RGB from COLORREF

Would you beleive it, 2 seconds after pressing post i got it.

			
col = GetPixel(dc2, c,r);   //col, row

unsigned long red = (col >> 0);
unsigned long green = (col >> 8);
unsigned long blue = col>>16;

You didnt search very har din MSDN! If you have searched for COLORREF in the index then used the color macro link at the bottom of that page you would''ve found:

GetBValue
GetRValue
GetGValue

Then again they do exactly what the code you have does anyway

Nah, he forgot to mask off the other parts:

col = GetPixel(dc2, c,r); //col, row

unsigned long red = ( (col >> 0) & 0xff );
unsigned long green = ( (col >> 8) & 0xff );
unsigned long blue = col>>16; // automaskoff

Thanks for those constructive responces.

I didn''t forget to mask, when i masked i only got dark shades of green.

Why unsigned longs, because the sample i ripped off, used them and why change what works.

The COLORREF had no getRValue... mentioned in the MSDN i have on CD, allthough i did find by typing getRValue...

Why am i doing this? I am doing a computer vision project that is going quite nicely, now that i can mess with RGB values from my webcam.
