ImagickDraw::pathCurveToQuadraticBezierAbsolute

(PECL imagick 2.0.0)

ImagickDraw::pathCurveToQuadraticBezierAbsoluteDraws a quadratic Bezier curve

Descrição

bool ImagickDraw::pathCurveToQuadraticBezierAbsolute ( float $x1 , float $y1 , float $x , float $y )
Aviso

Esta função não está documentada; somente a lista de argumentos está disponível.

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.

Parâmetros

x1

x coordinate of the control point

y1

y coordinate of the control point

x

x coordinate of the end point

y

y coordinate of the end point

Valor Retornado

Não há valor retornado.
