It turns out that my problem was mostly self-inflicted. Since Albert Cardona has been kind
enough to point me in the right direction, I would like to post the solution in case somebody else
has the same problem:
- First, on a more powerful computer (20" iMac, 2 GHz Core Duo, 2 GB RAM, OS 10.5.6 vs. 12"
PowerBook, 867 MHz G4, 640 MB RAM, OS 10.4.11), TrakEM2 under Fiji is much more responsive
and the visual feedback is much better.
- Second, my understanding of how the Bezier handles work was not quite right. I was trying to
move them independently to create a corner. However, the right way to do that is to move them
both as close as possible to their anchor point and then adjust the anchor point and its neighbors.
- Finally, at high-enough zoom levels for the handles and the anchor point to be clearly
distinguishable, I have to click somewhere besides the handles instead of directly on them, as if
the mapping of the cursor position is systematically off. Same thing under Linux, so it could be a
Java graphics issue.
Cheers,
Richard
