ImagickDraw::pathEllipticArcAbsolute — Draws an elliptical arc

说明

ImagickDraw::pathEllipticArcAbsolute ( float $rx , float $ry , float $x_axis_rotation , bool $large_arc_flag , bool $sweep_flag , float $x , float $y ) : bool
Warning

本函数还未编写文档，仅有参数列表。

Draws an elliptical arc from the current point to (x, y) using absolute coordinates. The size and orientation of the ellipse are defined by two radii (rx, ry) and an xAxisRotation, which indicates how the ellipse as a whole is rotated relative to the current coordinate system. The center (cx, cy) of the ellipse is calculated automatically to satisfy the constraints imposed by the other parameters. largeArcFlag and sweepFlag contribute to the automatic calculations and help determine how the arc is drawn. If largeArcFlag is TRUE then draw the larger of the available arcs. If sweepFlag is true, then draw the arc matching a clock-wise rotation.
