Rotating Images in Java

Magown3 · 13-04-2006 09:01PM #1

I'm trying to trying to rotate an Image in java without any luck.

It's for a J2ME game and I've looked at the Image Api and cannot find any Image.rotate() methods!!

Anyone out there know how to rotate images. Also, seeing as they will appear on a Canvas, ImageIcons won't work... (I think)

Is the image a sprite or have you added it to a layer ? or something different ?
I will have a look and try with the scenario you have.

Don't know if this is any use to you:

Hope that is something along the lines of what you were looking for, or at least helps in some way.

bishopLEN,

Yes they are Sprites. I've also written my own Sprite Class. Here's some of my code:

private Image blueAtom, redAtom;
...
blueAtom	 = Image.createImage ("/res/cars/subaruImpreza.png");
...
//public Sprite (Image img, int xPos, int yPos, int xVel, int yVel, int z, int wBnds, int hBnds, int ba)
localSprite  = new Sprite (blueAtom, localX,  localY,  0, 0, 0, getWidth (), getHeight (), Sprite.BA_BOUNCE);

I've had a look at this but it's quite jumpy and unrealistic. Any way to improve this?

sound_wave,
I actually had a look at that page just before I posted here but I think that it's rotating the entire JPanel. But I like the way it's so smooth... it looks good

I presume you tried the sprite setTranform() method...

Also are you using MIDP1.1 or 2.0 ?
