Using Eigen Array-of-Arrays for RGB images

Question

I\'m trying to use the Eigen library for some simple image processing. I\'d use Array3f for an RGB triple and an Array to hold an RGB image. This seems to work partially, an

Answer 1

I think Eigen was not meant to be used in this way (with vectors as "scalar" types). I don't know what causes some of the expressions to compile, but for the ones that don't, it's because Eigen sees a + operation on two Arrays, with the left Array's scalar = Array3f, right Array's scalar = float and flags it incompatible.
