Tonight I made a special effect using basic Microsoft GDI+. Here you would see the image and its code:
public static Bitmap IntelliPhoto4()
{
Bitmap IntelliPhoto = (Bitmap)Bitmap.FromFile(@"digital-photo3.bmp");
int height = IntelliPhoto.Height;
int width = IntelliPhoto.Width;
double dia = (int)Math.Sqrt(height * height + width * width);
for (int i = 0; i < height; i++)
{
for (int j = 0; j < width; j++)
{
Color pixColor = IntelliPhoto.GetPixel(j, i);
int sav = (pixColor.R + pixColor.G + pixColor.
/ 3 + 1;
int mav = (int)Math.Pow(pixColor.R * pixColor.G * pixColor.B, 0.333) + 1;
int g = (i * j) % 256;
int r = (i*(sav + mav) / 2) % 256;
int b = Math.Max(j*(r + g) / 2 % 256, 170);
// Step 1
if (g % 4 == 0)
IntelliPhoto.SetPixel(j, i, Color.FromArgb(r / 4, g / 4, b / 2));
else if (i * j % 10 == 0)
IntelliPhoto.SetPixel(j, i, Color.FromArgb(sav / 3, mav / 3, 255));
// Step 2
int trr = (int)Math.Sqrt(i * i + j * j);
int mod = (int)(255 - (255 * trr / dia));
pixColor = IntelliPhoto.GetPixel(j, i);
b = (int)Math.Min(pixColor.B + mod, 250);
g = (int)Math.Min(pixColor.G + mod, b * 0.95);
r = (int)Math.Min(pixColor.R + mod, r * 0.95);
IntelliPhoto.SetPixel(j, i, Color.FromArgb(r, g, b));
}
} // next i
return IntelliPhoto;
}
