image rotation

[Andres Q]

Hi,

In a game I'm working on I have an image of an arrow which I rotate accordignly.

In the screenshot below the arrows on the left (which are pointing to the right) aren't rotated and look fine, however the arrows on the right (the ones pointing to the left) are rotated PI degrees (float value 3.1415927) but as you can see they don't look truly pointing left, it seems that the arrow is pointing 1 pixel upwards and not entirely left.

This is on Java backend, I'm not sure if this is a bug somewhere on my code and/or if there's anything I can do about this? Ideas? Thanks
