This module contains utility classes and functions for internal use only.

Validate that all color values in the image are integers and within the correct range (0 to 255). If the image contains any float values or out-of-range values, it will raise a ValueError.

Parameters:

image (numpy.ndarray) – The image array to validate (can be RGB or Grayscale).

Raises:

ValueError – If any value in the image is invalid (float or out-of-range).

static _input_checker(img_array)

Validate the input image array for proper format, shape, and value range.

This function checks if the input image array meets the following conditions: - It is a NumPy array. - It is either a 2D array (grayscale) or a 3D array with three channels (RGB). - It is non-empty and has no zero-sized dimensions. - It has an integer data type. - All values in the array are within the range [0, 255].

Parameters:

img_array (numpy.ndarray) – The image array to validate.

Returns:

Returns True if all validation checks pass.

Return type:

bool

Raises:

• TypeError – If the input is not a NumPy array or does not have an integer data type.

• ValueError – If the input array is not 2D or 3D with three channels, is empty, has zero-sized dimensions, or contains values outside the range [0, 255].
