CairoRadialGradient::__construct

The __construct purpose

Description

Object oriented style:

public CairoRadialGradient::__construct ( float $x0 , float $y0 , float $r0 , float $x1 , float $y1 , float $r1 )

Procedural style:

Creates a new radial gradient CairoPattern between the two circles defined by (x0, y0, r0) and (x1, y1, r1). Before using the gradient pattern, a number of color stops should be defined using CairoRadialGradient::addColorStopRgb or CairoRadialGradient::addColorStopRgba.

Note: The coordinates here are in pattern space. For a new pattern, pattern space is identical to user space, but the relationship between the spaces can be changed with CairoRadialGradient::setMatrix.

Parameters

x0

x coordinate for the center of the start circle.

y0

y coordinate for the center of the start circle.

r0

radius of the start circle.

x1

x coordinate for the center of the end circle.

y1

y coordinate for the center of the end circle.

r1

radius of the end circle.
