[RESOLVED] Non power of 2 textures.
Is there a way to use non-power of 2 textures in grrlib? If not, then is there a way to detect if a texture was loaded correctly?

Re: [RESOLVED] Non power of 2 textures.
Texture needs to be a multiply of 4, not just power of 2. It is not GRRLIB fault if this limit exist, it's Wii related.
So if you need to check if it's going to work or not just a % 4 on the width and height. If the result is not equal to 0 for both of them, than it will fail.
Code:
if((Pic->h % 4) || (Pic->w % 4))
{
// failed

Couldn't grrlib resize the texture until it's a multiple of 4? Just adding blank spots on the bottom and right, while keeping the img width and height values of the original?

Re: [RESOLVED] Non power of 2 textures.
Sure we could code this, but GRRLIB is already "LAZY CODER" Friendly 
and adding "transparent col/row" will introduce possible eroneous positioning (ie centering...)
in one word !! make your pic as you want, add transparency row/col with gimp if you want
or even better since GRRLIB is an open source project, just code what you need
