cairoCurveTo: cairoCurveTo
Description
Adds a cubic Bzier 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
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
).
