# GenericImage
#
# Default content datastreams: content, original (optional), max, thumbnail, screen
#
# Sample Usages:
# From file:
# my_image = File.new("#{Rails.root}/spec/fixtures/image.tiff")
# gi = GenericImage.new
# gi.content=my_image
# gi.save
#
# From url:
# my_image = "http://example.com/path/to/some/image.jpeg"
# gi = HydraImage.new
# gi.content=my_image
#
# From binary string:
# my_image = File.open("#{Rails.root}/spec/fixtures/image.tiff")
# my_blob = my_image.read
# gi = HydraImage.new
# gi.content={ :blob=> my_blob, :extension => ".tiff" }
#
# To create the derived images:
# gi.derive_all # creates max, screen and thumbnail from content datastream
# gi.derive_max
# gi.derive_screen
# gi.derive_thumbnail
#
# To get the content of a default datastream:
# max = gi.max
# screen = gi.screen
# thumbnail = gi.thumbnail
#
# To determine if a particular datastream exists for an image:
# gi.has_content?
# gi.has_original?
# gi.has_max?
# gi.has_screen?
# gi.has_thumbnail?
