It depends how you want the user interface to look like.
Using a macro, you could call the waitForUser(string) function to wait
until a selection has been made (line selection for length measurements,
free hand ROI for the wing areas). You could even use the setTool(tool)
function to switch automatically to the tool appropriate for the next
task.
To measure the area, you can use the getStatistics() function, and for the
length of the line selection, I'd recommend to use the
getSelectionCoordinates() function.
The results, you could put into the results table, as illustrated in this
example:
http://rsb.info.nih.gov/ij/macros/SineCosineTable.txtIf you want to do something more specialized (such as intercepting when
the user has selected something, and not requiring a click on the
wait-for-user dialog's OK button), you'll have to use Java. Just make up
your mind what you want, and describe it in a bit more detail.
