bool OSDL::Video::TwoDimensional::drawBezierCurve	(	Surface &	targetSurface,
		const listPoint2D &	controlPoints,
		Ceylan::Uint16	numberOfSteps,
		Pixels::ColorDefinition	colorDef
	)

Draws a Bezier curve through specified control points, with specified number of steps, with specified color definition, on specified surface.

Parameters:

	targetSurface	the surface where to draw.
	controlPoints	a list of points controlling the shape of the curve, which will start at the location of the first point, end at the location of the last point, but will not necessarily go through intermediate points: they will only "attract" the curve. There must be at least three control points, i.e. at least one intermediate point.
	numberOfSteps	determines how many steps will be computed to interpolate the curve. There must be at least two steps.
	colorDef	the color definition of curve color.

Returns:

false if and only if something went wrong, for example if surface locking failed.

Note:

Locks surface if needed.

Clipping is performed.

Exceptions:

VideoException

if the operation is not supported.

Parameters:

	targetSurface	the surface where to draw.
	controlPoints	a list of points controlling the shape of the curve, which will start at the location of the first point, end at the location of the last point, but will not necessarily go through intermediate points: they will only "attract" the curve. There must be at least three control points, i.e. at least one intermediate point.
	numberOfSteps	determines how many steps will be computed to interpolate the curve. There must be at least two steps.
	red	the red color coordinate of curve color.
	green	the green color coordinate of curve color.

		Coordinate	xCenter,
		Coordinate	yCenter,
		Length	radius,
		Pixels::ColorDefinition	colorDef,
		bool	filled = true,
		bool	blended = true
	)

Draws a circle whose center is (xCenter,yCenter) of specified radius, with specified color definition, on specified surface.

Parameters:

	colorDef	the color definition of the drawing.
	filled	tells whether the circle should be filled (disc).
	blended	tells whether, for each pixel of the disc, the specified color should be blended with the one of the target pixel (if true), or if the disc color should replace the target one, regardless of any blending (if false). Note that only discs may be drawn without being blended: circles are always blended, therefore if filled is false, blended does not matter.

Returns:

false if and only if something went wrong, for example if surface locking failed.

Note:

Locks surface if needed.

Clipping is performed.

A circle will be antialiased if antialias mode is set.

Draws a disc whose center is (xCenter,yCenter), of specified radius (totalRadius), filled with specified color discColorDef, with a ring in it, on its border, i.e.

starting from innerRadius to totalRadius, colored with ringColorDef, on specified surface.

Parameters:

	targetSurface	the surface where to draw.
	xCenter	the abscissa of the center of the disc.
	yCenter	the ordinate of the center of the disc.
	outerRadius	the overall disc radius, including the border ring.

	discColorDef	the inner color of the disc.
	blended	tells whether, for each pixel of the edged disc, the specified color should be blended with the one of the target pixel (if true), or if the specified color should replace the former one, regardless of any blending (if false).

Returns:

false if and only if something went wrong, for example if surface locking failed.

Note:

This method is rather expensive (slow), especially if 'discColorDef' is not fully opaque and if 'blended' is false.

Locks surface if needed, clipping is performed, disc will be antialiased iff antialias mode is set.
