dgs.utils.image.compute_padding

dgs.utils.image.compute_padding(old_w: int, old_h: int, target_aspect: float) → list[int]

Given the width and height of an old and image, compute the size of a padding around the old image such that the aspect ratio matches a target.

Parameters:

• old_w – Width of the old image

• old_h – Height of the old image

• target_aspect – Aspect the new image should have (width / height).

Returns:

A list of integers as paddings for the left, top, right, and bottom side respectively.
