Abstract
In order to preserve the discontinuities of an actual gamut surface and/or the discontinuities of its curvature, notably through a smoothing operation, in this method, when at least a vertex of any elementary polygon, the network of which represents an actual gamut boundary, belongs either to a line or a point of discontinuity of this actual gamut boundary, either to a line or a point of discontinuity of curvature of said actual gamut boundary, or both, metadata related to this belongings are added to the definition of the elementary polygons.
