1This gem is a Ruby binding for the libvips image processing library. 2 3Programs that use ruby-vips don't manipulate images directly, instead they 4create pipelines of image processing operations building on a source image. When 5the end of the pipe is connected to a destination, the whole pipeline executes 6at once, streaming the image in parallel from source to destination a section at 7a time. Because ruby-vips is parallel, it's quick, and because it doesn't need 8to keep entire images in memory, it's light. 9
