This might help.

public uint[] ConvertGray16ToRGB(ushort[] grayPixels, int bitsUsed) {
int pixelCount = grayPixels.Length;
uint[] rgbPixels = new uint[pixelCount];
int shift = bitsUsed - 8;
for (int i = 0; i < pixelCount; i++) {
uint gray = (uint)grayPixels[i] >> shift;
rgbPixels[i] = 0xff000000U | gray | (gray << 8) | (gray <<
16);
}
return(rgbPixels);
}
Success,

I am also trying to display 16bpp grayscale images. What is the right
way to convert them into RGB format? I devided each pixel value by 3
and assign the result to R/G/B. But the resultant images have lost
contrast almost completely. Any pointers are appreciated!

However you may be interested in the FreeImage library on SourceForge which
has a C# wrapper and supports lots of image formats.

news:D7**********************************@microsof t.com... After searching newsgroups and discussions, i came to the following
conclusion.
Even though PixelFormat.Format16bppGrayScale is defined, it's NOT and will
NEVER
be supported by the .NET framework.
For our business (medical imaging), this is very disappointing.
16 bit gray is most common imageformat used for medical imaging.
Scaling back to 8 bit is not an option. We really need 16 bit accuracy
in our processing operations.
Does this mean that .NET is not meant for professional imaging?
Please reconsider support for 16 bit gray.
Thanks,
