				Scale Node

				Scale node


				This node scales the size of an image. Scaling can be either absolute or relative.
				If Absolute toggle is on, you can define the size of an image by using real pixel values.
				In relative mode percents are used.

				For instance X: 0.50 and Y: 0.
				50 would produce image which width and height would be half of what they used to be.
				When expanding an image greatly,
				you might want to blur it somewhat to remove the square corners that might result.
				Unless of course you want that effect; in which case, ignore what I just said.

				Use this node to match image sizes. Most nodes produce an image that is the same size as the
				image input into their top image socket. So,
				if you want to uniformly combine two images of different size,
				you must scale the second to match the resolution of the first.


				Flip Node
				=========

				.. figure:: /images/Manual-Compositing_Nodes-Flip.jpg

				Flip node


				This node flips an image at defined axis that can be either X or Y.
				Also flipping can be done on both X and Y axis' simultaneously.

				You can use this node to just flip or use it as a part of mirror setting.
				Mix half of the image to be mirrored with its flipped version to produce mirrored image.
