expandBy method
- double factor,
- {ArcGISPoint? anchor}
Expands the envelope at the anchor point by the given factor.
A factor of less than 1.0 shrinks the envelope and greater than 1.0 expands it.
Parameters:
factor
— The factor to scale the envelope by.anchor
— The point at which to anchor the expansion. If null, EnvelopeBuilder.center is used as the anchor point.
Implementation
void expandBy(double factor, {ArcGISPoint? anchor}) {
_withThrowingErrorHandler((errorHandler) {
runtimecore.RT_EnvelopeBuilder_expandCombined(
_handle, factor, anchor?._handle ?? ffi.nullptr, errorHandler);
});
}
