Function Documentation

Eina_Iterator* eina_tile_grid_slicer_iterator_new	(	int	x,
		int	y,
		int	w,
		int	h,
		int	tile_w,
		int	tile_h
	)

Creates a new Eina_Iterator that slices over a list of tiles.

Parameters:

x	X axis coordinate.
y	Y axis coordinate.
w	width.
h	height.
tile_w	tile width.
tile_h	tile height.

Returns:

A pointer to the Eina_Iterator. NULL on failure.

The tile grid is defined by tile_w and tile_h while the region is defined by x, y, w, h. The output is given as Eina_Tile_Grid_Info where tile index is given in col col and row row with tile-relative coordinates in x, y, w, h. If tile was fully filled by region, then full flag is set.
