Class PdfTensorProductPatchShading
java.lang.Object
com.itextpdf.kernel.pdf.PdfObjectWrapper<PdfDictionary>
com.itextpdf.kernel.pdf.colorspace.shading.AbstractPdfShading
com.itextpdf.kernel.pdf.colorspace.shading.AbstractPdfShadingMesh
com.itextpdf.kernel.pdf.colorspace.shading.AbstractPdfShadingMeshWithFlags
com.itextpdf.kernel.pdf.colorspace.shading.PdfTensorProductPatchShading
The class that extends
AbstractPdfShading
, AbstractPdfShadingMesh
and AbstractPdfShadingMeshWithFlags
classes and is in charge of Shading Dictionary
with Tensor-Product Patch mesh type.
This type of shading is identical to PdfCoonsPatchShading
, 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.

PdfTensorProductPatchShading
Creates the new instance of the class from the existingPdfStream
.- Parameters:

will be created
-
PdfTensorProductPatchShading
public PdfTensorProductPatchShading(PdfColorSpace cs, int bitsPerCoordinate, int bitsPerComponent, int bitsPerFlag, float[] decode) Creates the new instance of the class.- Parameters:
cs
- thePdfColorSpace
object in which colour values shall be expressed. The special Pattern space isn't exceptedbitsPerCoordinate
- the number of bits used to represent each vertex coordinate. The value shall be 1, 2, 4, 8, 12, 16, 24, or 32bitsPerComponent
- the number of bits used to represent each colour component. The value shall be 1, 2, 4, 8, 12, or 16bitsPerFlag
- 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 3decode
- theint[]
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
