How to convert Bitmap to byte[,,] faster?
- by Miko Kronn
I wrote function:
public static byte[, ,] Bitmap2Byte(Bitmap image)
{
int h = image.Height;
int w = image.Width;
byte[, ,] result= new byte[w, h, 3];
for (int i = 0; i < w; i++)
{
for (int j = 0; j < h; j++)
{
Color c= image.GetPixel(i, j);
result[i, j, 0] = c.R;
result[i, j, 1] = c.G;
result[i, j, 2] = c.B;
}
}
return result;
}
But it takes almost 6 seconds to convert 1800x1800 image. Can I do this faster?
