Byte Array to Bitmap using Unsafe in c#

Asked by Ameerh24 in C# Programming Language, .NET Framework 2.x, Microsoft Visual C#.Net

Tags: Dot Net 2005, c#

Hi All,
I am pretty new to bitmap manipulations. I have a byte array and i need a bitmap out of that. I am using the below code to get the bitmap.

if (imgByte != null)
            {
                BitmapData bmpData = bmp.LockBits(new Rectangle(0, 0, bmp.Width, bmp.Height), ImageLockMode.WriteOnly, bmp.PixelFormat);
                Marshal.Copy(imgByte, 0, bmpData.Scan0, ImageHeight * (int)lngPitch);

                bmp.UnlockBits(bmpData);
            }

But it is taking too much CPU usage. I know the performance can be enhanced by using the unsafe code. Can anyone please help me or give me the code to enhance the byte array manipulation to construct a bitmap.

Any help is highly appreciated.

Thanks
