I’m getting the crazy error “undefined method `resize\_to\_fit’ for  
#Magick::Image:0x41b74904”

I have RMagick on dreamhost, but no resize\_to\_fit method? Am I missing  
something?

You may be missing a sufficiently recent version of RMagick. The  
resize\_to\_fit method was added in version 1.11.0. What version of  
RMagick is installed? Try this:

ruby -r RMagick -e"puts Magick::Long\_version"

If the version is older than 1.11.0, you can add it yourself. The  
Image#resize\_to\_fit method is extremely simple to write. The code for it  
in RMagick.rb is this:

```
def resize_to_fit(cols, rows)
    change_geometry(Geometry.new(cols, rows)) do |ncols, nrows|
        resize(ncols, nrows)
    end
end
```

Indeed on my host ([clamato.dreamhost.com](http://clamato.dreamhost.com)) I have Rmagick 1.6.0, a 2004  
build.  
This is RMagick 1.6.0 ($Date: 2004/08/18 23:22:36 $) Copyright (C) 2004

This is my first public rails website and I’m still learning. Your  
solution was perfect. I just added this on top of my model.rb. It needed  
a small modification, so I’m posting this here, maybe to help another  
newbie.

# quick hack for dreamhost for an old version of RMagick

class Magick::Image  
def resize\_to\_fit!(cols, rows)  
change\_geometry(Magick::Geometry.new(cols, rows)) do |ncols, nrows|  
resize!(ncols, nrows)  
end  
end

def resize\_to\_fit(cols, rows)  
change\_geometry(Magick::Geometry.new(cols, rows)) do |ncols, nrows|  
resize(ncols, nrows)  
end  
end  
end
