Function Documentation

static int find_image_range	(	int *	pfirst_index,
		int *	plast_index,
		const char *	path,
		int	start_index,
		int	start_index_range
	)			[static]

Get index range of image files matched by path.

Parameters:

	pfirst_index	pointer to index updated with the first number in the range
	plast_index	pointer to index updated with the last number in the range
	path	path which has to be matched by the image files in the range
	start_index	minimum accepted value for the first index in the range

Returns:

-1 if no image file could be found
