# HGE Hardware color format Several HGE functions use color as a parameter or return value. It is just a DWORD, containing four 8-bit values for Red, Green, Blue and Alpha color components in the following way: 0xAARRGGBB. I.e. the highest BYTE of DWORD contains the Alpha value. The next BYTE contains the Red value. Then goes Green value. And the lowest BYTE contains Blue value. ## Macros You could use these macros to manipulate DWORD color values:
    ARGB(a,r,g,b)
      ((DWORD(a)<<24) + (DWORD(r)<<16) + (DWORD(g)<<8) + DWORD(b))
ARGB macro builds a DWORD color value from it's components.
    GETA(col)      ((col)>>24)
    GETR(col)      (((col)>>16) & 0xFF)
    GETG(col)      (((col)>>8) & 0xFF)
    GETB(col)      ((col) & 0xFF)
GETA, GETR, GETG and GETB macros return the specified component of the composite DWORD.
    SETA(col,a)    (((col) & 0x00FFFFFF) + (DWORD(a)<<24))
    SETR(col,r)    (((col) & 0xFF00FFFF) + (DWORD(r)<<16))
    SETG(col,g)    (((col) & 0xFFFF00FF) + (DWORD(g)<<8))
    SETB(col,b)    (((col) & 0xFFFFFF00) + DWORD(b))
SETA, SETR, SETG and SETB macros change the specified component of the composite DWORD. ## Requirements Header: hge.h ## See also hgeColor helper class
