void stg_rotrects_normalize	(	stg_rotrect_t *	rects,
		int	num
	)

normalizes the set [rects] of [num] rectangles, so that they fit exactly in a unit square.

int stg_rotrects_from_image_file	(	const char *	filename,
		stg_rotrect_t **	rects,
		int *	rect_count,
		int *	widthp,
		int *	heightp
	)

load the image file [filename] and convert it to an array of rectangles, filling in the number of rects, width and height. Memory is allocated for the rectangle array [rects], so the caller must free [rects].

stg_polygon_t* stg_polygons_from_rotrects	(	stg_rotrect_t *	rects,
		size_t	count
	)

converts an array of rectangles into an array of polygons

load [filename], an image format understood by gdk-pixbuf, and return a set of rectangles that approximate the image. Caller must free the array of rectangles. If width and height are non-null, they are filled in with the size of the image in pixels
