[sdljava-users] Image Rotation

[<lem...@nw...>]

Hello,

I've started to port my C/SDL game (CarWars / http://www.nwolf.org/carwar=
s)=20
into JAVA with JAVA SDL binding.
I'm looking for a method to rotate and resize an image... (Before, I was =
using=20
a C library that was working pretty good ;))
Any idea ?=20
I've read that it's possible to use java.awt.Image or 2DGraphics with JAV=
A=20
SDL, is that true ? Any example ?

Thanks ;)

Greetings,

There are a few options.  One is to use the SDL_Gfx library.  Look in 
SDL_rotozoom.h.  Another is to try using something like java.awt.Image 
or 2DGraphics.  I havn't tried this myself.  However if you get the 
pixels in the correct format it should probably work.  You can access 
the bytes of the SDLSurface very quickly with the 
SDLSurface.getPixelData() method.  Finally you could just use OpenGL.  
Draw your sprites as Quads and then rotoation is no problem.  If you 
look at org.gljava.opengl.Sprite class this already takes care of doing 
that.  If you browse in there you should be able to see how to load an 
image, turn it into a sprite, and get it displayed.  OpenGL is probably 
the best way as you will get all the awsome features of OpenGL for free.

Cheers,
