CairoRadialGradient::__construct — The __construct purpose
説明
オブジェクト指向型:
$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().
