cigvis.sliceviewer.nodes module

Internal node types for sliceviewer.

class cigvis.sliceviewer.nodes.MaskSpec(volume: ndarray, cmap: object, clim: Tuple[float, float])

Bases: object

An overlay volume attached to a SliceNode.

clim: Tuple[float, float]

cmap: object

volume: ndarray

class cigvis.sliceviewer.nodes.SliceNode(volume: ~numpy.ndarray, display_axes: ~typing.Tuple[int, int], indices: ~typing.Dict[int, int], cmap: object, clim: ~typing.Tuple[float, float], aspect: str | float = 1.0, interpolation: str | bool | None = 'nearest', render_mode: str = 'rgba', axis_labels: ~typing.Tuple[str, ...] = <factory>, masks: ~typing.List[~cigvis.sliceviewer.nodes.MaskSpec] = <factory>, _linked: ~cigvis.sliceviewer.nodes.SliceNode | None = None)

Bases: object

Render a 2D frame from a 2D/3D/4D array.

aspect: str | float = 1.0

axis_name(axis: int) → str

axis_short_name(axis: int) → str

clamp_axis_index(axis: int, idx: int) → int

clim: Tuple[float, float]

cmap: object

display_axes: Tuple[int, int]

property ndim: int

render() → ndarray

Blend base slice + all masks into an RGBA uint8 (h, w, 4) array. Uses cigvis.colormap.arrs_to_image, same as the 3D viewers.
