class SpatialImage(image, dtype=<class 'numpy.float32'>)[source]#

Bases: object

Object encapsulating a spatial volume image instance of Image.

Channel is not supported in this version.

Creates an instance.

Parameters:

  • image (Image) – An instance of Image.

  • dtype (Numpy type, optional) – Defaults to np.float32.

__init__(image, dtype=<class 'numpy.float32'>)[source]#

Creates an instance.

Parameters:

  • image (Image) – An instance of Image.

  • dtype (Numpy type, optional) – Defaults to np.float32.

property affine#

Affine of the re-oriented image data, or None

get_data()[source]#

Returns the image array in ndarray

get_property(key, default=None)[source]#

Gets value of the specified property

Parameters:

  • key (str) – key of the property

  • default – default value if the property does not exist.

Returns:

the value of the property, or the default value if property does not exist.

property image_array#

Image data in Numpy array, or None

property itk_image#

ITK image object created from the encapsulated image object, or None

property original_affine#

Original affine of the image, or None

set_property(key, value)[source]#

Sets an image property

Parameters:

  • key (str) – key of the property

  • value – value of the property

property shape#

Shape of image array, or None

property spacing#

Pixel spacing of original image, aka resolution, or None

__init__(*args, **kwargs)[source]#

Creates an instance to generate a surface mesh in STL with an Image object.

convert(image, output_file=None, class_ids=None, is_smooth=True, keep_largest_connected_component=True)[source]#
Parameters:

  • image (Image) – object with the image (ndarray of DHW index order) and its metadata dictionary.

  • output_file (str) – output STL file path. Default to None for not saving output file.

  • class_id (array, optional) – Class label id. Defaults to None.

  • is_smooth (bool, optional) – smoothing or not. Defaults to True.

  • keep_largest_connected_component (bool, optional) – Defaults to True.

Returns:

Bytes of the binary STL file.
