Hi, I really need to know the size of the texture loaded into the

jit.gl.texture object, but no matter what file I load, I always get dim 255

What do you see that's wrong here? Everything looks good to me. I

would expect to get 256 256 0 which is what I get with jitter 1.5.2 on

Ah sorry I meant to write 256 256 0 instead of 255 255 0 :-

What I hoped to see was the dimensions of the file that is loaded. Otherwise

how can you know how big your texture is? And what does 256 256 0 stand for

Fair enough. It actually does work....just not right away. The

texture has to be bound before its adapt attribute will kick in a

resize the texture and change the dim attribute. This is because

Jitter is a very harsh environment for opengl and textures are

sensitive creatures that need a proper home in a living opengl

context. So, jit.gl.texture exhibits some delayed behavior that only

kciks in when you actually use the thing. This patch shows that it

Can I post that to cuteoverload.com? That made my heart warm and

aha! thanks a lot wes. I was getting really nervous about my deadline in 2

In case anyone cares, I use this to do relative blurring of the texture. If

you project a large texture onto an object, and then scale it down, the

texture looks really ugly because the downsampling doesn't do interpolation.

Joshua suggested to use a blurring shader. This looks really nice, but you

have to set the width attribute of the shader relative to downsampling

factor. To calculate the downsampling factor I needed the texture dimensions

I guess it's going to work now. Thanks again.

jit.gl.texture @dim broken?
