Can anyone explain how the Fmod option is implemented?

From the docs: inside=fmod colors inside pixels according to the magnitude of the last orbit point which is within a set distance from the origin. Then: color = magnitude * colors / closeprox

The magnitude is checked against closeprox at every iteration, if magnitude is less than closeprox, it is saved. This happens until the iteration bails out or the max iteration count is reached. Then the pixel is colored using the last saved magnitude, as described above. Jonathan
