Hi,
Buffer.BlockCopy() and Array.Copy() seem do be fine for Arrays, but what to
do about copying memory in unsafe code?
The goal is simple, I just want to scroll the content of an Image vertically
for some lines.. (using the CompactFramework, but seems to be of general
interrest). So I moved byte-per-byte which is awfully slow :(

Code:
System.Drawing.Imaging.BitmapData bd = buffer.LockBits(all,
System.Drawing.Imaging.ImageLockMode.ReadWrite,
System.Drawing.Imaging.PixelFormat.Format16bppRgb555);
int cnt = ((buffer.Height - Math.Abs(lines)) * bd.Stride);
byte* src = (byte*)bd.Scan0.ToInt32() + lines * bd.Stride;
byte* dst = (byte*)bd.Scan0.ToInt32();

for (int i = 0; i < cnt; i++)
{
   *dst = *src;
   dst++;
   src++;
}

I really would like to see this for-loop removed by some "native" code...
any suggestions?!

Thanks,
 Johannes
