        self,
        use_step=True,
        use_subregion=True,

        )

Return the origin and size of the subsampled submatrix to be read. Also return the subsampling factor and additional step (ie stride) that must be used to get the displayed data.

copy ( self )

remove_volume_change_callback ( self,  cb )

data_changed_cb ( self,  type )

Either the data values or coordinates have changed. Surface / solid rendering is not automatically redrawn when data values change.

        self,
        source_to_world_xform,
        use_subregion,
        use_step,
        )

Returns 3-d numeric array and transformation from a given "source" coordinate system to array indices. The source_to_world_xform transforms from the source coordinate system to Chimera world coordinates. If the transform is None it means the source coordinates are the same as the volume local coordinates.

        rendering_options,

transfer_function ( self )

Without brightness and transparency adjustment.
