Constructor & Destructor Documentation

render_target()

lxgui::gui::sfml::render_target::render_target	(	const vector2ui &	dimensions,
		material::filter	filt = material::filter::none
	)

Constructor.

Parameters

dimensions	The dimensions of the render_target
filt	The filtering to apply to the target texture when displayed

Member Function Documentation

begin()

void lxgui::gui::sfml::render_target::begin ( )

overridevirtual

Begins rendering on this target.

Implements lxgui::gui::render_target.

clear()

void lxgui::gui::sfml::render_target::clear ( const color &  c )

overridevirtual

Clears the content of this render_target.

Parameters

c	The color to use as background

Implements lxgui::gui::render_target.

end()

void lxgui::gui::sfml::render_target::end ( )

overridevirtual

Ends rendering on this target.

Implements lxgui::gui::render_target.

get_canvas_dimensions()

vector2ui lxgui::gui::sfml::render_target::get_canvas_dimensions ( ) const

overridevirtual

Returns this render target's canvas dimension.

Returns

This render target's canvas dimension

Note

This is the physical size of the render target. On some systems, abitrary dimensions are not supported: they can be promoted to the nearest power of two from for example.

Implements lxgui::gui::render_target.

get_material()

std::weak_ptr<sfml::material> lxgui::gui::sfml::render_target::get_material

(

)

Returns the associated texture for rendering.

Returns

The underlying pixel buffer, that you can use to render its content

get_rect()

bounds2f lxgui::gui::sfml::render_target::get_rect ( ) const

overridevirtual

Returns this render target's pixel rect.

Returns

This render target's pixel rect

Implements lxgui::gui::render_target.

get_render_texture()

sf::RenderTexture* lxgui::gui::sfml::render_target::get_render_texture

(

)

Returns the underlying SFML render texture object. return The underlying SFML render texture object.

save_to_file()

void lxgui::gui::sfml::render_target::save_to_file ( std::string  filename ) const

overridevirtual

Saves the content of this render target into a file.

Parameters

filename

The path of the file to save to

Note

The file format will be detected based on the extension. Not all renderer backends support all extensions.

Implements lxgui::gui::render_target.

set_dimensions()

bool lxgui::gui::sfml::render_target::set_dimensions ( const vector2ui &  dimensions )

overridevirtual

Sets this render target's dimensions.

Parameters

dimensions

The new dimensions (in pixels)

Returns

'true' if the function had to re-create a new render target

Implements lxgui::gui::render_target.
