Parameters

page_obj  IntPtr

A handle to a page object. Returned by FPDFPageObj_Create(PageObjectTypes) or FPDFPage_GetObject(IntPtr, Int32)

smoothness  Single

A number in the range 0.0 to 1.0;

The value of this parameter gives the maximum error tolerance, expressed as a fraction of the range of each color component; smaller numbers give smoother color transitions at the expense of more computation and memory use.

The smoothness tolerance controls the quality of smooth shading (type 2 patterns and the sh operator) and thus indirectly controls the rendering performance. Smoothness is the allowable color error between a shading approximated by piecewise linear interpolation and the true value of a (possibly nonlinear) shading function. The error is measured for each color component, and the maximum error is used.The allowable error(or tolerance) is expressed as a fraction of the range of the color component, from 0.0 to 1.0. Thus, a smoothness tolerance of 0.1 represents a tolerance of 10 percent in each color component.
