Fill transfer modes: Algorithms that determine the resulting fill color of a graphic drawn into an image when pixels of one color overlay pixels of another color.
Frame transfer modes: Algorithms that determine the resulting frame color of a graphic drawn into an image when pixels of one color overlay pixels of another color.
Image transfer modes: Algorithms that determine the resulting color of the image when pixels of one color overlay pixels of another color.
Image Sampling: Investigating the status of an image prior to drawing it when the image is enlarged (interpolated) creating pixel gaps or shrunk (decimated) compressing the pixel information.
