Range

class supriya.tools.synthdeftools.Range(minimum=None, maximum=None)[source]

A range.

>>> synthdeftools.Range(-1., 1.)
Range(
    minimum=-1.0,
    maximum=1.0
    )
>>> synthdeftools.Range(minimum=0.)
Range(
    minimum=0.0,
    maximum=inf
    )
>>> synthdeftools.Range()
Range(
    minimum=-inf,
    maximum=inf
    )
>>> synthdeftools.Range((0.1, 0.9))
Range(
    minimum=0.1,
    maximum=0.9
    )
>>> synthdeftools.Range(synthdeftools.Range(-3, 3))
Range(
    minimum=-3.0,
    maximum=3.0
    )

Class & static methods

static Range.scale(value, input_range, output_range, exponent=1.0)[source]

Scales value from input_range to output_range.

Curve value exponentially by exponent.

>>> input_range = synthdeftools.Range(0., 10.)
>>> output_range = synthdeftools.Range(-2.5, 2.5)
>>> synthdeftools.Range.scale(0., input_range, output_range)
-2.5
>>> synthdeftools.Range.scale(5., input_range, output_range)
0.0
>>> synthdeftools.Range.scale(5., input_range, output_range, 2.)
-1.25
>>> synthdeftools.Range.scale(5., input_range, output_range, 0.5)
1.0355...

Returns float.

Special methods

(SupriyaObject).__eq__(expr)

Is true when ID of expr equals ID of Supriya object. Otherwise false.

Returns boolean.

(SupriyaObject).__format__(format_specification='')

Formats Supriya object.

Set format_specification to ‘’ or ‘storage’. Interprets ‘’ equal to ‘storage’.

Returns string.

(SupriyaObject).__hash__()

Hashes Supriya object.

Required to be explicitely re-defined on Python 3 if __eq__ changes.

Returns integer.

(SupriyaObject).__repr__()

Gets interpreter representation of Supriya object.

Returns string.
