Re: [pygame] Rotating Images on a specified axis.

[Farai Aschwanden <fash@xxxxxxxxxx>]

ANY image transform operation does distort a image in a bigger or  
minor way. You have 3 possibilities to solve this "problem":
1. Using a existing rotate function (best thing is to work always  
with the original for most less quality loss when rotating)
2. You paint the tank and the turret in every desired angle (be aware  
of rotate functions inside paint programs! ;) )
3. You use OpenGL and do it vector based

the easiest way is using the existing rotate function: easy to use  
and works fast.

Thats all I can say about it.
