Flipping images

Is there any built-in way to flip the direction of an image post loading?

It appears that there is a command for rotation, but non for flipping vertically or horizontally?

Use negative scale, like this:

Graphics 800,600
Local MyImage:TImage=CreateImage(32,32)
DrawText "test",0,0
Flip
GrabImage(MyImage,0,0)
Cls
SetScale(-1,1.0)
DrawImage(myimage,100,100)
Flip
WaitKey
