Generalized primitives for smooth coloring of vector graphics artwork in constant time

摘要

Diffusion coloring of vector graphics artwork is performed in constant time based on the number of color channels in a specified color space. In some examples, a method may include establishing color handles within an artwork, and defining mesh vertices distributed throughout the artwork. The method may also include determining a resultant color at each mesh vertex by solving the Laplacian equation for each of i color channels in a color space, wherein solving the Laplacian equation for each of the i color channels produces a corresponding i color values that collectively define the resultant color. A color for a pixel in the artwork can be determined by interpolating between the resultant colors at the mesh vertices.
