick. I would *guess* that your image is being split into its component frames as its being resized, and the command to merge the frames back into an animation is not being given. So that''s a bug you''ll have to get past, but then it should work. -Kyle On 4/7/06, Trung Tran <trung_tran@gmx.de> wrote:> hi, > > is it possible to resize animated gifs with file_column? > if i upload an animated gif file with file_column than the animation no > longer exists... > > -- > Posted via http://www.ruby-forum.com/. > _______________________________________________ > Rails mailing list > Rails@lists.rubyonrails.org > http://lists.rubyonrails.org/mailman/listinfo/rails >
