org.apache.fop.pdf.PDFShading
public class PDFShading
class representing a PDF Smooth Shading object. PDF Functions represent parameterized mathematical formulas and sampled representations with arbitrary resolution. Functions are used in two areas: device-dependent rasterization information for halftoning and transfer functions, and color specification for smooth shading (a PDF 1.3 feature). All PDF Functions have a shadingType (0,2,3, or 4), a Domain, and a Range.

name - the name of the shading pattern. Can be anything
without spaces. "Shading1" or "Sh1" are good examples.public java.lang.String toPDFString()
toPDFString in class PDFObjectprotected boolean contentEquals(PDFObject obj)
Note: This function has a contract which is less binding than
Object.equals(Object). Whereas equals would require all values to be
identical, this method is not required to check everything. In the case
of PDFObjects, this means that the overriding function does not have to
check for PDFObject.getObjectID().
contentEquals in class PDFObjectobj - object to compare to.
