Hi, I'm using a matrix to hold images drawn by jit.gl.mesh before

saving them as an image file. I was trying to make hi resolution images (for printing) but can't seem to be able to save images above 2000x2000 pixels. Is there a reason for this limit - either in jit.matrix or in the exportimage routine? It doesn't seem to matter which file format I choose.

I think there is some kind of a limit on the context&texture sizes if 

using hardware accelerated opengl, so I've just tried to render to the 

9000x9000 matrix and then export - and it seems to be 

fine(9000x9000png). Didn't try with FSAA on though...

I've also tried with the 16000x16000 matrix, but max couldn't allocate 

it in on my 2GB system(is it a ~1GB matrix?).

Here is the test patch I used:

I tried your patch and what I get is that [jit.gl.mesh] only draws into a small portion of the 9000 x 9000 matrix starting at the bottom left corner. Actually that's what I'd seen with my patch too, but forgot to say that!

i assume your patch draws over the whole matrix on your machine?

mine is a g4 powerbook with 1.25 gig ram. maybe that's it - that I need more RAM? strange.

I've just tried it again, with simple test pattern and i see the whole

so... who knows. I'm using fresh mbp with 2gb ram.

But you're welcome to come over to den haag today, and we can try to 

ps. I missed my flight at friday. and today. I'll try tommorow.

oops, it seems that I've mistaken you for another Justin, but you're

I live in Den Haag too! (but temporarily in amsterdam)

will try puzzling. I just don't have enough memory i think

maybe you didn't mistake me?

will try puzzling. I just don't have enough memory i think
so I'll have to try tricking it somehow.

exportimage size limit?
