Envelope.fromXY constructor

Envelope.fromXY({
  1. required double xMin,
  2. required double yMin,
  3. required double xMax,
  4. required double yMax,
  5. SpatialReference? spatialReference,
})

Creates an envelope based on the x,y coordinates with a spatial reference.

If the values for min parameters are bigger than max parameters then they are re-ordered. The resulting envelope always has min less than or equal to max.

Parameters:

  • xMin — The minimal x-value.
  • yMin — The minimal y-value.
  • xMax — The maximum x-value.
  • yMax — The maximum y-value.
  • spatialReference — The spatial reference for the envelope.

Implementation

factory Envelope.fromXY({
  required double xMin,
  required double yMin,
  required double xMax,
  required double yMax,
  SpatialReference? spatialReference,
}) {
  _initializeArcGISEnvironmentIfNeeded();
  final handle = _withThrowingErrorHandler((errorHandler) {
    return runtimecore.RT_Envelope_createWithXYSpatialReference(
      xMin,
      yMin,
      xMax,
      yMax,
      spatialReference?._handle ?? ffi.nullptr,
      errorHandler,
    );
  });
  final Envelope object = Envelope._withHandle(handle);
  object._spatialReference.cache(spatialReference);
  return object;
}
