Member Function Documentation

bool Gosu::Graphics::begin

(

Color

clearWithColor = Color::BLACK

)

Prepares the graphics object for drawing.

Nothing must be drawn without calling begin.

void Gosu::Graphics::beginClipping	(	int	x,
		int	y,
		unsigned	width,
		unsigned	height
	)

Enables clipping to a specified rectangle.

void Gosu::Graphics::beginGL

(

)

Finishes all pending Gosu drawing operations and executes the following OpenGL code in a clean environment.

void Gosu::Graphics::beginRecording

(

)

Starts recording a macro. Cannot be nested.

std::auto_ptr<ImageData> Gosu::Graphics::createImage	(	const Bitmap &	src,
		unsigned	srcX,
		unsigned	srcY,
		unsigned	srcWidth,
		unsigned	srcHeight,
		unsigned	borderFlags
	)

Turns a portion of a bitmap into something that can be drawn on this graphics object.

void Gosu::Graphics::drawLine	(	double	x1,
		double	y1,
		Color	c1,
		double	x2,
		double	y2,
		Color	c2,
		ZPos	z,
		AlphaMode	mode = amDefault
	)

Draws a line from one point to another (last pixel exclusive).

void Gosu::Graphics::drawQuad	(	double	x1,
		double	y1,
		Color	c1,
		double	x2,
		double	y2,
		Color	c2,
		double	x3,
		double	y3,
		Color	c3,
		double	x4,
		double	y4,
		Color	c4,
		ZPos	z,
		AlphaMode	mode = amDefault
	)

void Gosu::Graphics::drawTriangle	(	double	x1,
		double	y1,
		Color	c1,
		double	x2,
		double	y2,
		Color	c2,
		double	x3,
		double	y3,
		Color	c3,
		ZPos	z,
		AlphaMode	mode = amDefault
	)

void Gosu::Graphics::end

(

)

Every call to begin must have a matching call to end.

void Gosu::Graphics::endClipping

(

)

Disables clipping.

void Gosu::Graphics::endGL

(

)

Resets Gosu into its default rendering state.

std::auto_ptr<Gosu::ImageData> Gosu::Graphics::endRecording

(

)

Finishes building the macro and returns it as a drawable object.

Most usually, the return value is passed to Image::Image().
