Define Documentation

#define GetBValue (  rgb   )     ((BYTE)((rgb) >> 16))

Gets the blue component from a RGB triple value rgb. You can make a RGB triple by using MakeRGB. See also: MakeRGB Definition at line 507 of file common.h.

#define GetGValue (  rgb   )     ((BYTE)(((WORD)(rgb)) >> 8))

Gets the green component from a RGB triple value rgb. You can make a RGB triple by using MakeRGB. See also: MakeRGB Definition at line 498 of file common.h.

#define GetRValue (  rgb   )     ((BYTE)(rgb))

Gets the red component from a RGB triple value rgb. You can make a RGB triple by using MakeRGB. See also: MakeRGB Definition at line 489 of file common.h.

#define HIBYTE (  w   )     ((BYTE)(((WORD)(w) >> 8) & 0xFF))

Returns the high byte of the word w. See also: MAKEWORD Definition at line 437 of file common.h.

#define HISWORD (  l   )     ((SWORD)((((DWORD)(l)) >> 16) & 0xFFFF))

Returns the high signed word of the double word l. See also: MAKELONG Definition at line 473 of file common.h.

#define HIWORD (  l   )     ((WORD)((((DWORD)(l)) >> 16) & 0xFFFF))

Returns the high word of the double word l. See also: MAKELONG Definition at line 458 of file common.h.

#define LOBYTE (  w   )     ((BYTE)(w))

Returns the low byte of the word w. See also: MAKEWORD Definition at line 430 of file common.h.

#define LOSWORD (  l   )     ((SWORD)(DWORD)(l))

Returns the low signed word of the double word l. See also: MAKELONG Definition at line 466 of file common.h.
