Circle() [1/4]

void Gorgon::CGI::Circle	(	Containers::Image &	target,
		P_	location,
		Float	radius,
		F_	fill = SolidFill<>(Graphics::Color::Black)
	)

Draws a filled circle with the specified radius to the given target.

This function is very fast but is not very accurate. Any S_ value > 1 will enable AA.

References basic_Image< T_ >::GetHeight(), basic_Image< T_ >::GetRGBAAt(), basic_Image< T_ >::GetWidth(), and basic_Image< T_ >::SetRGBAAt().

Circle() [2/4]

void Gorgon::CGI::Circle	(	Containers::Image &	target,
		P_	location,
		Float	radius,
		Float	border,
		F_	fill = SolidFill<>(Graphics::Color::Black)
	)

Draws a circle outline with the specified radius to the given target.

This function is very fast but is not very accurate. Radius is the inner radius of the circle. Any S_ value > 1 will enable AA.

LinesToPolygons()

std::vector<Geometry::PointList<P_> > Gorgon::CGI::LinesToPolygons	(	const Geometry::PointList< P_ > &	p,
		StrokeSettings	settings = 1.0
	)

Returns the polygon to draw a list of lines.

Polyfill() [1/4]

void Gorgon::CGI::Polyfill	(	Containers::Image &	target,
		const Geometry::PointList< P_ > &	p,
		F_	fill = SolidFill<>{Graphics::Color::Black}
	)

This function fills the given point list as a polygon.

List is treated as closed where last pixel connects to the first. S_ is the number of subdivision for subpixel accuracy.

References Gorgon::Graphics::Color::Black.

Polyfill() [2/4]

void Gorgon::CGI::Polyfill	(	Containers::Image &	target,
		const std::vector< Geometry::PointList< P_ >> &	p,
		F_	fill = SolidFill<>{Graphics::Color::Black}
	)

This function fills the given point list as a polygon.

List is treated as closed where last pixel connects to the first. S_ is the number of subdivision for subpixel accuracy. If subpixelonly is true, the segment where fully set pixels are determined is skipped. When drawing very thin polygon such as lines, setting this parameters can improve speed. S_ should be a power of two for this algorithm to work properly. W_ is winding, 1 is odd, 0 is non-zero.
