Hi I'm new here and I've got a very quick question.
Is there any way of rotating an image in java? For example, I have a picture of a car and I want to prompt the user to enter a number between 1 and 359. The program then rotates the image by that many degrees. I just want to know because it will take way too long for me to add the rotated images one by one.
Thanks in advance. |

hello, and welcome to compsci!
after looking thru the api things that might be able to help you out,
Graphics2D -> drawRenderableImage() and rotate() |

HeavenAgain might be right, but when I've done it I've used AffineTransform. AffineTransform basically rotates the whole drawing context which is why I save the current settings first then reset them after.
code: | public void draw (Graphics g)
{
Graphics2D g2D = (Graphics2D)g;
AffineTransform saveXform = g2D.getTransform();
AffineTransform at = new AffineTransform();
at.rotate(direction,posX+25,posY+25);
g2D.transform(at);
g2D.drawImage(shipPic,(int)posX,(int)posY,panel);
g2D.setTransform(saveXform);
} // end of draw()
