Here Texture Loading by JXA !

[broumbroum]

Hi all ! Since some have asked for this, I'm just releasing a limited TEXTURE LOADING pack for the LWJGL.org forum here.
there are at most 3 java classes files.

Code:

Sf3Texture._loadTexture(BufferedImage, 0);

Loads a texture in a DataBuffer and

Code:

validatePixelBuffer();

converts the DataBuffer to any format you want : specify a GL Texture format as _ExtAbgr value and you're on (hopefully) !

Sf3Texture is HIGHLY INSPIRED BY DevIL TextureLoader class I've been found on the web last year. LoL

Hi !
updated the link with a new zip, because of the last crash with the webservers, it was broken.
 

EDIT : updated the BufferIO, for re-using of direct buffers (not a big deal =)

awesome, what image formats are supported?  what features are supported (scaling, cropping, etc.)?

[broumbroum]

That's supposed to be any by ImageIO.read(f) supported image formats...

Cool, I can make good use of that. My own texture loading routine is not as performant as it could be as I had problems with some PNGs. On my computer they would show up normal and on a friends computer they looked bluish. If I changed from RGB to BGR it looked ok for my friend but blueish on my machine ^ ^ Therefore I always copy the complete image into another temporary BufferedImage, which makes my texture loading about twice expensive as it should be  

How about including this officially into LWJGL? Maybe not into the core but as optional extension. I see two main reasons for that:
- If these would be official classes they would receive the same treatment as any other LWJGL class when making changes to LWJGL (otherwise a future LWJGL version could make the classes incompatible)
- Pretty much every game developer needs the ability to load textures. If you program it yourself you might not end up with a solution that is as performant as it could be (see my example above)

The recommended way is actually Slick-Util (can also load fonts and sounds/music):

http://slick.cokeandcode.com/downloads/util/
http://slick.cokeandcode.com/javadoc-util/

I completely agree that it would be nice to have LWJGL already include image/music loading.  It does have built-in wave loading.  However, I'd rather it not use ImageIO (which Slick-Util and most image libraries out there use)...

[broumbroum]

I've never been using slick, because I've got good performance with my code.
@jeditofu I also have coded a Sound loading class, which I could provide here. It relies on the same BufferIO class, and has some calls to the jlayer API when handling mp3's. I'll look for an upload soon.
@mstWeal thank you for your feedback, you're welcome ! You may want to post your comment on sf.net/projects/sf3jswing for rating .


EDIT : I'll post an [RFE] soon. cu
