Image.Squares

classmethod Image.Squares(number: int, *, size: int | Sequence[int] | None = None, fg: Any = 1, bg: Any = 0, dtype: Dtype | None = None, colororder: str | None = None, like=None) → Self

Create image containing grid of squares

Parameters:

• number (int) – number of squares horizontally and vertically

• size (int or 2-tuple, optional) – image size; scalar gives a square image, defaults to 256

• fg (int, float, optional) – pixel value of the squares, defaults to 1

• bg (int, optional) – pixel value of the background, defaults to 0

• dtype (str or NumPy dtype, optional) – NumPy datatype, defaults to ‘uint8’

• colororder (str or None, optional) – color plane names for the output image, defaults to None

• like (Image or None, optional) – template image supplying default size, dtype and colororder when those are not given explicitly

Returns:

grid of squares

Return type:

Image

The image background is set to bg and the circles are filled with fg.

Example:

>>> from machinevisiontoolbox import Image
>>> img = Image.Squares(2, size=14, bg=1, fg=9)
>>> img.print()
