AffineTransform make an image move

[Mauricio Lopes]

I've been trying to make an image rotate in a panel. I did it. But also i want the image to make a translation.

Here is the code i tryed at paintComponent() :

//////////////////////////

Graphics2D g2 = (Graphics2D) g ;
AffineTransform at = new AffineTransform() ;

// at.rotate ( angle in radians ) ;
at.rotate( this.getAngulo(1, 1) ) ;

g2.drawImage(imgemFlecha, at, this);

/////////////////////////////


I cant change image x,y doing this drawImage(). I want to make that change.

Any suggestions ?
