Detailed Description

The class that extends PdfShading class and is in charge of Shading Dictionary with lattice-form Gouraud-shaded triangle mesh type.

The class that extends PdfShading class and is in charge of Shading Dictionary with lattice-form Gouraud-shaded triangle mesh type. This type is similar to FreeFormGouraudShadedTriangleMesh but instead of using free-form geometry, the vertices are arranged in a pseudorectangular lattice, which is topologically equivalent to a rectangular grid. The vertices are organized into rows, which need not be geometrically linear. The verticals data in stream is similar to FreeFormGouraudShadedTriangleMesh , except there is no edge flag.
