Overload Details

Overload 1

procedure DrawTo(Dst: TCustomBitmap32); overload;

Draws this entire bitmap onto destination bitmap at (0, 0).

Parameter	Type	Description
Dst	TCustomBitmap32	Destination bitmap.

Overload 2

procedure DrawTo(Dst: TCustomBitmap32; DstX, DstY: Integer); overload;

Draws this entire bitmap onto destination bitmap at (DstX, DstY).

Parameter	Type	Description
Dst	TCustomBitmap32	Destination bitmap.
DstX, DstY	Integer	Destination coordinates.

Overload 3

procedure DrawTo(hDst: HDC; DstX: Integer = 0; DstY: Integer = 0); overload;

Renders this bitmap onto a target GDI device context (HDC) at top-left position (DstX, DstY).

Parameter	Type	Description
hDst	HDC	Target GDI device context handle.
DstX, DstY	Integer	Top-left destination coordinates.

Overload 4

procedure DrawTo(hDst: HDC; const DstRect, SrcRect: TRect); overload;

Stretches a sub-rectangle of this bitmap onto a target GDI device context (HDC) rectangle.

Parameter	Type	Description
hDst	HDC	Target GDI device context handle.
DstRect	TRect	Target destination rectangle on HDC.
SrcRect	TRect	Source sub-rectangle on this bitmap.

Description

DrawTo renders this bitmap surface directly onto another bitmap or an external OS GDI device context (hDst).

Example

// Paint bitmap onto Form's Canvas handle in OnPaint event
Bitmap.DrawTo(Form.Canvas.Handle, 0, 0);
