rasterContrast property

NSExpression get rasterContrast

Increase or reduce the contrast of the image.

The default value of this property is an expression that evaluates to the float 0. Set this property to nil to reset it to the default value.

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

Constant numeric values between −1 and 1 inclusive Predefined functions, including mathematical and string operators Conditional expressions Variable assignments and references to assigned variables Interpolation and step functions applied to the $zoomLevel variable

This property does not support applying interpolation or step functions to feature attributes.

Implementation

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