|
|
|
new_region
|
new_region ( self, region )
Remembers new region but does not close existing model.
To display new region need to call show().
|
|
|
replace_components
|

|
|
|
same_region
|

|
|
|
save_orientation
|
save_orientation ( self )
|
|
|
set_parameters
|
set_parameters ( self, **kw )
Programatically set data region parameters. The following keyword
parameters are valid.
surface_levels
surface_colors (rgb or rgba values)
surface_brightness_factor
transparency_factor
solid_levels
solid_colors (rgb or rgba values)
transparency_depth
solid_brightness_factor
hidden
show_outline_box
use_colormap
If data set has more than one component than the component parameters
are specified as lists. The component parameters are the ones in the
first group above. For single component data a list is not used.
