colour.plotting.models Module¶

Colour Models Plotting¶

Defines the colour models plotting objects:

• colourspaces_CIE_1931_chromaticity_diagram_plot()
• single_transfer_function_plot()
• multi_transfer_function_plot()

colour.plotting.models.get_RGB_colourspace(colourspace)[source]¶

Returns the RGB colourspace with given name.

Parameters:	colourspace (unicode) – RGB Colourspace name.
Returns:	RGB Colourspace.
Return type:	RGB_Colourspace
Raises:	KeyError – If the given colourspace is not found in the factory colourspaces.

colour.plotting.models.colourspaces_CIE_1931_chromaticity_diagram_plot(colourspaces=None, cmfs='CIE 1931 2 Degree Standard Observer', **kwargs)[source]¶

Plots given colourspaces in CIE 1931 Chromaticity Diagram.

Parameters:	colourspaces (list, optional) – Colourspaces to plot. cmfs (unicode, optional) – Standard observer colour matching functions used for diagram bounds. **kwargs (**) – Keywords arguments.
Returns:	Definition success.
Return type:	bool

Examples

>>> csps = ['sRGB', 'ACES2065-1']
>>> colourspaces_CIE_1931_chromaticity_diagram_plot(csps)  
True

colour.plotting.models.single_transfer_function_plot(colourspace='sRGB', **kwargs)[source]¶

Plots given colourspace transfer function.

Parameters:	colourspace (unicode, optional) – RGB Colourspace transfer function to plot. **kwargs (**) – Keywords arguments.
Returns:	Definition success.
Return type:	bool

Examples

>>> single_transfer_function_plot()  
True

colour.plotting.models.multi_transfer_function_plot(colourspaces=None, inverse=False, **kwargs)[source]¶

Plots given colourspaces transfer functions.

Parameters:	colourspaces (list, optional) – Colourspaces transfer functions to plot. inverse (bool) – Plot inverse transfer functions. **kwargs (**) – Keywords arguments.
Returns:	Definition success.
Return type:	bool

Examples

>>> multi_transfer_function_plot(['sRGB', 'Rec. 709'])  
True
