Public Sub TransformPoints (destSpace As CoordinateSpace, srcSpace As CoordinateSpace, pts As Point())
Public Sub TransformPoints (destSpace As CoordinateSpace, srcSpace As CoordinateSpace, ParamArray pts As Point())

Parameter

destSpace
CoordinateSpace

Anggota enumerasi CoordinateSpace yang menentukan ruang koordinat tujuan.

srcSpace
CoordinateSpace

Anggota enumerasi CoordinateSpace yang menentukan ruang koordinat sumber.

pts
Point[]

Array struktur Point yang mewakili titik transformasi.

Contoh

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

  • Membuat dua poin dan menggambar garis biru di antaranya.

  • Mengatur transformasi dunia untuk diterjemahkan dengan jumlah 40 ke arah x dan 30 ke arah y.

  • Mengubah titik dari koordinat dunia (World) menjadi koordinat halaman (Page).

  • Mengatur ulang transformasi dunia ke identitas.

  • Menggambar garis merah di antara titik yang diubah.

Hasilnya adalah garis biru dan garis merah yang diterjemahkan di bawahnya.
