Method: RBPDF#Curve

Defined in:
lib/rbpdf.rb

#Curve(x0, y0, x1, y1, x2, y2, x3, y3, style = '', line_style = nil, fill_color = nil) ⇒ Object Also known as: curve

Draws a Bezier curve. The Bezier curve is a tangent to the line between the control points at either end of the curve.

@param float :x0

Abscissa of start point.

@param float :y0

Ordinate of start point.

@param float :x1

Abscissa of control point 1.

@param float :y1

Ordinate of control point 1.

@param float :x2

Abscissa of control point 2.

@param float :y2

Ordinate of control point 2.

@param float :x3

Abscissa of end point.

@param float :y3

Ordinate of end point.

@param string :style

Style of rendering. See the getPathPaintOperator() function for more information.

@param array :line_style

Line style of curve. Array like for SetLineStyle SetLineStyle. Default value: default line style (empty array).

@param array :fill_color

Fill color. Format: array(GREY) or array(R,G,B) or array(C,M,Y,K). Default value: default color (empty array).
