VAR
newbmp:TBitmap
i,bmpheight,bmpwidth:integer //推拉
begin
newbmp:=TBitmap.Create
newbmp.Width:=image1.Width
newbmp.Height:=image1.Height
bmpheight:=image1.Height
bmpwidth:=image1.Width
for i:=0 to bmpheight do
begin
newbmp.Canvas.CopyRect(Rect(0,bmpheight-i,bmpwidth,bmpheight),image1.Canvas,Rect(0,0,bmpwidth,i))
