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.
