ImageMagick - NoDecodeDelegate?

Hello-

I just switched from Instant Rails and am trying to get a simple RMagick example to run but am getting the following error:

C:/BITNAM_{1/ruby/lib/ruby/gems/1.8/gems/rmagick-1.15.9-win32/lib/RMagick.rb:1659:in `read’: NoDecodeDelegateForThisImage
Format `logo.jpg’ (Magick::ImageMagickError) from C:/BITNAM}1/ruby/lib/ruby/gems/1.8/gems/rmagick-1.15.9-win32/lib/RMagick.rb:1659:in `initialize’ from C:/BITNAM<sub>1/ruby/lib/ruby/gems/1.8/gems/rmagick-1.15.9-win32/lib/RMagick.rb:1658:in `each’ from C:/BITNAM</sub>1/ruby/lib/ruby/gems/1.8/gems/rmagick-1.15.9-win32/lib/RMagick.rb:1658:in `initialize’ from imagePlay.rb:4:in `new’ from imagePlay.rb:4

The example I am trying to run can be found here (example #1):
http://www.imagemagick.org/RMagick/doc/usage.html

Can anyone help me here?

Thanks!

So, as a side question to this topic….Do you have to do any configuration to get ImageMagick to work properly?

Hey Pete,

Which version of Rubystack are you using?
The first version did have problems with imagick/rmagick, which were solved in RubyStack 1.0-beta-2.

In case you are using the latest version, could you post the output when executing “set” in command line? (the MAGICK_* related lines should be enough), especially the MAGICK_CODER_MODULE_PATH variable.

Cheers,

Pieter

I am using the latest version, below is the output from “set”. See anything wrong here?

MAGICK_CODER_MODULE_PATH=C:\PROGRA_1\BITNAM1\imagemagick\modules\coders
Path=C:\BITNAM_{1\ruby\bin;C:\BITNAM}1\mysql\bin;C:\BITNAM_{1\subversion\bin;C:\BITNAM}1\imagemagick;C:\Tcl\bin;C:\Perl\bi

QTJAVA=C:\Program Files\Java\jre1.6.0_03\lib\ext\QTJava.zip
RUBYOPT=rubygems

yes :)

Just edit the file C:\BITNAM~1\scripts\load_path.bat and substitute this:

MAGICK_CODER_MODULE_PATH=C:\PROGRA~1\BITNAM~1\imagemagick\modules\coders

for this:

MAGICK_CODER_MODULE_PATH=C:\BITNAM~1\imagemagick\modules\coders

and everything should work now. We we’ll solve this issue in future releases, thank you for helping us.

Thanks.

I thought I could edit this path in the system properties but I don’t see it in there. Where do I update this path?

As Manuel said, the path should be editable via C:\BITNAM~1\scripts\load_path.bat
Close the Ruby console and open it again and it should work.

I guess it help for me to read the whole post. :)

That worked, thanks very much!

You’re welcome.
I’m glad it worked!

Ciao
