Extracting the A,R,G and B from a D3DCOLOR
Author
Given a D3DCOLOR, how would I go about extracting the Alpha, Red, Green and Blue components into seperate ints?
Well, looking at MSDN, it says that D3DCOLOR is defined as:
So, you should be able to extract the info as this:
... or the other way around (change the order of a r g b.. dunno about it)

typedef DWORD D3DCOLOR So, you should be able to extract the info as this:
a = (myColor >> 24) & 0xFF;r = (myColor >> 16) & 0xFF;g = (myColor >> 8) & 0xFF;b = myColor & 0xFF; ... or the other way around (change the order of a r g b.. dunno about it)

Yep, your right, the order is 0xAARRGGBB, so use a bitwise AND '&&'. EDIT: I mean '&'... woops...

He did use a bitwise and. You''re using a logical and, and calling it bitwise. Please drink more coffee.
You could also use the GetRValue(), GetBValue(), and GetGValue() win32 functions. Check it out in msdn.
Yeah, but they doesn''t seem to have an GetAValue() :/
You would think that they would write those kind of functions down in the D3DCOLOR-document.
