make_bounds_size_positive(bounds)[source]¶

Make bounds have positive size and get horizontal/vertical flip flags.

Bounds with a negative size in either direction with have the coordinates swapped (e.g. left and right or top and bottom swapped) and a respective horizontal or vertical flip flag set in the output to reflect the swaps which occurred.

Parameters:: bounds (IntBounds) – Length 4 array of bounds.
Returns:: Three tuple containing positive bounds and flips: - numpy.ndarray - Positive bounds - bool - Horizontal flip - bool - Vertical flip
Return type:: tuple

Examples

>>> from tiatoolbox.utils.image import make_bounds_size_positive
>>> bounds = (10, 10, 0, 0)
>>> positive_bounds, flipud, fliplr = make_bounds_size_positive(bounds)
