If the PNG image defines the value of the Depth field using two numbers, such as 8/2-bit, GraphicsMagick (which is the backend library for prawn-gmagick) reads this as 2 instead of 8. Apply a patch to prawn-gmagick that detects this scenario and goes back to the image blog and reads the correct value.
