polymerist.graphics.imageutils

Tools for editing and manipulating images, and image colors, sizes, and representations

Functions

img_from_bytes(→ PIL.Image.Image)	Load an image from a bytestream
img_to_array(→ numpy.ndarray)	Convert an image to a numpy array
get_axis_bounds(→ tuple[tuple[int, int], tuple[int, int]])	Takes an image and returns a pair of tuples containing the min and max non-background
get_tight_bbox(→ tuple[int, Ellipsis])	Takes an image and returns a 4-tuple of the coordinates of the tight bounding box based on a choice of background color
crop_borders(→ PIL.Image.Image)	Takes an image and returns an image with all extraneous borders of a particular background color cropped off

Module Contents

polymerist.graphics.imageutils.img_from_bytes(img_bytes: bytearray) → PIL.Image.Image

Load an image from a bytestream

polymerist.graphics.imageutils.img_to_array(image: PIL.Image.Image, encoding: str = 'RGB') → numpy.ndarray

Convert an image to a numpy array

polymerist.graphics.imageutils.get_axis_bounds(image: PIL.Image.Image, bg_color: int | tuple[int]) → tuple[tuple[int, int], tuple[int, int]]

Takes an image and returns a pair of tuples containing the min and max non-background coordinates along the x- and y-axis (respectively) for some chosen background color

polymerist.graphics.imageutils.get_tight_bbox(image: PIL.Image.Image, bg_color: int | tuple[int]) → tuple[int, Ellipsis]

Takes an image and returns a 4-tuple of the coordinates of the tight bounding box based on a choice of background color

polymerist.graphics.imageutils.crop_borders(image: PIL.Image.Image, bg_color: int | tuple[int]) → PIL.Image.Image

Takes an image and returns an image with all extraneous borders of a particular background color cropped off
