minScale
(self) → float¶ Returns the minimum scale, or 0 if no minimum scale set. The
scale
value indicates the scale denominator, e.g. 1000.0 for a 1:1000 map. Any scale lower than the minimum scale will automatically be converted to the minimum scale. Except for 0 which is always allowed.- Return type
float

toDouble
(string: str) → Tuple[float, bool]¶ Helper function to convert a scale
string
to double. The returned value indicates the scale denominator, e.g. 1000.0 for a 1:1000 map. If specified,ok
will be set to true if the string was successfully interpreted as a scale.See also
- Parameters
string (str) –
- Return type
Tuple[float, bool]

toString
(scale: float) → str¶ Helper function to convert a
scale
double to scale string. Thescale
value indicates the scale denominator, e.g. 1000.0 for a 1:1000 map.The returned string will be rounded (e.g. 1:1000, not 1:1000.345).
