#make_tmpname(prefix_suffix, n) ⇒ Object

Due to how ImageMagick handles its image format conversion and how Tempfile handles its naming scheme, it is necessary to override how Tempfile makes # its names so as to allow for file extensions. Idea taken from the comments on this blog post: marsorange.com/archives/of-mogrify-ruby-tempfile-dynamic-class-definitions

This is Ruby 1.9.3’s implementation.
