ColorBlend()

Sumber:

ColorBlend.cs

Menginisialisasi instans baru kelas ColorBlend.

public:
 ColorBlend();

public ColorBlend ();

Public Sub New ()

Contoh

Contoh berikut dimaksudkan untuk digunakan di lingkungan Formulir Windows. Ini menunjukkan cara menggunakan ColorBlend kelas bersama dengan LinearGradientBrush kelas untuk menggambar elips ke layar yang memiliki warna yang dipadukan. Elips berwarna hijau di sebelah kiri, memadukan ke kuning, kemudian menjadi biru, dan akhirnya berwarna merah di sebelah kanan. Ini dicapai melalui pengaturan dalam myColors array dan myPositions yang digunakan dalam Colors properti dan Positions . Perhatikan bahwa InterpolationColors properti objek LinearGradientBrush bernama lgBrush2 harus dibuat sama dengan ColorBlend objek myBlend.
