Abstract
Methods and apparatus operable to create transfer or blending functions defining blending modes for image processing. The identity of a first transfer mode function T1 and of a second transfer mode function T2 are obtained in a graphical image process system, and a new transfer mode is dynamically defined having a new transfer mode function T defined as a mathematical combination of the first transfer mode function and the second transfer mode function. An interpolation value beta may be obtained and the new transfer mode function may be an interpolated function T=T1×beta+T2×(1−beta). A third transfer mode function T3 may be obtained and the new transfer mode function may be a composite function T=T3(T1, T2). Beta may be a position-depended value of a solidity mask.
