Member Function Documentation

bool synfig::Target_Cairo_Tile::render ( ProgressCallback * cb = NULL )

virtual

Renders the canvas to the target.

Implements synfig::Target.

References _, synfig::ProgressCallback::amount_complete(), synfig::CAIRO, synfig::Canvas::create(), synfig::ProgressCallback::error(), synfig::optimize_layers(), and synfig::Context::set_render_method().

int Target_Cairo_Tile::next_tile	(	int &	x,
		int &	y
	)

virtual

Determines which tile needs to be rendered next.

Most cases will not have to redefine this function. The default should be adequate in nearly all situations.

Returns: The number of tiles left to go plus one. This means that whenever this function returns zero, there are no more tiles to render and that any value in x or y should be disregarded.

References synfig::Target::rend_desc().

int Target_Cairo_Tile::next_frame ( Time & time )

virtual

Returns the number of peniding frames to render. If it is zero it stops rendering frames.

Reimplemented from synfig::Target.

virtual bool synfig::Target_Cairo_Tile::add_tile	(	cairo_surface_t *	surface,
		int	x,
		int	y
	)

pure virtual

Adds the tile at x , y contained in surface.

virtual int synfig::Target_Cairo_Tile::total_tiles ( ) const

inlinevirtual

Returns the total tiles of the imaged rounded to integer number of tiles.

References synfig::Target::rend_desc().

void synfig::Target_Cairo_Tile::set_threads ( int x )

inline

Sets the number of threads.

int synfig::Target_Cairo_Tile::get_threads ( ) const

inline

Gets the number of threads.

void synfig::Target_Cairo_Tile::set_tile_w ( int w )

inline

Sets the tile widht.

int synfig::Target_Cairo_Tile::get_tile_w ( ) const

inline

Gets the tile widht.

void synfig::Target_Cairo_Tile::set_tile_h ( int h )

inline

Sets the tile height.

int synfig::Target_Cairo_Tile::get_tile_h ( ) const

inline

Gets the tile height.

bool synfig::Target_Cairo_Tile::get_clipping ( ) const

inline

Gets clipping.

void synfig::Target_Cairo_Tile::set_clipping ( bool x )

inline

Sets clipping.

virtual bool synfig::Target_Cairo_Tile::start_frame ( ProgressCallback * cb = NULL )

pure virtual

Marks the start of a frame.

Returns: true on success, false upon an error.

See Also: end_frame()

virtual void synfig::Target_Cairo_Tile::end_frame ( )

pure virtual

Marks the end of a frame.

See Also: start_frame()

void Target_Cairo_Tile::gamma_filter	(	cairo_surface_t *	surface,
		const synfig::Gamma	gamma
	)

static

Filters the cairo surface based on gamma (hardcored for the moment to 2.2)
