İki geometri arasındaki simetrik farkı döndürür.
Kullanım | İadeler |
---|
MultiPoint.symmetricDifference(right, maxError, proj) | Geometri |
Bağımsız Değişken | Tür | Ayrıntılar |
---|
bu: left | Geometri | İşlemin sol işleneni olarak kullanılan geometri. |
right | Geometri | İşlemin sağ işleni olarak kullanılan geometri. |
maxError | ErrorMargin, varsayılan: null | Gerekli yeniden projeksiyon işlemleri gerçekleştirilirken tolere edilen maksimum hata miktarı. |
proj | Projeksiyon, varsayılan: null | İşlemin gerçekleştirileceği projeksiyon. Belirtilmemişse işlem küresel bir koordinat sisteminde gerçekleştirilir ve doğrusal mesafeler kürede metre cinsinden olur. |
