Detailed Description

An OrthoCPUProducer whose tiles can be edited at runtime.

Intended to be used with an EditOrthoProducer.

proland::EditOrthoCPUProducer::EditOrthoCPUProducer	(	ptr< TileCache >	cache,
		const char *	name
	)

See OrthoCPUProducer.

virtual proland::EditOrthoCPUProducer::~EditOrthoCPUProducer ( ) [virtual]

proland::EditOrthoCPUProducer::EditOrthoCPUProducer ( ) [protected]

Creates an uninitialized EditOrthoCPUProducer.

void proland::EditOrthoCPUProducer::editedTile	(	int	level,
		int	tx,
		int	ty,
		int *	deltaColor
	)

Notifies this producer that a tile has been edited.

Parameters:

	level	the level of the edited tile.
	tx	the logical x coordinate of the edited tile.
	ty	the logical y coordinate of the edited tile.
	deltaColor	the difference between the new and the previous color values of the edited tile. Does not include borders.

int* proland::EditOrthoCPUProducer::getDeltaColor	(	int	level,
		int	n,
		int	tx,
		int	ty,
		int	x,
		int	y
	)			`[private]`

Returns the color delta at the given location.

Parameters:

	level	a quadtree level.
	n	the numbers of tiles per row or column in the quadtree at this level (1 << level).
	tx	a logical tile x coordinate.
	ty	a logical tile y coordinate.
	x	a pixel coordinate relatively to the lower left corner of the (level,tx,ty) tile (without borders). Can be outside the tile itself (then the value will be looked up in an adjacent tile).
	y	a pixel coordinate relatively to the lower left corner of the (level,tx,ty) tile (without borders). Can be outside the tile itself (then the value will be looked up in an adjacent tile).
