public static class PdfShading.TensorProductPatchMesh extends PdfShading
The class that extendsPdfShading
class and is in charge of Shading Dictionary with Tensor-Product Patch mesh type. This type of shading is identical toPdfShading.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.
