Remarks

The class that extends PdfShading class and is in charge of Shading Dictionary with Tensor-Product Patch mesh type. This type of shading is identical to PdfShading.CoonsPatchMesh , except that it's based on a bicubic tensor-product patch defined by 16 control points. For the format of data stream, that defines patches, see ISO-320001 Table 86.

Constructors

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

Creates the new instance of the class.

public TensorProductPatchMesh(PdfColorSpace cs, int bitsPerCoordinate, int bitsPerComponent, int bitsPerFlag, 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.

bitsPerFlag int

the number of bits used to represent the edge flag for each vertex. The value of BitsPerFlag shall be 2, 4, or 8, but only the least significant 2 bits in each flag value shall be used. The value for the edge flag shall be 0, 1, 2 or 3.

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.

TensorProductPatchMesh(PdfColorSpace, int, int, int, PdfArray)

Creates the new instance of the class.

public TensorProductPatchMesh(PdfColorSpace cs, int bitsPerCoordinate, int bitsPerComponent, int bitsPerFlag, PdfArray 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.

bitsPerFlag int

the number of bits used to represent the edge flag for each vertex. The value of BitsPerFlag shall be 2, 4, or 8, but only the least significant 2 bits in each flag value shall be used. The value for the edge flag shall be 0, 1, 2 or 3.
