cairoCurveTo

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

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).
