Can you copy the TLabel->Canvas into a bitmap

I have a need to be able to take the Caption of a TLabel (as it appears in
the label, not the text of it) and make it into a TBitmap.  I know you can
write a bitmap to a canvas but how would you take a canvas and make a
bitmap.

Or if it would be easier, how would you create a bitmap of font formatted
text?

Thanks in advance.

John

Hi John,

below the code which paints a text into a bitmap.

------------------------------------------------------------------------
    AnsiString Msg = "Quod erat demonstrandum";

    Graphics::TBitmap* B = new Graphics::TBitmap;

    TCanvas* C = B->Canvas;

    C->Font->Name = "Arial";
    C->Font->Size = 20;
    C->Font->Color = clYellow;

    C->Brush->Color = clBlack;

    B->Height = C->TextHeight( Msg );
    B->Width = C->TextWidth( Msg );

    C->TextRect( C->ClipRect, 0, 0, Msg );

    [ use B ]

    delete B;
------------------------------------------------------------------------

HTH

Regards

Giuliano

try something like this..
mybitmap->Canvas.CopyRect(Mylabel->ClientRect, Mylabel->Canvas,
Mylabel->ClientRect);
