Folks,

I have a raw pixel data array that is 16bppGrayScale. The data is in a 1-d byte array, 2 bytes per pixel, padded to end

a row on a 4 byte bounday (held in image.Data below)

Here is my code that doesn't draw? What is wrong? ?????

same code works if I read the bmp in from disk and instead of assigning dataArray = image.Data, do byte[] dataArray = new byte[height*width*3];

Bitmap bmp = new Bitmap(image.ImageWidth, image.ImageLength, PixelFormat.Format16bppGrayScale);

Rectangle rect = new Rectangle(0, 0, bmp.Width, bmp.Height);

BitmapData bmpData = bmp.LockBits(rect, ImageLockMode.ReadWrite, PixelFormat.Format16bppGrayScale);

IntPtr ptr = bmpData.Scan0;

int limit = image.Data.Length;

byte[] dataArray = image.Data;

Marshal.Copy(ptr, dataArray, 0, dataArray.Length);

bmp.UnlockBits(bmpData);

e.Graphics.DrawImage(bmp, 0, 0);

It is doubtful that you have a 16 bit graphics card, so convert the data to 8 bits before creating the bitmap.
