Problem

cfish & fcfish crash

The error seems to happen during png output generation.

Wgraph:Demo importance

graph "Demo_importance" . {
  edge A B {}
  edge B C {}
  edge A C {}
  view cfish
}

pfish doesn´t want to show nodes

Is that a bug or a feature? Or must one set importance to some value?

The cfish/fcfish crash has been fixed, but the nodes are now missing in these examples, too. We're trying to figure that one out right now.

As a (funny but useless) side note, we found out that the crash only occurred on 32-bit machines, not on 64-bit ones.

Update: the nodes are no longer missing, a new version of aiSee will be made available shortly. However, there are still some node placement irregularities when exporting fish-eye views. I am not sure these can be completely ironed out in aiSee 2.x -- and in aiSee 3.x, fish-eye views have been dropped altogether. At the end of the day, I don't think that's a huge loss for Wgraph anyway -- while fish-eye views are a useful navigation technique in the context of a rich GUI, they are basically useless in the context of a static image.
