classmethod Image.Zeros(w, h=None, colororder=None, dtype='uint8')

Create image with zero value pixels

Parameters:

  • w (int, (int, int)) – width, or (width, height)

  • h (int, optional) – height, defaults to None

  • colororder (str) – color plane names, defaults to None

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

Returns:

image of zero values

Return type:

Image

Create a greyscale image of zero-valued pixels. If only one dimension is given the image is square.

Example:

>>> from machinevisiontoolbox import Image
>>> Image.Zeros(20)
Image: 20 x 20 (uint8)
>>> Image.Zeros(10,20)
Image: 10 x 20 (uint8)
>>> Image.Zeros(20, dtype='float', colororder="RGB") # create color image, all black
Image: 20 x 20 (float64), R:G:B
