Resizing images

Postby Graham Mills » Mon Mar 16, 2015 8:05 am

Bit of a n00b question: the norm in SL, I believe, was to resize images/textures to powers of 2 from 128-1024 before import. Is it still good practice in OpenSim? If so, are there any good online tools that people use that don't require registration?

The powers of two is a requirement of the viewers, so it is the same everywhere.
And it comes from a fundamental computer graphics algorithm for scaling texture maps onto triangles.
It is probably burned into the hardware of the GPU.
So it is likely to stay with us for a long time.

I use GIMP (GNU Image Manipulation Program) for all my texture work. (It is better than PhotoShop after all!) So I use it to scale textures to powers of two.
