cairoRelCurveTo: cairoRelCurveTo
Description
Relative-coordinate version of cairoCurveTo. 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).Usage
cairoRelCurveTo(cr, dx1, dy1, dx2, dy2, dx3, dy3)
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).
