Public Member Functions
	MinimalBinding (Framebuffer &fbo)
	Binds fbo as the current framebuffer.
virtual	~MinimalBinding ()
	Retracts this binding and restores the previous one.
void	setColorComponent (Texture< 2 > &renderTexture, unsigned int location=0)
	Attaches renderTexture as the color component at location of the bound framebuffer object.
void	removeColorComponent (unsigned int location)
	Removes color component at location from bound framebuffer object.
Color	readPixel (unsigned int x, unsigned int y, unsigned int location=0) const
	Reads the color of the pixel located at x and y within the color attachment at location.
const Framebuffer &	framebuffer () const
	References the bound framebuffer.
virtual void	refresh () const
	Re-performs this binding. This is useful if the currently bound framebuffer has been changed through a different mechanism, e.g. using OpenGL calls directly or by another API.

Protected Attributes
Framebuffer &	fbo
	References the bound framebuffer.

Detailed Description

Maintains the binding of a Framebuffer in a RAII-manner.

Bound framebuffers are not checked for validity. Allows manipulation of the bound framebuffer, but not rendering. Use a full Binding if you want to render to the framebuffer.

readPixel()

Color LibCarna::base::Framebuffer::MinimalBinding::readPixel	(	unsigned int	x,
		unsigned int	y,
		unsigned int	location = 0
	)		const

Reads the color of the pixel located at x and y within the color attachment at location.

Precondition

This is the latest framebuffer binding.

refresh()

virtual void LibCarna::base::Framebuffer::MinimalBinding::refresh ( ) const

virtual

Re-performs this binding. This is useful if the currently bound framebuffer has been changed through a different mechanism, e.g. using OpenGL calls directly or by another API.

Precondition

This is the latest framebuffer binding.

removeColorComponent()

void LibCarna::base::Framebuffer::MinimalBinding::removeColorComponent

(

unsigned int

location

)

Removes color component at location from bound framebuffer object.

Precondition

This is the latest framebuffer binding.

setColorComponent()

void LibCarna::base::Framebuffer::MinimalBinding::setColorComponent	(	Texture< 2 > &	renderTexture,
		unsigned int	location = 0
	)

Attaches renderTexture as the color component at location of the bound framebuffer object.

Precondition

This is the latest framebuffer binding.

If there was another color component bound to location previously, it is replaced.
