Pixel Values [Resolved]

[chemicalNova]

Howdy all,

Ok, I might aswell try asking here. I've posted in the C/C++ forum because I don't believe many people come to this Assembly forum, but here goes.

I'm wanting to get the Red Green and Blue values of a pixel. I'm wanting something like these in Assembly (MASM, but any other is fine aswell).

//C++ Version
#define GetRValue(rgb)      ((BYTE)(rgb))
#define GetGValue(rgb)      ((BYTE)(((WORD)(rgb)) >> 8))
#define GetBValue(rgb)      ((BYTE)((rgb)>>16))

'VB Version
Function GetRedVal(val As Long) As Long
GetRedVal = val& Mod 256
End Function
 
Function GetGreenVal(val As Long) As Long
GetGreenVal = ((val And &HFF00) / 256&) Mod 256&
End Function
 
Function GetBlueVal(val As Long) As Long
GetBlueVal = (val And &HFF0000) / 65536
End Function

Any help is greatly appreciated.

Thanks in advance,

Phreak
