|
|
; Single 32b pixel drawing macros
|
|
; Usage :
|
|
; DRAWMETHOD_XXXX_MACRO *pixelIN, *pixelOUT, COLOR, WR1, WR2, WR3, WR4
|
|
; Only the work registers (WR) can be touched by the macros
|
|
;
|
|
; Available methods :
|
|
; DRAWMETHOD_DFLT_MACRO : Default drawing method (Actually OVRW)
|
|
; DRAWMETHOD_PLUS_MACRO : RVB Saturated per channel addition (SLOWEST)
|
|
; DRAWMETHOD_HALF_MACRO : 50% Transparency color drawing
|
|
; DRAWMETHOD_OVRW_MACRO : Direct COLOR drawing (FASTEST)
|
|
; DRAWMETHOD_B_OR_MACRO : Bitwise OR
|
|
; DRAWMETHOD_BAND_MACRO : Bitwise AND
|
|
; DRAWMETHOD_BXOR_MACRO : Bitwise XOR
|
|
; DRAWMETHOD_BNOT_MACRO : Bitwise NOT
