Draws an elliptical arc from the current point to (x, y). The size and orientation of the ellipse are defined by two radii (rx, ry) and an x-axis-rotation, which indicates how the ellipse as a whole is rotated relative to the current coordinate system. The center (cx, cy) of the ellipse is calculated automatically to satisfy the constraints imposed by the other parameters. For a given radii pair, there are two ellipses that could connect two random points. large-arc-flag and sweep-flag contribute to the automatic calculations and help determine how the arc is drawn.

Set current source to the solid color defined by the rgb components.

+

Set current source to the solid opaque color defined by the rgb components. The color components are floating point numbers in the range 0 to 1.

+

The default source pattern is opaque black, (that is, it is equivalent to vkvg_set_source_rgb(ctx,0,0,0)).
