Displaying 16 bit raw images

Recommended Posts

If I have an array of data (16 bit values) that represent pixel intensity (in other words a grayscale image), can anyone tell me how to display this data in a picture box in an MFC application? If the code is long or complicated I guess don't worry about it, but it seems like a simple thing that I've just spent way too much time digging around trying to solve. Thanks, Andrew

I'm not much in the MFC, but AFAIK you have a Paint event for the picture box.
In it, you can do a blit to the HWND with the data, but I guess you'll need some data transforming before.

I would create a bitmap in memory. I'm not sure if there's an standard 16 bits greyscale bmp, but you can always do:


unsigned char R,G,B;
for (i = 0; i < ArraySize; i++)
{
int Luminance = Array[i] * 256 / 65535;
R = G = B = Luminance;
...
}


And fill up a BitmapInfo structure with these values.
