CairoRadialGradient::__construct — The __construct purpose

### 説明

オブジェクト指向型:

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

手続き型:

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().

### パラメータ

`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.
