Factor 1.0 always returns a copy of the original image, lower factors mean less color (brightness, contrast, etc), and higher values more. There are no restrictions on this value. :rtype: :py:class:`~PIL.Image.Image` )rZblendÚ degenerateÚimage)ÚselfÚfactor©r úE/var/www/dbchiro/venv/lib/python3.4/site-packages/PIL/ImageEnhance.pyÚenhances z_Enhance.enhanceN)Ú__name__Ú __module__Ú __qualname__r r r r r rs rc@s"eZdZdZdd„ZdS)ÚColoraAdjust image color balance. This class can be used to adjust the colour balance of an image, in a manner similar to the controls on a colour TV set. An enhancement factor of 0.0 gives a black and white image. A factor of 1.0 gives the original image. cCsU||_d|_d|jƒkr0d|_n|j|jƒj|jƒ|_dS)NÚLÚAZLA)rZintermediate_modeÚgetbandsÚconvertÚmoder)rrr r r Ú__init__0s    zColor.__init__N)r rrÚ__doc__rr r r r r(s rc@s"eZdZdZdd„ZdS)ÚContrastzòAdjust image contrast.
