CairoRadialGradient::__construct — The __construct purpose
Description
Object oriented style:
$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.
