Since LWJGL is becoming very stable, what do you think of making a binding of DevIL (also know as OpenIL) ? It could be in a separated package, but I think it can be pretty interesting because it works evry well, support a large amount of image format and its usage is very similar to OpenGL, so it can be integrated with OpenGL without the need of AWT or SWING…
It’s just an idea…

I have actually been thinking about this for quite some time too - alas I am busy enough with lwjgl/fmod. If someone wants to commit to it, we can include it in lwjgl and host it in the CVS too. Unless ofcourse said project doesn’t want to be under the lwjgl “umbrella”.
But yes - DevIL is a perfect match for lwjgl!
That would be so incretibly cool. I’ld do it myself if I could 
There definantly is a want for such a thing.
Ooooh! Me like!!! Could do with removing support for most of those wacky formats though and just leaving the important ones.

Just curious…
What is the point? The JDK comes with loaders for JPG and PNG, and as I recall, Cas used a custom format for Alien Flux anyway.
When you are ready to deploy the game the end result only has to load the image format that you have settled on. It might make more sense to just have a conversion tool that gets images into a custom format. Keep the size of the downloads small.
[quote]Currently, DevIL can load .bmp, .cut, .dds, .doom, .gif, .ico, .jpg, .lbm, .mdl, .mng, .pal, .pbm, .pcd, .pcx, .pgm, .pic, .png, .ppm, .psd, .psp, .raw, .sgi, .tga and .tif files.
Formats supported for saving include .bmp, .dds, .h, .jpg, .pal, .pbm, .pcx, .pgm,.png, .ppm, .raw, .sgi, .tga and .tif.

That’s way too much.
load: dds, gif, jpg, png, tga
write: tga
That would be enough imo. Well, gif could be thrown out as well… it rarely smaller than 8bit pngs.
It’s jpeg loading from bytestreams that interests me the most. I currently have a dependency in Super Elvis on AWT as a result of jpeg loading.
Cas
ive noticed it takes 1500~ millis for a png to a jpg to load via Java’s own loaders into OpenGL using LWJGL. However, with a customisable TGA Loader, it takes around 70 millis. So loading via Java’s own loaders are a bit too slow.
So all in all, i think this would be a great addition to lwjgl.

TGA vs PNG loading? Isn’t that a little unfair

If we had a fast/non-awt way of reading images, most custom formats/loaders would be unnecessary.
+1 from me.
[quote]TGA vs PNG loading? Isn’t that a little unfair
[/quote]
Hm… well extremely zipped TGAs are just about 10% bigger than PNGs. If it still loads much faster and your download gets only 100-200kb bigger it might be a good option.
FYI kzip performed a bit better (~1%) than 7zip. Eventually you can get rid of some more bytes by testing several command line switches (both programms).
Well, the images I used for testing are much smaller (only 1/6) as jpg (without any visible loss). So it’s always a good idea to check which format suits best.
Sorry, I’d made the assumption that the TGA loader in question was home brew loosely based on the shabby version contained in nearly every texture loading OpenGL example for C++ in existence.
It makes it look really good but of course only loads a particular format of TGA, i.e. raw and uncompressed. It was at the point be very unstandable why PNG would take considerably longer than TGA.
Kev
raw and uncompressed
Yea yea… raw and uncompressed… it’s already compressed, because it’s jared (wereas all other formats get compressed twice without any noticeable gain from the second [jar] stage).
edit:
On a second thought. Benchmarking should also take “stored” compressed formats into account (so no additional compression for png). That should be a bit faster then.
So, what do you think, should we make the OpenIL a native binding or should we make it in pure java ?
Personnally I vote for the pure java version…
Chman
definately a binding. Doing it injava would be a waste of time - people could just as well use ImageIO then.

I’ll give it a shot. Give me a few of days to get a bare bones implementation going. It doesn’t look hard to do it in JNI. Once I get something in there, you can decide if you want all portable features or just a subset.
[quote]definately a binding. Doing it injava would be a waste of time - people could just as well use ImageIO then.
[/quote]
So what’s the point at all then? If AWT dependance is the only problem, I’d suggest just a couple of most used file loaders (I’d guess only .png and .jpg should do) made in pure java instead of bringing in another .dll, .so etc. plus all required additional maintenance and deployment hassles.
Just my 2cts.
Porting the JPEG decoder ain’t gonna be fun
