points, float[][]
4 corner colors
color)

Implements abstract org.apache.pdfbox.pdmodel.graphics.shading.PDMeshBasedShadingType.generatePatch.

Create a patch using control points and 4 corner color values, in Type6ShadingContext, a CoonsPatch is returned; in Type6ShadingContext, a TensorPatch is returned.

public Rectangle2D
getBounds(AffineTransform
the affine transformation
xform, Matrix
the pattern matrix
matrix)

Implements abstract org.apache.pdfbox.pdmodel.graphics.shading.PDMeshBasedShadingType.getBounds.

Calculate a bounding rectangle around the areas of this shading context.

public int
getShadingType()

Overrides org.apache.pdfbox.pdmodel.graphics.shading.PDShadingType4.getShadingType.

This will return the shading type.

public Paint
