Abstract
A method and apparatus for creating a blend from one arbitrary edge ( ) to a second arbitrary edge ( ) in a computer graphic image creation is disclosed. A color along each of the edges ( ) is determined. A parametric equation is then formed for a color of each pixel ( ) within the area bounded by the edges ( ), and the parametric equation is solved to derive a color for each of the pixels ( ). In another aspect, after determining the color along each edge ( ), each of the edges ( ) is vectorised into corresponding line segments ( to ). Pairs of the line segments ( to ) are then matched to form polygons ( ) having a defined color at each of vertices, A color is then determined for each pixel of the polygon ( ) from the defined colors of the vertices.
