keepsTextUpright property

NSExpression get keepsTextUpright

If true, the text may be flipped vertically to prevent it from being rendered upside-down.

The default value of this property is an expression that evaluates to YES. Set this property to nil to reset it to the default value.

This property is only applied to the style if text is non-nil, and textRotationAlignment is set to an expression that evaluates to map, and symbolPlacement is set to an expression that evaluates to either MLNSymbolPlacementLine or MLNSymbolPlacementLineCenter. Otherwise, it is ignored.

This attribute corresponds to the text-keep-upright layout property in the MapLibre Style Spec.

You can set this property to an expression containing any of the following:

Constant Boolean values Predefined functions, including mathematical and string operators Conditional expressions Variable assignments and references to assigned variables Step functions applied to the $zoomLevel variable

This property does not support applying interpolation functions to the $zoomLevel variable or applying interpolation or step functions to feature attributes.

Implementation

NSExpression get keepsTextUpright {
  final _ret = _objc_msgSend_151sglz(this.ref.pointer, _sel_keepsTextUpright);
  return NSExpression.castFromPointer(_ret, retain: true, release: true);
}
set keepsTextUpright (NSExpression value)
