ImageMagick and resizing bitmaps

How to resize bitmap using ‘magick.rb’?
I have this code:

image = Magick::Image.new ARGV[0]
image.set “size”=>"50x500"
image.write(“filename”=>“out.jpg”)

but it doesn’t work. ‘out.jpg’ is exact copy of source image.

Hmmm…I haven’t seen the original post, but the code snippet looks like
it might be for the RubyMagick package that predated RMagick. Certainly
RMagick doesn’t have a set method.
