Output Tab Settings

Use the Global Composite settings to specify how all masks, combined together using their individual modes, affect the alpha channel for the selected input source image.

Select:	To:
Comp	Choose which compositing mode will be used --see Global Composite Operators.
Correlation	Specify how input mattes are correlated. This can be used to improve the quality of the composite in special cases. For example, if you composite two mattes that share a good portion of their outline, you should indicate if they are Adjacent or Superposed. By default, the correlation mode is None, assuming that normally, the input mattes are not correlated.
Crop	Change the size of an image--see Crop Tool.
User Settings	Store initial mask parameters that can be reused during the rotoscoping process--see User Settings.
