Bezier_1_3

Syntax:

SI32 pdfBezier_1_3(

const PPDF* IPDF, // Instance pointer

double x1,

// X-Coordinate of the first control point P1

double y1,

// Y-Coordinate of the first control point P1

double x3,

// X-Coordinate of the end point P3

double y3)

// Y-Coordinate of the end point P3

This function paints a Bézier curve with one control point. The second control point P2 coincides

with the final point P3 of the curve. The start point P0 must be set with MoveTo() or any other

painting operator before.

Return values:

If the function succeeds the return value is 1. If the function fails the return value is 0.

Bezier_2_3

Syntax:

SI32 pdfBezier_2_3(

const PPDF* IPDF, // Instance pointer

double x2,

// X-Coordinate of the second control point P2

double y2,

// Y-Coordinate of the second control point P2

double x3,

// X-Coordinate of the end point P3

double y3)

// Y-Coordinate of the end point P3

The third supported Bézier curve type paints also a curve with one control point. In this version the

first control coincides with initial point P0 of the curve. The start point P0 must be set with

MoveTo() or any other painting operator before.

Return values:

If the function succeeds the return value is 1. If the function fails the return value is 0.
