Subject: [ANN] RMagick 1.11.0



**** RubyGem users on Linux, *BSD, OS X please read the note at the  
end. ****


I've just uploaded RMagick 1.11.0 to RubyForge. This release contains an
important bug fix and some nice new features. Here's the changes:

o   Robert Manni's Image#resize_to_fit resizes an image to fit within
     the specified rectangle while retaining the aspect ratio.

o   The new ImageList#optimize_layers method (available with ImageMagick
     6.2.6) adds several new GIF animation optimization methods.

o   The new Magick.limit_resource method lets you specify an upper  
bound on
     the amount of certain resources (disk space, files, memory) used by
     ImageMagick.

o   I replaced install.rb with the latest version of setup.rb and  
improved
     the gem installation process (bug report from Ryan Davis).

o   You can specify ./configure --disable-htmldoc to suppress creating
     the HTML documentation and executing all the example programs. This
     option is also available to RubyGem users by specifying the --no- 
rdoc
     option on the "gem install" command.

o   The new Image#contrast_stretch_channel method is available with
     ImageMagick 6.2.6.

o   I fixed a possible memory leak that could occur when RMagick  
raised an
     ImageMagickError exception and the program rescued it and  
continued.


RMagick is available as always on RubyForge: http://rubyforge.org/ 
projects/rmagick/


RMagick is an interface to the ImageMagick (www.imagemagick.org) and
GraphicsMagick (www.graphicsmagick.org) image processing libraries. It
supports more than 90 image formats, including GIF, JPEG, PNG. It  
includes
RVG, a 2D drawing API. RMagick has comprehensive HTML documentation  
and comes
with over 175 complete, working example programs.



        *** RubyGem users on Linux, *BSD, OS X please read this. ****

The RMagick 1.11.0 gem is for Linux, *BSD, OS X, Solaris, and other  
*ix-like
systems only. Kaspar is working on a new Win32 gem for RMagick and  
either he
or I will announce it when it's available. If you're using RMagick on MS
Windows you don't need to read any farther. Also, if you plan on  
installing
RMagick with the standard ./configure && make && make install, this  
doesn't
apply to you, either.

The new RubyGem install process in 1.11.0 fixes a mistake in previous  
releases
that caused RMagick to be installed in the "wrong" (to RubyGems)  
directories.
To take advantage of this fix you should completely uninstall any  
earlier
release of RMagick installed using RubyGems before installing RMagick  
1.11.0.

You can uninstall RMagick by deleting all the files yourself, or you  
can use
the script below. If you want to do it yourself, here's what you need  
to do.
(I'm assuming you've got a standard Ruby 1.8.x installation.)

1. Log on to an account that has the permissions necessary to delete
    files from the Ruby library directories.

2. Determine the Ruby "prefix" directory, for example, "/usr/local". If
    you don't know what the prefix directory is, run this command:

		ruby -rrbconfig -e"puts Config::CONFIG['prefix']"

    We'll call the prefix directory $PREFIX.

3. Determine the Ruby "sitearch" directory, for example "powerpc- 
darwin8.3.0".
    If you don't know what the sitearch directory is, run this command:

		ruby -rrbconfig -e"puts Config::CONFIG['sitearch']"
		
    We'll call the sitearch directory $ARCH.

4. Run this command:

	gem uninstall rmagick --all

5. Run these commands:

	rm $PREFIX/lib/ruby/site_ruby/1.8/RMagick.rb
	
	rm -rf $PREFIX/lib/ruby/site_ruby/1.8/rvg
	
	rm $PREFIX/lib/ruby/site_ruby/1.8/$ARCH/RMagick.so
	     (use RMagick.bundle instead of RMagick.so on OS X)
	
	rm -rf $PREFIX/share/RMagick
	
That's it. You're done.


Or instead of doing that you can use this script. Run it from an  
account that
has the appropriate permissions.
