怎样使用自己的位图填充form做背景:
unit Unit1;
interface
uses
SysUtils, WinTypes, WinProcs, Messages, Classes, Graphics, Controls,
Forms, Dialogs;
type
TForm1 = class(TForm)
procedure FormCreate(Sender: TObject);
procedure FormPaint(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
Bitmap: TBitmap;
implementation
{$R *.DFM}
procedure TForm1.FormCreate(Sender: TObject);
begin
Bitmap := TBitmap.Create;
Bitmap.LoadFromFile('C:/WINDOWS/cars.BMP');
end;
procedure TForm1.FormPaint(Sender: TObject);
var
X, Y, W, H: LongInt;
begin
with Bitmap do begin
W := Width;
H := Height;
end;
Y := 0;
while Y < Height do begin
X := 0;
while X < Width do begin
Canvas.Draw(X, Y, Bitmap);
Inc(X, W);
end;
Inc(Y, H);
end;
end;
end.
