lets_plot.bistro.im.image_matrix

lets_plot.bistro.im.image_matrix(image_data_array, *, norm: Optional[bool] = None, scale=1) → lets_plot.plot.plot.GGBunch

Display images in a grid. The grid dimensions are determined by shape of the input 2D ndarray.

Elements of the input 2D array are images specified by ndarrays with shape (n, m) or (n, m, 3) or (n, m, 4).

Parameters

image_data_arrayndarray

2D numpy.ndarray containing images. Specifies dimensions of output grid.

normbool, default=True

False value disables default scaling of a luminance (grayscale) images to the (0, 255) range.

scalefloat, default=1.0

Specifies magnification factor.

Returns

GGBunch

Plot bunch object.
