)이 함수는 현재 문서화 되어있지 않습니다; 인수 목록만을 제공합니다.
Draws a quadratic Bezier curve from the current point to (x,y) using (x1,y1) as the control point using absolute coordinates. At the end of the command, the new current point becomes the final (x,y) coordinate pair used in the polybezier.
x1x coordinate of the control point
y1y coordinate of the control point
xx coordinate of the end point
yy coordinate of the end point

Example #1 ImagickDraw::pathCurveToQuadraticBezierAbsolute()
<?php

$draw->setFontSize(72);
$draw->pathStart();
$draw->pathMoveToAbsolute(50,250);
// This specifies a quadratic bezier curve with the current position as the start
// point, the control point is the first two params, and the end point is the last two params.
$draw->pathCurveToQuadraticBezierAbsolute(
150,50,
250,250

// This specifies a quadratic bezier curve with the current position as the start
// point, the control point is mirrored from the previous curves control point
// and the end point is defined by the x, y values.
$draw->pathCurveToQuadraticBezierSmoothAbsolute(
450,250
);
// This specifies a quadratic bezier curve with the current position as the start
// point, the control point is mirrored from the previous curves control point
// and the end point is defined relative from the current position by the x, y values.
