"Most of these formats output 24 bits per pixel with 8 bits for each of red,
green and blue data. PNG and PPM allow you to optionally specify the output bit
depth from 5 to 16 bits for each of the red, green, and blue colors, giving from
15 to 48 bits of color information per pixel. The default output depth for all
formats is 8 bits/color (16 million possible colors), but this may be changed
for PNG and PPM format files by setting Bits_Per_Color=n or by specifying +FNn
or +FPn, where n is the desired bit depth."
