public static class PdfShading.LatticeFormGouraudShadedTriangleMesh extends PdfShading
The class that extendsPdfShading
class and is in charge of Shading Dictionary with lattice-form Gouraud-shaded triangle mesh type. This type is similar toPdfShading.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 toPdfShading.FreeFormGouraudShadedTriangleMesh
, except there is no edge flag.
