from_range_degrees
(a, scale_factor=360)[source]¶ Scales given array \(a\) from degrees range. The behaviour is as follows:
If Colour domain-range scale is ‘Reference’, the definition is entirely by-passed.
If Colour domain-range scale is ‘1’, array \(a\) is divided by
scale_factor
, typically 360.If Colour domain-range scale is ‘100’ (currently unsupported private value only used for unit tests), array \(a\) is divided by
scale_factor
/ 100, typically 360 / 100.
- Parameters
a (array_like) – \(a\) to scale from degrees range.
scale_factor (numeric or array_like, optional) – Scale factor, usually numeric but can be an array_like if some axis need different scaling to be brought from degrees range.
- Returns
\(a\) scaled from degrees range.
- Return type
ndarray
Examples
With Colour domain-range scale set to ‘Reference’:
>>> with domain_range_scale('Reference'): ... from_range_degrees(1) 1
With Colour domain-range scale set to ‘1’:
>>> with domain_range_scale('1'): ... from_range_degrees(1) 0.0027777...
With Colour domain-range scale set to ‘100’ (unsupported):
>>> with domain_range_scale('100'): ... from_range_degrees(1) 0.2777777...
