Method Cairo.MeshPattern()->curve_to()

Method curve_to

void curve_to(float|int x1, float|int y1, float|int x2, float|int y2, float|int x3, float|int y3)

Description

Adds a cubic Bézier spline to the current patch from the current point to position (x3, y3) in pattern-space coordinates, using (x1, y1) and (x2, y2) as the control points.

If the current patch has no current point before the call to curve_to(), this function will behave as if preceded by a call to move_to(x1, y1).

After this call the current point will be (x3, y3).

Note

If pattern has no current patch or the current patch already has 4 sides, pattern will be put into an error status with a status of STATUS_INVALID_MESH_CONSTRUCTION.

Parameter x1

the X coordinate of the first control point

Parameter y1

the Y coordinate of the first control point

Parameter x2

the X coordinate of the second control point

Parameter y2

the Y coordinate of the second control point

Parameter x3

the X coordinate of the end of the curve

Parameter y3

the Y coordinate of the end of the curve
