I'm not sure if I understand what you mean. I understood that in 32 bpp a tile was 256x127 px. So if you've got an image of 64px wide, isn't it supposed to be the quarter of a tile?
I took a quick look in the code, and think it would be possible by a little code patch, and abusing the compression flags in the info file, but the result would not look good: every pixel of the original image would take 4 pixels on the screen, ie very blocky. So why would you want to do that? When the 32 bpp project is finished, all graphs would have to be 256 px to look good. And if you want to use existing 64 px images until that moment, you could use a program like IrfanView to convert them in batch mode.
Don't say this unless you want DaleStan
to open his mouth again...
You can see that the problem-bug is with menus, where buttons should remain same size regardless of zoom, but currently they don't. Just use the new toolbar to understand me.
Using an extention _z0, _z1, _z2 ... the png replaces the original sprite in the specific zoom only (256, 128, 64...). The problem is that if you use a 64px png-sprite with extension _z2 (zoom level = normal 64px) only, the code cannot accept it as it protests that it is missing sprites for z0. IT is very stupid. If you can fix it you are top coder,
, and we will appreciate you!
