Description Usage Arguments Details Author(s)

View source: R/cairoFuncs.R

Description

Adds a cubic B<U+00E9>zier spline to the path from the current point to position (x3, y3) in user-space coordinates, using (x1, y1) and (x2, y2) as the control points. After this call the current point will be (x3, y3).

Usage

1
cairoCurveTo(cr, x1, y1, x2, y2, x3, y3)

Arguments

cr

[Cairo] a cairo context

x1

[numeric] the X coordinate of the first control point

y1

[numeric] the Y coordinate of the first control point

x2

[numeric] the X coordinate of the second control point

y2

[numeric] the Y coordinate of the second control point

x3

[numeric] the X coordinate of the end of the curve

y3

[numeric] the Y coordinate of the end of the curve

Details

If there is no current point before the call to cairoCurveTo this function will behave as if preceded by a call to cairo_move_to(cr, x1, y1).
