Like taurus said it's 1024 that is right.Originally posted by canadian_divx
does anyone know why windows labels them that way??? like why dont htey just make it like the manufacture?
interesting... i never noticed that 2^24 = 16.7m. are the extra 8 bits ignored, then? or what are they used for?Originally posted by Zedric
32 bit colour is also 16.7M colours btw, but that's because the extra 8 bits isn't for the colour.
In graphics, a portion of each pixel's data that is reserved for transparency information. 32-bit graphics systems contain four channels -- three 8-bit channels for red, green, and blue (RGB) and one 8-bit alpha channel. The alpha channel is really a mask -- it specifies how the pixel's colors should be merged with another pixel when the two are overlaid, one on top of the other.
Typically, you wouldn't define the alpha channel on a pixel-by-pixel basis, but rather per object. Different parts of the object would have different levels of transparency depending on how much you wanted the background to show through. This allows you to create rectangular objects that appear as if they are irregular in shape -- you define the rectangular edges as transparent so that the background shows through. This is especially important for animation, where the background changes from one frame to the next.

Yep, right on.Originally posted by taurus
so that's my explanation as to why smoke looks so much better in 32-bit than in 16-bit.
