Remarks

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 PdfShading.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 PdfShading.FreeFormGouraudShadedTriangleMesh , except there is no edge flag.

Constructors

LatticeFormGouraudShadedTriangleMesh(PdfColorSpace, int, int, int, float[])

Creates the new instance of the class.

public LatticeFormGouraudShadedTriangleMesh(PdfColorSpace cs, int bitsPerCoordinate, int bitsPerComponent, int verticesPerRow, float[] decode)

Parameters

cs PdfColorSpace

the PdfColorSpace object in which colour values shall be expressed. The special Pattern space isn't excepted.

bitsPerCoordinate int

the number of bits used to represent each vertex coordinate. The value shall be 1, 2, 4, 8, 12, 16, 24, or 32.

bitsPerComponent int

the number of bits used to represent each colour component. The value shall be 1, 2, 4, 8, 12, or 16.

verticesPerRow int

the number of vertices in each row of the lattice (shall be > 1). The number of rows need not be specified.

decode float[]

the int[] of numbers specifying how to map vertex coordinates and colour components into the appropriate ranges of values. The ranges shall be specified as follows: [x_min x_max y_min y_max c1_min c1_max … cn_min cn_max]. Only one pair of color values shall be specified if a Function entry is present.
