(PECL imagick 2, PECL imagick 3)

ImagickDraw::pathCurveToSmoothRelative — Draws a cubic Bezier curve

    float $x2,
    float $y2,
    float $x,
    float $y
): bool
警告

本函數還未編寫(xiě)文檔，僅有參數列表。

Draws a cubic Bezier curve from the current point to (x,y) using relative coordinates. 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.

參數

x2

x coordinate of the second control point

y2

y coordinate of the second control point

x

x coordinate of the ending point

y

y coordinate of the ending point
