Complex

This image has the same inteface as Image2D but with a cubic complex domain.

Also, we can iterate on :

• 0 face pixels (little squares)
• 1 face pixels (medium rectangle)
• 2 face pixel (big squares)

Neighborhood is implemented so that :

• from a 0 face pixel we can get the 1 face pixels and/or 2 face pixels
• from a 1 face pixel we can get the 0 face pixels and/or 2 face pixels
• from a 2 face pixel we can get the 0 face pixels and/or 1 face pixels
