Out put :

Dari program di atas kita menampilkan Layer Red, Green dan Blue, selain itu kita juga menampilkan Grayscale Red, Green, Blue.

pada setiap layer kita hanya menampilkan sisi warna tipe layer pada setiap pixelnya, sehingga hasil nya seperti di atas. seperti ini “Color new_w = Color.FromArgb(wb, wb, wb)”

pada gray scale kita hanya merubah bagian RGB tertentu menjadi warna RGB tipe gray scale dan yang lain nya menjadi 0. seperti ini “Color new_w = Color.FromArgb(0, 0, wb)”

jadi dari program dan output di atas, kita melakukan flip Horizontal, Vertical, Rotate 90 dan Rotate 180. kita melakukan program tersebut memindahkan setiap pixel RGB nya. ehehehhe 🙂
