The first control point is assumed to be the reflection of the second control point on the previous command relative to the current point. (If there is no previous command or if the previous command was not an DrawPathCurveToAbsolute, DrawPathCurveToRelative, DrawPathCurveToSmoothAbsolute or DrawPathCurveToSmoothRelative, assume the first control point is coincident with the current point.) (x2,y2) is the second control point (i.e., the control point at the end of the curve). At the end of the command, the new current point becomes the final (x,y) coordinate pair used in the polybezier. </p> </div> <div class="refsect1 parameters"> <h3 class="title">Parameters</h3> <p class="para"> <dl> <dt> <span class="term"><i><tt class="parameter">x2</tt></i></span> <dd> <p class="para"> x coordinate of the second control point </p> </dd> </dt> <dt> <span class="term"><i><tt class="parameter">y2</tt></i></span> <dd> <p class="para"> y coordinate of the second control point </p> </dd> </dt> <dt> <span class="term"><i><tt class="parameter">x</tt></i></span> <dd> <p class="para"> x coordinate of the ending point </p> </dd> </dt> <dt> <span class="term"><i><tt class="parameter">y</tt></i></span> <dd> <p class="para"> y coordinate of the ending point </p> </dd> </dt> </dl> </p> </div> <div class="refsect1 returnvalues"> <h3 class="title">Return Values</h3> <p class="para"> No value is returned. </p> </div></div><hr /><div style="text-align: center;"> <div class="prev" style="text-align: left; float: left;"><a href="function.imagickdraw-pathcurvetosmoothabsolute.html">ImagickDraw::pathCurveToSmoothAbsolute</a></div> <div class="next" style="text-align: right; float: right;"><a href="function.imagickdraw-pathellipticarcabsolute.html">ImagickDraw::pathEllipticArcAbsolute</a></div> <div class="up"><a href="class.imagickdraw.html">The ImagickDraw class</a></div> <div class="home"><a href="index.html">PHP Manual</a></div></div></body></html>⌨️ 快捷键说明
