points
PointF[]

Array struktur PointF yang menentukan spline.

tension

Contoh

Contoh kode berikut dirancang untuk digunakan dengan Windows Forms, dan memerlukan PaintEventArgse, yang merupakan parameter penanganan aktivitas Paint. Kode melakukan tindakan berikut:

  • Membuat pena merah dan hijau.

  • Membuat tujuh poin untuk menentukan kurva.

  • Menggambar tujuh garis lurus merah di antara tujuh poin untuk membentuk poligon.

  • Membuat pengaturan mode ketegangan dan pengisian.

  • Menarik kurva tertutup hijau melalui tujuh poin.

Metode ini menggunakan ketegangan 1.0 dan mengatur mode isi ke FillMode.Alternate.

Keterangan

Metode ini menarik spline kardinal tertutup yang melewati setiap titik dalam array. Jika poin terakhir tidak cocok dengan poin pertama, segmen kurva tambahan ditambahkan dari titik terakhir ke titik pertama untuk menutupnya.

Array titik harus berisi setidaknya empat struktur PointF.

Parameter tension menentukan bentuk spline. Jika nilai parameter tension adalah 0,0F, metode ini menarik segmen garis lurus untuk menghubungkan titik. Biasanya, parameter tension kurang dari atau sama dengan 1,0F. Nilai di atas 1,0F menghasilkan hasil yang tidak biasa.
