Draw an imaginary straight line through the center of the head tube that extends all the way to the ground. If the axle falls on that line, regardless of the shape/curve of the fork, rake exists.
If the forks are straight, and there is no change in angle between steering tube and fork, there will be zero rake.
In the case of the new Fujis pictured, there is a slight bend between steering tube and forks, so the axle ends up ahead of the imaginary line.
Straight (or curved) forks can have rake (or not) depending on how things are configured.
