Enclosing class:
PdfShading
public static class PdfShading.TensorProductPatchMesh extends PdfShading
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.

  • Constructor Details

    • TensorProductPatchMesh

      protected TensorProductPatchMesh (PdfStream pdfStream)
      Creates the new instance of the class from the existing PdfStream.
      Parameters:
      pdfStream - from which this PdfShading.TensorProductPatchMesh will be created

    • TensorProductPatchMesh

      public TensorProductPatchMesh (PdfColorSpace cs, int bitsPerCoordinate, int bitsPerComponent, int bitsPerFlag, float[] decode)
      Creates the new instance of the class.
      Parameters:
      cs - the PdfColorSpace object in which colour values shall be expressed. The special Pattern space isn't excepted.
      bitsPerCoordinate - the number of bits used to represent each vertex coordinate. The value shall be 1, 2, 4, 8, 12, 16, 24, or 32.
      bitsPerComponent - the number of bits used to represent each colour component. The value shall be 1, 2, 4, 8, 12, or 16.
      bitsPerFlag - 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 - 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.
