DstX, DstY	Integer	Destination offset coordinates.
DstClip	TRect	Destination clip rectangle.
SrcF	TCustomBitmap32	Foreground source bitmap.
SrcRectF	TRect	Foreground source rectangle.
SrcB	TCustomBitmap32	Background source bitmap.
SrcRectB	TRect	Background source rectangle.
BlendCallback	TBlendReg	Low-level register blend procedure.

Overload 2

procedure BlendTransfer(Dst: TCustomBitmap32; DstX, DstY: Integer; DstClip: TRect; SrcF: TCustomBitmap32; SrcRectF: TRect; SrcB: TCustomBitmap32; SrcRectB: TRect; BlendCallback: TBlendRegEx; MasterAlpha: Integer); overload;

Blends foreground and background bitmaps into Dst with a master alpha level.

Parameter	Type	Description
Dst	TCustomBitmap32	Destination bitmap.
DstX, DstY	Integer	Destination position.
DstClip	TRect	Clip rectangle.
SrcF	TCustomBitmap32	Foreground source bitmap.
SrcRectF	TRect	Foreground rect.
SrcB	TCustomBitmap32	Background source bitmap.
SrcRectB	TRect	Background rect.
BlendCallback	TBlendRegEx	Extended blend function.
MasterAlpha	Integer	Master alpha weight [0..255].

Description

BlendTransfer combines corresponding pixels from two source bitmaps (SrcF and SrcB) into Dst using high-performance register blend routines.
