canvas (QgsMapCanvas) –
- setMaximumScale(self, scale: float)¶
Set the maximum

Warning
Calling
setMinimumScale()
places a restriction on the acceptable maximum scale for the widget, and will alter any previously set maximum scale to pass this constraint. Always callsetMinimumScale()
beforesetMaximumScale()
when restoring a scale range in the widget, or use the convenience methodsetScaleRange()
instead.- Parameters
scale (float) –
- setMinimumScale(self, scale: float)¶
Set the minimum
scale
(i.e. most “zoomed out” scale), or 0 to indicate the minimum is not set. The scale value indicates the scale denominator, e.g. 1000.0 for a 1:1000 map.See also
