cairo_rel_curve_to

Relative-coordinate version of cairo_curve_to(). All offsets are relative to the current point. Adds a cubic Bézier spline to the path from the current point to a point offset from the current point by (dx3, dy3), using points offset by (dx1, dy1) and (dx2, dy2) as the control points. After this call the current point will be offset by (dx3, dy3).

cairo_rel_curve_to(cr, dx1, dy1, dx2, dy2, dx3, dy3)

Arguments

cr	[cairo_t *] a cairo context
dx1	[double] the X offset to the first control point
dy1	[double] the Y offset to the first control point
dx2	[double] the X offset to the second control point
dy2	[double] the Y offset to the second control point
dx3	[double] the X offset to the end of the curve
dy3	[double] the Y offset to the end of the curve

Details

Given a current point of (x, y), cairo_rel_curve_to(cr, dx1, dy1, dx2, dy2, dx3, dy3) is logically equivalent to cairo_curve_to(cr, x+dx1, y+dy1, x+dx2, y+dy2, x+dx3, y+dy3).

It is an error to call this function with no current point. Doing so will cause cr to shutdown with a status of %CAIRO_STATUS_NO_CURRENT_POINT.

Since: 1.0

C function prototype: void cairo_rel_curve_to (cairo_t *cr, double dx1, double dy1, double dx2, double dy2, double dx3, double dy3)
