der Beitrag von NamenLozer hat mich inspiriert,
Versuchs doch mal mit
SetCanvasZoomFactor(Printer.canvas,70);
Delphi-Quellcode:
procedure SetCanvasZoomFactor(Canvas: TCanvas; AZoomFactor: Integer);
var
i: Integer;
begin
if AZoomFactor = 100 then
SetMapMode(Canvas.Handle, MM_TEXT)
else
begin
SetMapMode(Canvas.Handle, MM_ISOTROPIC);
SetWindowExtEx(Canvas.Handle, 100,100, nil);
SetViewportExtEx(Canvas.Handle,AZoomFactor, AZoomFactor, nil);
end;
end;
